Unable to write tmc spi 'stepper_z' register GLOBALSCALER

New Hybrid Core v4 build, has never worked (brand new). Assembled machine, wired it, using custom DIN mount electronics enclosure.
Using Octopus EZ Max with EZ5160Pro drivers, but can repro it using an entirely independent Ocropus Pro 1.1 using TMC5610T Pro v1.0 drivers. EBB42 board. RatOS can see the Octopus and the EZ42b, can flash them both no problem. Any time I enter any gcode commands i.e. initial BEACON_INITIAL_CALIBRATION, or STEPPER_BUZZ STEPPER=stepper_x (using any stepper letter) I get this: Klipper reports: SHUTDOWN Unable to write tmc spi 'stepper_z' register GLOBALSCALER Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown I've reproduced this problem using a 100% independent Octopus 1.1 Pro board I had (new but untested). I've swapped to a replacement EBB42 board, same issue. I swapped the drivers themselves from x and other ports, same thing (on both cards). Also swapped the ports the motors are plugged into. Same thing. I've swapped the Pi (same SD card though), same issue. I've swapped in a new Beacon, same issue. I'm running out of ideas. I 100% acknowledge this is probably something dumb I'm missing - a jumper, configuration, something. Maybe an endstop related issue? Crimps/wiring? Any suggestions? Attached are printer.config, klipper log, picture of the Octopus EZ Max board. Happy to share anything else as needed. (NOTE: Probably alot of permutations in the klipper log with various things I've changed; sorry). Would greatly welcome any ideas to troubleshoot this.
Solution:
Thank you! Confirmed I fixed this - had a mismatch of driver slot install and motor cable port. SMH, this has been killing me....

That means klipper can't communicate with your z driver If you haven't selected 5160 drivers, not configured your driver jumpers correctly (in case of the octopus pro) or haven't selected the correct slot (you've moved your drivers around), you'll get an error like this. If you can't figure it out based on that information alone, please post a debug zip, so i can see how you've configured your motor slots.

What if you only have Diag Pins and not any other jumpers able to be set. I get that error and its on Kraken 1.0. If so is it software related error vs a hardware jumper. I dont have the option in the RatOS setup wizard to change drivers it only allows TMC2160. In the printer.cfg it has no reference, but, the RatOS.cfg is says they are "tmc5160 stepper_x". I am new to all of this But, I am not sure what is going on with two conflicting drivers being listed in different places.

What?
I dont have the option in the RatOS setup wizard to change drivers it only allows TMC2160
It should say "Kraken 2160 Plus" on the first 4 slots, and "Kraken 2160", you can't change them since they're solderen onto the board.
"tmc5160 stepper_x"
This is correct, the first 4 slots should have 0.022 ohm sense_resistor and the last 4 should have 0.075. (in RatOS.cfg)
I am not sure what is going on with two conflicting drivers being listed in different places
You need to select the motor slot where you have connected the stepper. Make sure everything is updated before you select a printer and go through the configuration steps. If you still have problems, please start your own thread.

@miklschmidt Sorry. "What if you only have Diag Pins" was in response to a past post on this same issue. I am new to posting in discord.
miklschmidt
miklschmidtβ€’2mo ago
Like i said, you can't choose drivers on a board that has the soldered on there (that's why the "integrated" tag is there). They're correct in the screenshot - because RatOS already knows those are soldered to the board. Slot allocations look correct too. I'm guessing you just forgot to connect the motor power?
WOPR73
WOPR73β€’2mo ago
@miklschmidt I have 2 new 24v Meanwell. 1 for the Board and 1 for the motors. I tested both power in connections at the board both getting 24.31v. the always on fan pins all getting 24v as well. @miklschmidt I am at a loss to what to do next. I am at a clean install with all of the updates using update manager. except the Beacon. ( which would install a lessor version if I did)

Wait what's going on with the PSU's here, that's not a great idea You have motor + connected to one and gnd to the other. Ah i'm blind never mind Followed the wrong cable πŸ˜‚ This is fine. Post a debug zip (download from the sidebar in the configurator)
WOPR73
WOPR73β€’2mo ago
there is a connection in the bottom right where the power comes in lol ok it will have a bus bar and such later on.
miklschmidt
miklschmidtβ€’2mo ago
You need to connect the - of PSU 1 and PSU 2 if you haven't It should be done internally on the board, but it might not be
WOPR73
WOPR73β€’2mo ago
if i understand you correctly that connect is made on the psu1 on the fastend to the board for now. it will be changed. lol
miklschmidt
miklschmidtβ€’2mo ago
I looked but couldn't find that connection. I'm talking about the 24V side Also why are you using 2 PSU's? A single 350W is more than enough
WOPR73
WOPR73β€’2mo ago
both power supplys are supplying power to the board. psu1 is supplying 24v to the drivers/motors. psu2 that is sitting on the right side heat bed is supplying 24v to the board
miklschmidt
miklschmidtβ€’2mo ago
In fact it runs on 200W.
WOPR73
WOPR73β€’2mo ago
well that cause BTT said that might be the issue.
miklschmidt
miklschmidtβ€’2mo ago
Who from BTT said you should use 2 PSU's? ... Did they ask you what steppers you were using? This board makes no sense for the V-Core 3 in the first place, those first 4 drivers have no place in a 3d printer. 0.022 ohm requires at least 6A RMS motors if you don't want horrible microstepping performance.
WOPR73
WOPR73β€’2mo ago
they know what the board is... it came from sorry [email protected] where I bought it from.
miklschmidt
miklschmidtβ€’2mo ago
The board is just one part of the equation. All that matters for power usage is what amperage you're running your steppers at (because the bed is AC, and that leaves a ~50W average heater)
WOPR73
WOPR73β€’2mo ago
and service 005@biqu3d
miklschmidt
miklschmidtβ€’2mo ago
2 350W PSU's for 6 1.6A steppers and a heater is completely insane Regardless. Those drivers should not be failing to initialize
WOPR73
WOPR73β€’2mo ago
@miklschmidt I planned on doing that
No description
miklschmidt
miklschmidtβ€’2mo ago
Yeah but use the bed output, instead of the heater. Generally stick to the RatOS wiring diagram (which omits the AC connection, you can use the voron one for that part)

@miklschmidt thats from wiring 4.0.

WOPR73
WOPR73β€’2mo ago
@miklschmidt which they did state is was only the general idea. not to follow it to the letter.
miklschmidt
miklschmidtβ€’2mo ago
Reason for using the bed output over the heater port:
miklschmidt
miklschmidtβ€’2mo ago
Well that, and RatOS expects you to use the bed output πŸ™‚
WOPR73
WOPR73β€’2mo ago
I would rather us the bed output.
miklschmidt
miklschmidtβ€’2mo ago
Anyway.. I don't know why your drivers are failing to initialize. Try a full power cycle of the board, they may have gone into a wonky state. Followed by FIRMWARE_RESTART. I used a kraken recently without any issues. you can try unplugging the motor cables as well and see if that changes anything Now i gotta go, it's 5AM πŸ™‚

Thank you for the layouts. I have saved them for later ref. there is just to many sites saying that the SPI and some Max3xxx chip dont work together causing that error. then the not enough power to the motors. the screen shares the same spi or something... its just endless directions to go to keep testing things that "may be" the issue. oh and the misconfigured software settings. this is the place the Biqu3d sent me for a possiable fix. https://www.klipper3d.org/TMC_Drivers.html?h=uart#i-keep-getting-unable-to-read-tmc-uart-stepper_x-register-ifcnt-errors well. I will see if I can get them to exchange this board for another. maybe that will be the fix I am looking for. Thanks for you help
miklschmidt
miklschmidtβ€’2mo ago
That's plausible, sure, but RatOS doesn't use the Max31685 chip and it's a different error. It's an SPI communication error in that case.
then the not enough power to the motors
Not the case here
oh and the misconfigured software settings.
Also not the case here, unless you modified stuff? yeah that's the very basics, we already checked that The drivers are not responding I haven't seen if you've done something to your config though, you could still send me the debug zip and i can take a look.
Post a debug zip (download from the sidebar in the configurator)

@miklschmidt this is a newer install. I havent tried much other than to home an axis. But, anything to do with motors gives and error.
miklschmidt
miklschmidtβ€’2mo ago
Configuration is correct. Any issues is either electrical or actually dead drivers on the board.
WOPR73
WOPR73β€’2mo ago
@miklschmidt I never had magic blue smoke or anything seems as of there is something broke. everything has been smooth up until having to home any axis. I just figured that I was missing something really basic that I wasnt doing or clicking on.

Wait, did you not update package through the update manager?

yeah, so far I have not hear back from them on the return
miklschmidt
miklschmidtβ€’2mo ago
And you tried disconnecting all the stepper cables on the board right? It's not unlikely that the chips won't boot if you're shorting something by accident
WOPR73
WOPR73β€’2mo ago
yep I get the error even if I disconnect everything except for the thermistors. software must check this to make sure that they dont thermo runaway. had that issue on my MK3s I do have a hotend fan on all the time... except on reboot.
miklschmidt
miklschmidtβ€’2mo ago
it does yes. Sounds dead to me unfortunately just the drivers though.. which is weird
WOPR73
WOPR73β€’2mo ago
I just placed another order, but this time on Amazon. I figured that BTT will not do a return.
miklschmidt
miklschmidtβ€’2mo ago
You didn't get another Kraken right? I'd really advise you to get the Octopus Pro H723 instead It's a much better board And for 24V all you need is 2209's which are dirt cheap The Kraken won't run your extruder with any sort of accuracy whatsoever
WOPR73
WOPR73β€’2mo ago
isnt the Kraken a H723 as well?
miklschmidt
miklschmidtβ€’2mo ago
the first 4 slots won't run any 3d printer stepper with any sort of accuracy either. yes but the sense resistors on the first 4 drivers are completely overspecced, they suck for anything less than 6A per motor. The latter 4 wants at least 2A. I don't know who at BTT thought it was a good idea
WOPR73
WOPR73β€’2mo ago
yeah, I thought that a bit much. I see they launched a new Kraken motor as well.
miklschmidt
miklschmidtβ€’2mo ago
No that's some dude, has nothing to do with BTT. It's a 3A motor, so still won't work properly on the first 4 slots.
WOPR73
WOPR73β€’2mo ago
should I use 2209's on the extruder as well?
miklschmidt
miklschmidtβ€’2mo ago
yes It runs 0.707A. there's no point in going 2160 or 5160 for that (same driver except 5160 has a built in motion planner that we can't use). the 2160/5160 are only really useful for high voltage. But you need to order a version of the 2160/5160 that can actually do that.
WOPR73
WOPR73β€’2mo ago
ok, stopped the order and return when it comes.
miklschmidt
miklschmidtβ€’2mo ago
If you can get the TMC2240's those are better than the 2209's
WOPR73
WOPR73β€’2mo ago
ok, octopus Pro v1.1 with TMC2240s ok, done. with 2 extra 2240s just incase. Never had a board without the driver being built in. First printer other than Prusa. ok, thank you for the help. I am going to download the pdf on that board and read up. @miklschmidt ooh does this need a plugin wifi too? @miklschmidt ESP wifi module? I hope not Prusa had one on this mk4 when shipped and it was worse than dialup... yes, I used the BBS long long time ago.

@miklschmidt Ok, thank you. I will make sure to try that out. The one issue with 3.1 version that I have is the belt is angled just a bit looking at it from the front. Much better than the 4.0 tool head I tried. that was made for a different gantry all together.
miklschmidt
miklschmidtβ€’2mo ago
The one issue with 3.1 version that I have is the belt is angled just a bit looking at it from the front
This should not be the case at all. That would be an assembly issue or part incompatibility. 4.0 toolhead is not compatible with 3.1 (that's why it's 4.0 and not 3.2)
WOPR73
WOPR73β€’2mo ago
@miklschmidt yeah, I ran into that before i looked at the rest of the 4.0 changes. I just really like the 4.0 v-core 1.0 toohead combo. "I didnt think" that it would be an issue. tisk' tisk' tisk' that will teach me. lol I will make sure to reprint the "PP000346-rr_toolhead_vc3_front_V01_20240531.slt" and not any other. @miklschmidt and those belt tensioners... yummy! I hope that they work well for others then I will have to get me a little v-core 4.0 300. @miklschmidt Where is the display config located. I dont see anything in printer.cfg or RatOS.cfg. I know it running on the PI. shouldnt there be some kind of ref. to it somewhere?
miklschmidt
miklschmidtβ€’2mo ago
What exactly do you mean by display config? Do you mean OS level configuration of the screen at a device level, or do you mean KlipperScreen configuration, which is an application running on the pi that shows a UI on the screen, not the actual screen?
WOPR73
WOPR73β€’2mo ago
@miklschmidt I was reading over something last night that was talking about the printer config and was showing the pin ref to where it was to be connected on the board. Given Raspi is doing the leg work, I was wondering if there was some bit of config in RatOS.cfg or one of the files that is links too. @miklschmidt either way. no worries. Biqu is giving me the run around on the return. "Have you tried changing other drivers and configuring the driver files? Please provide a screenshot of your order and order number, and record a video of the error during use, and submit your configuration file so that we can help you feedback to the company."
miklschmidt
miklschmidtβ€’2mo ago
What kind of screen are you talking about here? Like an old-school OLED with an encoder wheel?
Have you tried changing other drivers and configuring the driver files?
:facepalm: ... they're soldered to the god damn board BIQU. You can tell them the config is correct and verified on several other krakens - you're using RatOS. Just provide them the klippy.log (download it right after reproducing the error) it has all that info in one file, including the configuration. Well it doesn't have the order and ordernumber obviously.. I suggest you go to BTT's discord instead. That sounds like some first level ali express rep.

@miklschmidt I should get a skip option here. no toolboard

Anyway, you can fix it by reselecting the printer in the Printer Selection step (just click the navigation to the right) Yes but you managed to create a broken config, maybe you selected a different printer and when reselecting the v-core 3 you chose "merge" instead of "start fresh" ?

miklschmidtβ€’2mo ago
Yes i can see this in your previous screenshot. Select a different printer, click "start fresh", then click the 500 v-core 3 and select "start fresh" again. That will solve the error. My guess is you merged a default printer config from a printer that by default comes with a toolboard into the v-core 3 defaults - which does not have a toolboard, and thus broke the config because a toolboard connected part fan isn't valid on a printer that doesn't have a toolboard selected. If in doubt, reselect printer and click "start fresh".

@miklschmidt I did have the heater pad installed directly into the bed connection on the main board. @miklschmidt Was hoping that I wouldn't have to use direct mains power to power the bed. But, I am getting timeout errors. 24.31v on all 3 power in, and 24.31 on power out on the bed.
miklschmidt
miklschmidtβ€’2mo ago
That doesn't work. The bed connector on the board should be connected to the DC side of the SSR. It's a 220V AC bed. It'll do nothing at 24V πŸ˜„

American? Well 120V then.. Explains the timeouts as that would overload your PSU at 24V i can't math, that makes it a 12 ohm bed, which works out to 2A at 24V. regardless, you'll get heater errors without connecting it properly

So let’s say you already own a Kraken, and were considering using it, would using running the steppers at 24v help this problem any more? I’m not an expert on stepper drivers and how they function.
miklschmidt
miklschmidtβ€’2mo ago
No, there's nothing you can do unfortunately. Even if you watercooled the steppers and overcurrented them, you wouldn't be able to reach anywhere close to the current required for the currentscaler to not drop under 16 with those ultra low sense resistors. it's just a huge designflaw.

@miklschmidt so for the 2504 or 2804 what drivers do you recommend? I can do 48v or 24v. Any place you can recommend to do some reading on this topic?
miklschmidt
miklschmidtβ€’2mo ago
First of all, forget the 2804, they make no sense on a machine like this, they don't have enough torque for you to get any benefit from the 1.5x torque drop off point. 2209 are fine on 24V. 2240 are marginally better (but best of all they have an integrated vsense circuit so they don't need the same kind of manual tuning regardless of current). For 48V get the 5160 (and make sure they can handle 48V), i don't think there are 2160 high voltage step sticks out there yet. Make absolute sure the 5160 drivers you pick are using the standard 0.075ohm sense resistor.
Any place you can recommend to do some reading on this topic?
TMC Datasheets It depends on what you already know. The TMC datasheets won't make much sense to you if you don't know how chopper drivers work or if you have no experience with basic electronic circuitry / signal processing. It's really hard making recommendations without knowing a persons level of understanding The best way to learn, is to learn how to acquire new knowledge and how to identify what pieces you're missing to understand the topic you're reading about. I'm not entirely there myself yet πŸ˜‚

@miklschmidt hey, I have a concern. After doing the "RatOS: Beacon calibration" the system did a restart. Was taking longer to start up and the bed was very very hot... like thermal run away hot. Am I missing something? I read something about this being an issue. I just don't know if there was a fix?

@miklschmidt https://keenovo.store/products/delixi-ssr-40a480vac-solid-state-relay-input-3v-32vdc-40da that is how I had it setup temporally. IF the RatOS installs or reboots after a config. in my case the PID heat bed saved settings and then rebooted. when that happens the heat bed is still heating until PI is booted up. In my case it hung up on boot. Now i've done it again with the tool head on Bed Mesh. It saved settings and hung while the hotend keep heating up the toolhead. Both times I had to do a complete shutdown.

@miklschmidt my wiring matches this https://os.ratrig.com/docs/boards/btt/octopus-pro-h723
BIGTREETECH Octopus Pro STM32H723 | RatOS
When the V1.0 version of this board boots into DFU mode (which happens during firmware updates), the heater pins on HE0 and HE2 will be set to high, meaning your hotend will heat up for the duration of the firmware update process.
miklschmidt
miklschmidtβ€’2mo ago
Side note: Make sure the SSR is switching the live wire and not the neutral.
in my case the PID heat bed saved settings and then rebooted
When you say rebooted, you mean klipper restarted? That's supposed to happen, i thought your pi rebooted which would've been really bad.
when that happens the heat bed is still heating until PI is booted up
So it did reboot!?
In my case it hung up on boot.
What? I need to see what's happening Please record it
It saved settings and hung while the hotend keep heating up the toolhead. Both times I had to do a complete shutdown.
How are you verifying that it keeps heating? and what do you mean it hangs?

@miklschmidt unless the power (line in) and bed has to be switched... that is the only thing I can see in question. @miklschmidt maybe the fuse itself.
miklschmidt
miklschmidtβ€’2mo ago
You're switching neutral, you need to switch L Sorry, that's not true, this is done correctly got confused πŸ˜‚ These IEC's are a bad idea with a 1200W bed on 110V. 1. The fuse they come with are usually 5A, nowhere near enough so they'll burn out. 2. The switch will short at the current you need and burn your plugs. The way you have it wired is exactly like the VC4 instructions btw, so that's good.
WOPR73
WOPR73β€’2mo ago
@miklschmidt So, It must be blowing the fuse due to the 5A
miklschmidt
miklschmidtβ€’2mo ago
yeah the bed itself will pull over 10A. Make sure your house wiring actually allows that. Typical american wall plugs are 10A IIRC. you need to make sure the circuit is on a 15A breaker as well Those 1200W beds were discontinued years ago because it was hard to run for americans. EU is spoiled with 220v mains
WOPR73
WOPR73β€’2mo ago
@miklschmidt yep, that 15A shouldn't be an issue. But, I will keep it in mind. The voltage and measurement difference really becomes a pain. The evil Imperial empire didn't do a good job at getting everyone to switch over.
miklschmidt
miklschmidtβ€’2mo ago
I'm still curious about the hangups and the continued heating etc you say you're experiencing, that should not happen. If you can show me what happens that would be very helpful.
WOPR73
WOPR73β€’2mo ago
@miklschmidt Well, I will give it another try once I get another fuse. I think that plug was repurposed from long ago and would like to get something that I know is made to connect to 15-20A vs 5A. Plus... I would like to look into getting Din rails and making things look nice and clean. I can change the wall outlet to be 15-20A GFCI and the breaker to be 15-20A.

@miklschmidt ok, no problem. I was trying to keep to updating only using the update manager in the RatOS
miklschmidt
miklschmidtβ€’2mo ago
Which normally works fine, not sure what happened here, but if your pi has lost power multiple times it's likely a corrupted filesystem They need to be shutdown properly before removing power
WOPR73
WOPR73β€’2mo ago
@miklschmidt I use the power in the RatOS to shutdown then power off. @miklschmidt I know i've used ssh into this pi. I can use 'sudo apt-get update'. But, when trying to use 'sudo apt-get upgrade' I get error 'E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.' @miklschmidt fixed @miklschmidt node.js versions are different. 18.20.5-1 vs 18.20.4-1 @miklschmidt node -v v18.20.5
miklschmidt
miklschmidtβ€’2mo ago
That's odd It means what it says pretty much, i refer to my previous warning about the lost power. you also said your system rebooted when you ran PID tuning And you've blown fuses etc So pi = dead in those cases? A reflash is properly not a bad idea if you have further issues, in case of filesystem corruption.
WOPR73
WOPR73β€’2mo ago
@miklschmidt Nope, pi is new. working fine. Do you think a clean install of RatOS would be worth doing? I have a new 32g SD

WOPR73
WOPR73β€’2mo ago
Connecting a 4028 fan | RatOS
4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.

WOPR73β€’2mo ago
@blacksmithforlife yep, I did it once already for part cooling. But, I need to add a second fan just like it.
blacksmithforlife
blacksmithforlifeβ€’2mo ago
The blue is the pwn and is how the fan is controlled Then use another always on fan port Or directly supply from a 12v PSU i.e. just need to supply it 12v somehow If I recall correctly, the octopus board has 2 always on fan ports. So the port next to the one in the image you showed should also work Double check by cross referencing your board's manual
WOPR73
WOPR73β€’2mo ago
@blacksmithforlife depending on which board, the type fan and which version of printer that you would be building. they change.. IE 3.1 vs 4.0 Ratrig shows many different ways to do this. none exactly matching.

WOPR73β€’2mo ago
@blacksmithforlife oh, I am not blaming anyone one. I am just telling you that things are not that easy for a new person to just jump right into understanding everything. @blacksmithforlife for example. I dont know if this 4028 is a 100HZ or 25KHZ. I have not been able to locate the information online as of yet. I just know that I have a hotend fan on 24/7 and dont know if it should or should not be. There isn't any reason to be on its not cooling anything down. But, maybe it's a safety feature. I dont know cause I am new and learning as I go. @blacksmithforlife I might have to just flip '!' but, it didnt work when I saved in in printer.cfg and did a restart.
blacksmithforlife
blacksmithforlifeβ€’2mo ago
Correct, server fans (which is what the 4028 is designed for) go to 100 per percent if the pwm is disconnected. So either your wiring is bad, it's connected to the wrong port because the config is telling it a different one, or the board's port is broken Yup, just imagine how it was before Rat-OS made it easier Be sure to look through other postings, many times it has been solved before for people

@miklschmidt so our conversation about the btt kraken let me to another thought. If we ran two steppers off one driver at 3.4a how would the driver respond since we are in the run current range you mentioned in the past that would make more sense and that would be shared between the two stepper motors…? Just ideas I’m brainstorming.
miklschmidt
miklschmidtβ€’2mo ago
It's better, but still not enough, you need twice that to avoid the currentscaler dropping below 0 on a 0.022 ohm sense resistor 2160. Furthermore you're introducing further current measurement inaccuracies since the two motors may not act identical due to production tolerances etc. Generally it should be avoided running multiple steppers on a single driver, there are only downsides if you have enough driver slots available to run them independently.

@miklschmidt I have ran "BEACON_RATOS_CALIBRATE" and works perfectly all directions X,Y and Z. But, the motors stay engaged after calibrate is completed and temps on the drivers continue increase to 90c. I am able to jogged the extruder manually to the left, right, forward and backwards correctly. But, jogging Z up and Z down are reversed when using the Toolhead controls. I am worry if I change it in the printer.cfg then wont the beacon calibrate be going the wrong direction and crash into the bed.

I chose to invert the up and down arrows in mainsail because logically to me the "up" arrow should make the bed go away from the toolhead but by default it is the other way around

Really? I press up and the bed moves away, and I didn't think i changed anything.
WOPR73
WOPR73β€’5w ago
@blacksmithforlife yes, if I press up the bed goes down, and if press down the bed goes up. But, "BEACON_RATOS_CALIBRATE" works how I would think it should. Moving the bed out of the way when untill needed to be checked for Z. then it bring the bed up and gets it reading then stops.

@blacksmithforlife are you sure that if I invert the Z's that it will not nose dive into my new bed when homing or running the beacon config. I understand that you say its mainsail and it very well might be, but I am to new to all of this to desern which is really mailsail vs klipper vs ratOS and which is going to effect the others.
blacksmithforlife
blacksmithforlifeβ€’5w ago
again, you should only invert z in mainsail interface after you have verified everything is working. Don't make your life harder
WOPR73
WOPR73β€’5w ago
@blacksmithforlife yep, understood. That's why I was asking for help. There is a lot of info on Z and motors going the wrong direction and how to fix it. But, there isnt alot on RatOS, Beacon, mainsail with properly running "BEACON_RATOS_CALIBRATE" but, an inverted Z.
miklschmidt
miklschmidtβ€’5w ago
That's the default mainsail behavior πŸ˜… up means "increase z"
WOPR73
WOPR73β€’5w ago
@miklschmidt yeah, I was reading that in "https://os.ratrig.com/docs/configuration/#initial-configuration"
Configuring RatOS | RatOS
RatOS only needs minimal configuration to work, but comes with a lot of optional functionality that you can enable manually.
miklschmidt
miklschmidtβ€’5w ago
Yeah so if you click the up button the bed should move down on a corexy printer with a moving bed like the V-Core. If it doesn't do that your z-steppers are inverted (but sounds like you fixed that)
Beacon, mainsail with properly running "BEACON_RATOS_CALIBRATE" but, an inverted Z.
You cannot run BEACON_RATOS_CALIBRATE with an inverted z, it would throw errors. As the bed would move away from the beacon when it's trying to probe it. So if the calibration went fine your Z is not inverted.
