Chonk needs coding for 3 axis Z-tilt
Hello guys I was hoping the Chonk builds could receive the option for z-tilt bed leveling. With a toolboard the skrat has the open slot.
ZMA= Z0 E0M= Z1 E1M=Z2 just like a V-core. This would be nice to have. Is this possible?

Did you pick skrat in the configurator?
yes
However there's currently no available 3z chonk printer config.
Wouldn't take long to make one though
Please please please you would make this printer better!!!!!! I can run tests for you as I have one ready
I have the normal build at the moment. I run a toolboard and have the extra slot open. Its like a mini me to my V-core 3.1 500.
I have an ebb42 on it currently but I just ordered the Orbiter Orbitool. We are mounting the toolboards on the motor and retaining the stock clearance now with the open port which would mimic a V-core and add to the build.
A few minutes of work.
It will be enough to add a few lines to printer.cfg.
I haven't tried, I don't have such a board, nor 3 motors on Z.
hold my beer
@DJDupid done and pushed 🙂
I've just limited the Y to 170, as i wasn't sure if 180 would cause toolboard damage, IIRC it doesn't quite fit.
Awesome!!! No need to limit to 170 as we have full travel
With a toolboard? are you sure?
plenty of room
So I just need to move the ZMB stepper motor to the E1M slot reconfigure right?
guess it was fixed, i'll put 180 back in
yep
(you need to select the V-Chonk 3Z printer)
Update is on the way
give it 10 minutes and it should be ready 🙂 (you need to update both RatOS and RatOS-configurator)
I am not using the earlier ebb mount that people were having clearance issues with. I did spread the word in the Chonk section to mount the sensor on the motor. I have an ebb36 and ebb42 mount I will upload
currently I am installing the orbitool toolboard so give me an hour or two on that.
The height on that thing and the 2 point mounting looks like a resonance nightmare.. Chonk toolhead really isn't made for toolboards, lol. I think i'd rather slap a 6 driver board in the bottom but in any case, it should work. It's gonna be a problem for people who use the other mount... Now i want to limit it to 170 again.
its pretty compact compared to the ebb42
I have reflashed the SD card twice to reconfigure and keep getting this error code. It also keeps telling me my pi is on an older version and when I click flash board it just keeps cycling back to this message
It finally let me update everything and I did the config for the beta z but now get this error. I haven't shut it off without properly hitting shut down in klipper just so you know.
You're missing strain relief. Which is what makes it so damn tall.
This is an old version
Are you sure you updated everything?
I have reflashed the SD card twice to reconfigureYou need to update everything after connecting to wifi before proceeding with configuration This was alread fixed.. hmm
what should I do?
taking a look at the debug zip now
@DJDupid try :
I think the problem is because of the
max_power: 0.995 and software pwm. In shutdown mode no software is running and it defaults to 1 on heater_fans (for good reason) which gets limited to 0.995, which then triggers the error.
I have pushed that fix now so you can just update instead 🙂I updated and got the same error. I then went and cleared out my SD card. Flashed the image again. Set up wifi. Did all the updates. Then I ran the configurator. Same error.
This error started when I installed the orbitool. When I had the normal config and the ebb42 this error never came up.
There’s no reason for all the reflashing.
It’s caused by all the max_power: 0.995 requirements on the orbitool O2. You prolly need hardware_pwm for more than the toolhead cooling fan i gyess
Is that something you select in the settings?
No you write that in printer.cfg in the user overrides like i showed above https://discord.com/channels/582187371529764864/1298757434801786890/1299482753783435344
Oh I thought that was part of what you pushed through in the update yesterday
I dont know if I did this part right as the error is still there.
Instead of .995 can't we just put 1 like the error is asking for?
Only for the heater fan, not the rest of them
This is indeed already in the config. [fan] and [extruder] isn't.
If you put 1.0 in max_power it causes issues with the protection features on the orbiter o2 (that's the reason it's there, it's from the original config).
so what should I do here I am confused?
I'm assuming [fan] is enough.
remove the extruder part, like i said, pretty sure [fan] is enough
ok I removed the extruder part and now this is the error
reflash your toolboard it's (very) out of date
Ive reflashed it a bunch
it just cycles back
You need to flash it with manual dfu
The orbitool o2 doesn't have a bootloader
So @DJDupid there's no way around setting shutdown_value: 0.0 on the heater_fan unfortunately, which is not great in case of thermal runaway or shutdown with a heated hotend.
Remove your overrides and update and it should stop complaining about PWM_MAX.
I updated with dfu and it worked for the flashing. I removed the overrides and updated ratos and the configurator updates I see too. A new error now
jesus christ, i'm on a roll today 😂 sorry! gimme a sec!
Fixed, update again 🙂
Do I need to reflash the toolhead too? The other error is back
I clicked update for both ratos and the configurator then the error changed back to the old one as you see
Yes you need to flash your toolboard, it's old af. Needs to be done via manual DFU as i wrote earlier: https://discord.com/channels/582187371529764864/1298757434801786890/1300053558326198303
unless you laredy did that
Not sure where this is coming from
Solution
try adding
back into printer.cfg
That worked!!!!!
homing fails though
My pinda is triggered full time at the moment and the nozzle ran right into the bed
We are getting close though!!!
? .. It won't move if it's constantly triggered. Please be careful when you're wiring and testing things for the first time, always be ready to hit the emergency stop.
How did you wire it?
there's no wiring diagram
Your probe's signal pin should go here
5V (brown) goes to pin 2 on that header, Gnd (Blue) goes to pin 4.
I have brown on two, blue on one, black on 5
Black was Servo on the Ebb so I matched
so move one to four but should I leave black at five?
I got it working. Brown to two, black to three, and blue to four
yeah servo is the pin that's used to move the bltouch pin up and down, so that's why it didn't work for you.
