still cant get first layers to be consistent

i'm at my wits end with this printer. im 10 days in and still dont have a first print done. i've been tryin to get my first layer issues sorted out. multiple beacon calibrations later, i'm still getting inconsistencies and non-sticking portions of prints. it's not the build plate, it's clean. the printer is not putting the plastic down close enough to the bed to smush on the external walls, it's constantly all over the place. it's exceedingly frustrating. this printer was supposed to be up and making molds a week ago. i need help

Ok. So post your printer.cfg

CrashTestCharlie / VC4 400h
Ok, nothing wacky. So hers what I'd do, Run the configurator, and let it wipe out the printer.cf, then delete all the save config stuff at the bottom Only add back in the bare minimum, like motor direction. Just what in needs to work, nothing else Rerun beacon_ratos_calibrate Then try the first layer stl again
Rewire
RewireOPโ€ข2mo ago
That's what happens is the first layer STL always comes out fine it's subsequent prints after that that are the problem I get one good first layer per calibration
CrashTestCharlie / VC4 400h
Ok. Have you tried printing the first layer stl then turning it off. Then printing again after rebooting? Then you'll know if it's a setting getting lost or not

so i cleared my config agaign tos tart from scratch and nwo can't get ratos to calibrate again. something is seriously wrong when it does the poke test with a 150c hotend + warmed bed in the middle of the calibration. every time it does the poke test, it varies by .03, within variance amounts, so it fails the poke test. almost like the z motors are skipping the same amount of steps, when the hotend is at a specific temp, in the middle of calibration. wth? problem doesnt occur when the hot end is at 250c during the calibration

Double check all three if you haven't done them even if you're confident Your mesh is good and doesn't show any signs of gantry twist but your values do so something is not correct. Since the mesh is done without Z movement I'm thinking you have issues on Z

Is the coupler supposed to align with the flat part of the motor shaft somehow I don't remember that in the guide All I remember is is it saying to tighten the coupler while pressing down on it i took them all off and aligned the line of the coupler with the flat part of the motor shaft, and the screws are in so tight that im afraid ill strip them, so going to try again... the thrust washers all stuck to the bottom of the coupler when i took them off the motor shaft, so i dont think that was it

The slack in vertical direction is expected and not an issue. Gravity is your friend here ๐Ÿ™‚ Probably not the cause here, but I had a similar issue when my bed had tiny bit of plastic at the home position. Perhaps try moving the build plate a few mm and see whether the variance continues?
Rewire
RewireOPโ€ข2mo ago
bed looks super clean, so i dont think that's it, but i appreciate the suggeestion i'm not sure what else to tighten, i've got my torque screwdriver maxed out (30 nm) on every screw related to the Z unless im supposed to be making these pillow blocks deform. Oh, and the screws that hold the printed parts to the rails. im afraid ill break those cause it feels like i'm deforming the plastic

the only possible thing i can think that is happening is the lead screws are slipping down inside the coupler, and i need to make some sort of insert, but i dont have anyting that's non-compressable to put in there i guess i could put some small washers in there. i greased the lead screws (when i first assembled, they were squeaking bad), squeaking went away, but when i undid the couplers, i can see some grease inside the coupler so if the metal is not deforming and is holding with friction only, they might be slightly slipping
CrashTestCharlie / VC4 400h
Def something mechanical to make it change that much on just a small z move
Rewire
RewireOPโ€ข2mo ago
i just have no clue what else to tighten, if i tighten anything else the screws or parts are going to break, the only thing i can think of is something slipping i rounded off one of my 2.5mm allenkeys tightening things i mean they are cranked
CrashTestCharlie / VC4 400h
Yeah, what I circled is it not going back up the sane amount as it goes down.
Rewire
RewireOPโ€ข2mo ago
yeah
CrashTestCharlie / VC4 400h
The screw can be tight but that doesn't mean it's clamping tight.
Rewire
RewireOPโ€ข2mo ago
it would take a lot of calibrations for the lead screws to bottom out, but the guide says "don't let them touch the motor shaft" imma take off the couplers and put some washers in the big part where the lead screw goes and let them bottom out on those so they can't drop further
CrashTestCharlie / VC4 400h
Taking the couplers out is a good idea Put something in the slot, then put on motor, the put in lead screw , then remove the spacer. That should give enough clearance
Rewire
RewireOPโ€ข2mo ago
gotta find something thin enough
CrashTestCharlie / VC4 400h
Some scraped first layers should work :kekw:
Rewire
RewireOPโ€ข2mo ago
So i'm hoping this will solve it. 1. I'm printing a PC material key for the z motor shafts to go into the coupler, to lock their rotation with the coupler. 2. I'm printing a TPU washer to allow the lead screws to bottom out in the coupler while removing them from the vibrations of the motor, which is why I assume they say "don't let the lead screw touch the motor shaft". ok well the z-tilts arent' changing much after cleaning and reseating the pei sheet and doing a few of them no having to re-do tolerance so here is hoping
Rewire
RewireOPโ€ข2mo ago
No description
Rewire
RewireOPโ€ข2mo ago
nope. the couplers are bottomed out on the tpu mounts i made, the lead screws can't go any farther down so i guess i must try to do something with the toolhead then
Helge Keck
Helge Keckโ€ข2mo ago
TPU mounts?
Rewire
RewireOPโ€ข2mo ago
i made these to put in between the motor shaft and the bottom of the lead screws, so instead of them "floating" (and slipping down when doing poke tests, which I thought was my problem), they physically cannot go down further

Helge Keck
Helge Keckโ€ข2mo ago
what do you mean with slipping down?

I thought that because my lead screws were greased, they were slipping in the coupler, leading to my failed poke tests and the large variations pointed out in this

unfortunately it seems my problem lies elsewhere the big variations only happen when the bed is at 85 C, idk if that tells you anything

SSR is cheap and easy to replace. I would begin there Still i think it would be interesting to see how your cold bed mesh look like when using beacon contact instead of scan Then you are moving Z but SSR is not involved Compare scan and contact with SSR off It's a simple variable

redid all the linear rails and re-squared the frame this morning, failed again with interestingly similar poke variances, crazy how it gets the first poke done, then the second one is out of variance, so it re-tries and gets very similar numbers. i went and checked where it failed and it was the same location on X where it has failed in the past, and those screws on the linear rail seemed loose, so i tightened them, before the toolhead when moved manually almost seemed like it "slipped" when it went across that area, there was much less resistance compared to the rest of the rail, after tightening the 2 screws close to that location the x rail it seems to have similar resistance to the rest of the x gantry, so trying again

Yeah so, this is not fixed. I started having issues again last night, and now i can't get a good first layer again. Having to start over from scratch again. Printer just forgets settings or something. Z-offset is constantly changing. I am jealous of anyone that built their printer and got it printing in less than a few hours or whatever. I'm 15 days deep and regretting my purchase. Can't print anything. Spent all day yesterday trying to get decent prints out, bunch of filament bs, now I'm back to bad first layers.

I've honestly never had problem like this ever, before my X1C, I had a taz 6, before that a MP select pro, and before that a ender. I've got no clue where to get started. I've never had any issues like what's going on here with my v4

miklschmidtโ€ข2mo ago
This could be missing (or not properly sized) PTFE tube between extruder and hotend, bad extruder tension, completely borked PA settings, wrong thermistor configuration, bigger nozzle than sliced for etc etc. Is your nozzle properly hot tightened? Have you checked if there are any leaks from the hotend etc?
Rewire
RewireOPโ€ข2mo ago
The PTFE is the one that was provided, i've got the 2.5mm ptfe from the kit, i've not done anything with PA, i'm pretty sure my thermistor is set up correctly (i followed the guide), and my nozzle is set to 0.6 in both the slicer and firmware the only thing i'm not "sure" about is the ratos setup defaults to CHT nozzle when you select the .6, and im pretty sure it's a "regular" nozzle, with one hole, not 3 my cold pulls look perfect, so i dont think it's a nozzle issue or leaks

I don't mean the ID/OD of your reverse bowden, i mean the length of it between the hotend and the extruder. It should fit very snuggly in there and you should chamfer the ends. The piece between your extruder and hotend should NOT be a 2.5mm ID tube

Good, sounded like you used the 2.5mm ID one for a second ๐Ÿ˜„ It's prolly worth checking yeah.
Helge Keck
Helge Keckโ€ข2mo ago
if you put the extruder on top of the ptfe tube, there shoul dstill be a o.5mm gap between extruder and top plate, this makes sure the ptfe tube isnt too short a tiny bit of comrpession is fine and desired

i just want a printer that prints and it's really depressing that despite following the guide, my printer doesnt print for over 2 weeks now. it's never printed anyways. i'm going to try and heat soak and then ratos calibrate and see if i can get decent first layers again....

Just wait till you find the cause and it turns out to be some silly stupid mistake. This is part of the DIY experience.

like why does my z-tilt always need to be adjusted, is that normal?
miklschmidt
miklschmidtโ€ข2mo ago
What do you mean by "always need to be adjusted" exactly?
blacksmithforlife
blacksmithforlifeโ€ข2mo ago
because after a print the steppers are turned off, thus losing their position. That's why each print you need to redo z-tilt. It is normal
miklschmidt
miklschmidtโ€ข2mo ago
it always runs, and yes that is on purpose. When the motors power off they lose positioning and default to the closest full step position. That's how steppers work
Rewire
RewireOPโ€ข2mo ago
ok gotta get my kid ready for school....have to come back to this.... going to try and ratos calibrate with the heat soak in the meantime....
miklschmidt
miklschmidtโ€ข2mo ago
I'm pretty sure you're chasing the wrong rabbit here. This symptom of the first sample being way off from the second is pretty common though, so much so that there's often a "SAMPLES_DROP" option to discard the first (or more) samples when probing.
Rewire
RewireOPโ€ข2mo ago
how do i turn that on
miklschmidt
miklschmidtโ€ข2mo ago
That's news to me.. It should not change your nozzle type when you change the nozzle diameter. I would also STRONGLY recommend you start with a 0.4mm nozzle. 0.6mm are harder to tune, and much easier to fuck up as everything defaults to 0.4 (slicers, guides etc). it shouldn't be necessary at the speeds the calibration runs at. You can't "turn it on" without modifying the macros. Also @Rewire have you updated all the packages? Can't find any message from you about software updates.
Rewire
RewireOPโ€ข2mo ago
Yes, always am on the latest versions, first thing I do before I start doing anything with the printer every day only reason i wanted to do 0.6 was to get larger prints out faster higher layer heights and all that, i bought this to make large molds, so i'll have to post-process them anyways
Rewire

miklschmidt
miklschmidtโ€ข2mo ago
This is just super random and not a "first sample is off" thing. Z axis looks unreliable Perfectly valid, however it'll be much easier to swap in a 0.6 once you've got everything working properly.
Rewire
RewireOPโ€ข2mo ago
Not sure how to fix short of replacing all the Z axis parts, none of them are loose, I know cause I've gone over them about 20 times now My rails were like butter so I don't think that's it Some of my lead screws are visibly wobbly but the sliding screw (old man hands?) inserts should fix that right
blacksmithforlife
blacksmithforlifeโ€ข2mo ago
How wobbly?
Rewire
RewireOPโ€ข2mo ago
I'll see if I can get a video when I get home
miklschmidt
miklschmidtโ€ข2mo ago
You're sure it's not just a dirty nozzle or oozing? Nozzle that needs to be hottightened? something like that? Is there any play in your hotend assembly?
Rewire
RewireOPโ€ข2mo ago
no filament in the nozzle, always do a cold pull before trying calibration it was doing this long before i ever got filament in the machine it might be the x carriage, but i dont know how to test that there's no loose screws, that im confident of
miklschmidt
miklschmidtโ€ข2mo ago
Just noticed the gantry here, i can pretty much guarantee you'd get better results with a 2020. It looks like it has the rigidity of a wet noodle. If you grab the nozzle and give it a wiggle (up/down side to side etc), is there any play?
Rewire
RewireOPโ€ข2mo ago
it's the spannsystems, i thought that might be it, but let me try wiggling the nozzle ok....it's somthing with the toolhead or the toolhead carriage side to side nothing, but up down, it's moving a bit, but if i put my hand on the gantry, that's not moving so it's the carriage or something related to that
miklschmidt
miklschmidtโ€ข2mo ago
At least something to look into!
Rewire
RewireOPโ€ข2mo ago
but i can't fix that besides replacing the carriage, right? i mean, i have the extra one meant for idex....
miklschmidt
miklschmidtโ€ข2mo ago
You don't even know what's moving yet If you want my recommendation, remove the flimsy tube, put the 2020 in This could easily be a case of premature modding, and that design from spannsysteme is one of the worse ones i've seen All rigidity lost
Rewire
RewireOPโ€ข2mo ago
I can try swapping it out wanna see if there's something up with the carriage first, will have to look later tonight
archen
archenโ€ข2mo ago
Why would you even use the spannsystem tube. What's the benifits? Ti tube fine but that tube still in alu makes no sense at all, I'm all with mikl, remove that tube.
miklschmidt
miklschmidtโ€ข2mo ago
People do it to lose weight, because they believe it'll make their input shaper numbers go up, which it does by a couple hundred points, but it also results in significantly worse print quality because it's so flimsy. They can be a very decent upgrade if done right (no loss of rigidity and tortional stiffness), but it's a minimal gain. Get a poorly designed tube like this one (sorry if i'm offending anyone, but i'm tired of these, it's lazy and a bit of a money grab) and it's a straight downgrade. The Toro TI tube is pretty sweet, i agree.
Helge Keck
Helge Keckโ€ข2mo ago
imo the little inout shaper gain you get from such tubes isnt worth the money at all. barely noticeable in daily printing. only helpful if you want to push the printer to the absolute limit
miklschmidt
miklschmidtโ€ข2mo ago
People need to understand that max recommended accel != max accel.
Helge Keck
Helge Keckโ€ข2mo ago
yep if there would be a graph that shows money per performance, nothing will ever beat a cheap alu extrusion but i can understand why people are trying it, modding a printer is fun

first printer like this, thought the mod would amp up my speeds, but it's redundant if i can't even print in the frist place lol gonna see if the carriage is the issue, but probably going to take it out and return it same reason i went for 48V and had to buy new power supplies, speed, but then that led to software issues helge helped me sort out plus the mirrored stepper driver plug issue
Helge Keck
Helge Keckโ€ข2mo ago
it does ramp up your max accel a tiny bit, but thats only for the outer perimeters, for the rest of the print you can go full blast anyway. so the final print time doesnt really change

at this point, i just want a print, at all lol

Sorry I'm a little bit confused on what you mean by this It sits flush against the tool head plate The way I've done it is I push the PTFE tube all the way down into the hot end and then put the extruder on top of it
Helge Keck
Helge Keckโ€ข2mo ago
this could probably mean that the ptfe tube can be too short when putting the extruder on top of the ptfe tube, there shoul dbe a izzy bizzy tiny gap between extruder and top plate, like 0.3 mm or so

48V is a worthwhile straight upgrade with no downsides though! All it does is double your max velocity at full torque however, but that's really nice for travel moves. I feel this, been there so many times ๐Ÿ˜‚

most people come to the same conclusion

miklschmidtโ€ข2mo ago
This is extremely common and tends to be perpetuated by some speed focused youtubers and other types influencers in the space. It's an easy mistake to make, don't blame yourself. However i sorta blame Spannsysteme for making these things with no testing.

I am curious if my thermistor is off or something, that benchy was printed at 265 for PETG....i have the jumper in the sbb42 and the setting in ratos pt1000 but i was having issues with 240-250 just not enough melt and slower than my x1c, but PID tune says it's correct gonna charge my thermal camera and check....
archen
archenโ€ข2mo ago
I'm printing PETG at 260. Don't compare temps with other hotends Do a temptower
Rewire
RewireOPโ€ข2mo ago
is it cause of the long melt zone? rapido long af
archen
archenโ€ข2mo ago
I would say its probably mostly because how the temp is measured That's why you need to do temp towers and not copy others settings
Rewire
RewireOPโ€ข2mo ago
i see i see
archen
archenโ€ข2mo ago
I usually start of with a temp tower. Then flow
CrashTestCharlie / VC4 400h
You using the .0"6 black nozzle? It's steel, takes more oomph to get the heat to the plastic. So your temps would trend high
miklschmidt
miklschmidtโ€ข2mo ago
indeed, needing an extra 10-15 degrees is common with hardened steel nozzles, and they do impact flow rate. That's why you see people preferring tungsten carbide nozzles or Bondtech's bi-metal cht nozzles. It's worse on the Rapido 2 as the thermistor placement and exposure to the outside is really not ideal. That issue has been fixed in the Rapido ACE as well as the Rapido 2F the ACE is superior to the 2F though

Crap,.... just installed the Rapido 2,... need to upgrade again? Rapido 2 UHF is getting superspeed, dispites it short comings ๐Ÿ˜‰
miklschmidt
miklschmidtโ€ข2mo ago
No it's still a pretty great hotend despite it's flaws, nothing is perfect ๐Ÿ™‚
CrashTestCharlie / VC4 400h
Is there measurements for the load/unload macros for the ace yet?

I havent swapped too much but so far I just use RatOS defaults. for rapido uhf
Arthur_C
Arthur_Cโ€ข2mo ago
The ACE is a couple of mm shorter, I thought. Probably good enough for a drop in replacement or do you use some washers to compensate that, @Mitsuma?
Mitsuma
Mitsumaโ€ข2mo ago
it comes with a 3mm spacer you put on top, you need longer M2.5 screws, 8mm instead of 6mm tho
miklschmidt
miklschmidtโ€ข2mo ago
klipper will do that automatically when you run pid calibration and save it exactly
