RRF v3.3/Mini 5+ Wifi - Major problems with layer shifting

T3P3Tony

@gixxerfast I can feel the lead screws on my z motors moving slightly if mesh compensation is working. Also what does DWC report for mesh compensation?

Looking at the files you shared the print_start.g has a lot going on in it. Potentially interesting are your bed.g (as you run that) and this M98 P"/macros/autoz/autoz.g"

Other thoughts: For the parts where you have the layers squashed as you have shown and the layer shifts, are they still the correct Z height across the whole part?

As there is a lot of different things going on here I would like to simplify things down to the bare minimum. I can propose a couple of tests to help isolate what the issue is

create a cube test that recreates the problem so you have a quick print. An example coupld be a 30x30x30 print (not that complicated test print, just a simple cube) placed in one corner of the bed,
once you have a quick reproducible issue, try the same print with mesh compensation turned off. You will probably need a with a larger first layer height and ( maybe will not get a not perfect first layer). Don't use your print-start.g at all and edit the start gcode of your test file to remove all references to things that effect bed levelling or mesh compensation.

Depending on how out of level your bed is you will need to be close to the emergency stop if its really out of level. If it is then you may need to run G32 manually before starting the print.

The idea is to see if its mesh bed levelling or something else causing the issues.

@gixxerfast I understand the Vorons are all CoreXY machines. Are the layer shifts always along one diagonal, the same one each time? If so then it suggests that the motor isn't providing enough torque. Possible reasons include:

Bad crimp in the cable connecting the motor to the driver
Motor current accidentally set too low for that driver. Send M906 without parameters during printing, to confirm that the motor currents are correct, and send M913 to confirm that the current is 100% of that value.
Loose grub screw on motor pulley
Mechanical issue with that belt/pulley system
Running the driver in stealthChop mode without executing the proper tuning move during homing. You can use M569 P# D2 to force spreadCycle mode (where # is the driver number), to see if this might be the problem - do this for both XY motors. Note, in stealthChop mode the drive is less able to respond to sudden increases in load, such as when hitting a filament blob or curl-up.
Bad driver. Try swapping the X and Y motor connections over on the Duet, and swap X and Y in your M584 command. If the problem moves to the other diagonal, it's a bad driver.

T3P3Tony

@gixxerfast so you now have two approaches - looking at the XY motion as @dc42 suggested to ensure that is right, and then looking at Z as I suggested.

I did not think it was XY at first because the layers looked squished in the pictures however it is worth checking to eliminate that as an issue.

@t3p3tony
Big, thanks for helping with this problem.

I will do as you say and try that.

Given that what's said above about motor current and if with a max motor current of 1.68A that a m906 current of 1.2A is OK, then I'll try that first

The prints are dimensionally accurate in z overall.

The autoz macro is calculation a correction factor between the Z-pin and the bed height and then adjusts the baby-steps.
The value it determines varies by how warm the chamber is and how long it has been warm. The last print it determined the baby step value to -0.08 mm.

I can post it later. The bed.g macro is just a standard four point quad gantry leveling.

@dc42 said in RRF v3.3/Mini 5+ Wifi - Major problems with layer shifting:

You can use M569 P# D2 to force spreadCycle mode

Thanks DC, I was going to ask about this I don't want to run in stealthchop anyway.

Looking at the failed prints it seems like they shift in a diagonal fashion.

I will up the motor currents, make sure that stealtchchop is disabled and also do the testprints as Tony suggested.

I will have to do that tonight and I will report back the results.

Thanks again all

Im really starting to almost give up here.

No matter what I do, I still have layer shifts with this print.

I don't know what to do next. Almost printed a spool of ASA in failed test prints.

What can I do next, any tips please?

I don't want to revert to the old setup as that's a ton of work as I now have a can toolhead board and umbilical instead of cable chains.

I have recrimped and checked the X motor connector as all layer shifts, shifts to the down(-y)/left(-x)
Using driver 2 instead of driver 0.
I have changed the thermistor setting
Increased printing temperature
Removed all macro calls (almost) from config.g
No bed mesh, no auto-z
Forcing into spreadcycle with a m569 P## D2 for all motors

First layer is good, extrusion is good to OK depending on temp.
Stepper motors are about 60C after print.

With Klipper I was running 800/700mA on the A/B-motors and max 5000 mm/s2 acceleration without any problems:

kinematics: corexy
max_velocity: 300  
max_accel: 5000    			#Max 4000
#max_accel_to_decel: 3000
##max_accel: 7000    			#Resonance test - remove after test
##max_accel_to_decel: 7000    #Resonance test - remove after test 
max_z_velocity: 20 			#Max 15 for 12V TMC Drivers, can increase for 24V
max_z_accel: 350
square_corner_velocity: 5.0

Now I request only 3000 mm/s2 printing acceleration and 5000 transport acceleration. Is this too much for RRF/Duet and my motors, must I lower this?

I printed the 30mm cubes in the corners with mesh and all macros and they printed without problems, but as soon as I try even a single part of the problem print above. I have layer shifts.

The motor harness is a factory crimped harness from Fermio Labs which I've had since I built the printer.

Btw, I use SuperSlicer 2.3.56

Btw, this is marked as solved but I can't see any solutions in there. (it's a long thread so I could have missed it)

https://forum.duet3d.com/topic/22436/missing-steps-cant-print-spreadcycle-stealthchop-tuning-help

Seems like I am in the same boat...

@gixxerfast

I got four printers running RRF v3.3 and two of them are using Mini 5+ boards.

Layer shift is not a problem.

So its not a fundamental RRF or Duet problem.

Which leaves us with something about your hardware, your configuration or some of each.

If you post your files using the </> tag it makes it easy for anyone to take a look, as opposed to having to download and open in some editor.

@fcwilt Hi, yes I don't think there's a general problem with the mini5+

~~BUT, reading from and talking with quite a few, there's seem to be a problem with 0.9 steppers and the mini5+(TMC2209) / rrf.~~

Do you run 0.9 degrees stepper motors+

No except for one extruder.

Does it appear to be a hardware or firmware compatibility problem with the Mini 5+ and 0.9 steppers?

@fcwilt I should actually amend my comment. It could be old topics. So I really don't know and shouldn't make such statements.

It's getting late I might have to edit this a bit tomorrow

@gixxerfast I get your frustration! especially with those long prints. What we need to work out is what is the root cause of the layer shifts, is it:
a) the print head knocking on the print so there is in issue with Z motion of some sort or
b) the XY motion.

Initially I went down the rabbit hole of Z motion due to the mentions of mesh bed levelling being in question, you mentioned the nozzle grinding on the prints, and at least one image looked like squashed layers. I now am not sure about that because of:

@gixxerfast said in RRF v3.3/Mini 5+ Wifi - Major problems with layer shifting:

all layer shifts, shifts to the down(-y)/left(-x)

As you have already pointed out that indicates something with the XY motion, not Z. You have also checked the connector, are confident about the wiring and tried a different driver which eliminates quite a few possibilities also the fact you only see it on the more complex prints makes some causes less likely.

From the look of your new pictures the layer shifts are cumulative, always in the one direction?

I know you have already swapped X from D0 to D2 without resolving the problem. Can you try the following:

Swap the X and Y drivers and motor cables and see if the issue stays the same place or changes to layer shifts in the opposite direction

M584 X0.1 Y0.0 Z0.3:0.4:0.5:0.6 E121.0

I have used the driver 0 for the swap here but you can use driver 2 as you currently have it configured if you prefer. The idea is that you change Y and X, not just X.

When/if the layer shifts are happening please do the following:

Send M906 and M913 with no parameters and confirm that the currents are as expected and at 100%.
Send M569 P1 and M569 P0 (or P2 if you are using driver 2) and posts the results here.
Send M122 and post the results here.

Hi, thanks for the reply even on a saturday

I'm in the middle of testing again, but I haven't switched the cables as you suggested just yet as it requires a bit of printer disassembly (quite a bit). I will do it later.

However, I'm starting to wonder if I have beed barking up the wrong tree. With a corexy, if it shifts to -x/-y couldn't that suggest that it's the A-motor (y-motor right one) that is skipping steps when trying to do a non-diagonal move?

Is this something to worry about, btw?

T3P3Tony

@gixxerfast I will have to get @dc42 's opinion on the failedOp 0x01 error.

mrehorstdmd

@gixxerfast Z axis jerk (1 mm/sec) and acceleration (250 mm/sec^2) seem awfully low to me. Maybe the nozzle is dragging on the print when the layer changes or when you use lift on retract...

Gixxerfast

@t3p3tony

Latest shift after z 5mm. Going to check y-motor, crimps and switch driver for that.

Need to get myself an easier testprint.

Cable switching is after that. (The y-motor cable is shorter than the x-motor cable)

Hmm, it's all stolen from allegedly working setups:-)

; Sets normal speeds and acceleration for printing operation

M566 X600 Y600 Z60 E8000        ; Set maximum instantaneous speed changes (mm/min) aka Jerk
M203 X12000 Y12000 Z3000 E15000 ; Set maximum speeds (mm/min)

M204 P3000 T4000                ; Set printing acceleration and travel accelerations

I'll recheck those. I have a belted z and four z-motors so fast z-movements shouldn't be a problem. DO you have a suggestion?

I could up the z-acc to my old Klipper-value which was 350 mm/s2. I have no idea what a good jerk value would be.

Gixxerfast

@t3p3tony

Well, shifted A cables to B-motor and vice versa. And reconfigured th emotor assignment as described.

But no, same thing. It shifted in the same direction.

So I made a descision to change motors to 1.8 degr OMC motors. It seems like I just can't get it to work with the LDO 0.9 degr steppers.

Anyway, I'm posting the output so that anyone that wants can maybe find out what's not working.
Here's the output from before the shifted print

EDIT: I almost forgot. I'm an ungrateful git. Big thanks to everyone that has helped trying to pinpoint the problem.

Finally! Swapped out the Voron branded 0.9 LDO 42STH40-2004MAC with the OMC 17HS19-2004S1 1.8 degr motors and YES it comes out as it should. Btw, all grub screws and pullies were rock solid. The belts ran super smooth and was even and the gantry wasn't racked but super square

I removed all drive mod config (D2 etc..) and just ran it vanilla.

Much more silent as well

Conclusion (I hope), must be after 20 something failed prints that either this setup just doesn't work with these 0.9 degr stepper motors unless you configure it some way unknown to me or I have faulty motors. Then again I came from a fast working setup where I regulary printed with 5000+ acceleration with these.

I just don't know. I just hope this is history for me now

I had this problem a few months ago. To fix it I had to replace the Y stepper motor. It was apparently missing steps many steps then starting up again. I suppose it could have been a connector but I used the same connector on the new motor and had no issues after that.
