Shifting Issue After Resuming APF in RRF

R006

@jay_s_uk
After upgrade to 3.5.0-rc4, i have facing shifting problem and some time Z is not it's correct position at printing time.

jay_s_uk

@R006 sounds like you have some mechanical issues on Z and you're potentially under powering your stepper motors.
But without knowing anything about your printer, its pretty hard to tell

R006

@jay_s_uk okay,

In Z axis we have use 3 leadscrew with 2stack stepper motor, in X & Y belt with stepper motor.

@luca-Massimiliano I'm not sure I understand your comment or how it applies to this thread

@jay_s_uk i am waiting for your response

jay_s_uk

@R006 response to what?

R006

@jay_s_uk shifting issue and Z position after resume APF
and Extruder heater fault

jay_s_uk

@R006 you've posted a single file with no other information about your machine, and expect me to diagnose your problem? And you've thrown in an extruder problem that you've never mentioned before and have again give no other details?
You'll be waiting a long time for any further response from me...

What exactly are you seeing for shifting in Y axis?

What do you have in your resurrection files?

How are you homing when resurrecting from power loss? How are you setting Z?

@R006 said in Shifting Issue After Resuming APF in RRF:

M98 P"0:\macros\SKEW.g"
M98 P"0:\macros\Backlash.g"
M98 P"0:\macros\ChangeSteps.g"

What do you have in those macros?

@R006 said in Shifting Issue After Resuming APF in RRF:

but extruder is not working.

What exactly do you mean?

It's very hard to understand exactly what is happening from your posts. Please be descriptive and share as much information as posible.

@Phaedrux :

I have one machine on Duet3. I flashed 3.5RC4. after this extruder motor holds the torque but does not move on extrude commands. When i go back to 3.4.6, it extrudes fine. looks similar to what she's reported. Mine is dual extruder.

Can anyone confirm that 3.5RC4 with their system:
a) drives dual extruder fine
b) Can you test Resume after power failure & check if it resumes fine & does not print from an offset. (for me it occurs in Y direction only).
This happens with Duet2 wifi based belt driven machine.

https://forum.duet3d.com/topic/35334/jerk-acceleration-value-change-after-resume-apf/10?_=1713269800841

c) Can anyone suggest a few checkpoints ?

JayT

@JayT :

This problem of extruder not working with Duet 3 is resolved after flashing RRF3.5.1.
Shifting problem remains same with Duet2, after resume on power failure.

R006

@R006
hello,
I have tested various versions of RepRapFirmware (RRF), including 3.4.6, 3.5.0rc4, and 3.5.1, in an effort to address the shifting problem. However, the issue remains unchanged across all versions.

To provide context, I operate a guide rod belt-driven system with Duet2 WiFi, which experiences shifting despite the use of different RRF versions.
1.shift in Y direction is more compare to X (most of the time shifting in Y direction with 0.2 to 1 mm).
2.also i have check homing sensor, distance of it is same for X & Y.

I also have a ball screw system with Duet3, and I have never faced similar shifting issues when using the same RRF(3.4.6, 3.5.0rc4, and 3.5.1) versions on this setup.

@R006 sounds like its a mechanical issue or you've set speed limits that are higher than your machine is capable of.
if it was a firmware issue, everyone would be affected
