Replace Y step motor solve Your problem?

I have a similar problem. After turning on Preasure Advance printer stopped directly after the purge line during the move to the first line of the print. Print crashe with “Internal error on command G1”

In klippy.log i found these errors:

> TMC ‘extruder’ reports GSTAT: 00000001 reset=1(Reset)  
> TMC ‘extruder’ reports GSTAT: 00000000

Moved to a new thread since most likely unrelated.

These are no errors but either the power up sequence or something that “healed” itself immediately.

Post your klippy.log

Interesting.  
Stepcompress errors **without** any preceding errors are quite rare.

Can you reproduce it? If yes, run a M112 immediately after the error and post the resulting log, please.

I can reproduce it in every print whit Preasure Advance is set. Without PA everything is ok.

Attached log include M112 immediately after firmware restart. Error shutdown firmware

@Sineos I do some tests and now I know what causes the G1 error, I think.

The problem is the combination of the PA and the pause at the end of my purge line at the end of the start script. If I set the PA, Klipper waits 2000ms after the purge line and raises an error G1. If I remove the “pause” line from the startup script, everythink is ok.

I have been using this startup script for about half a year and the printer is failing only now.

That’s odd. Can you attach the g-code file that causes the failure here?

Have you tried a `M400` just before the `G4 P2000` ?

I haven’t tried it. I don’t need it…  
If I need it, I’ll try the M400.

Thx for help

Thanks. I am able to reproduce this problem locally. This appears to be a regression introduced in the recent toolhead flush rework (for `pwm_tool`). The regression is introduced in commit c491ea66.

I will try to track down the root cause and a fix.

This should hopefully be fixed now (commit fe56bf36).
