TMC5160 suddenly shuts down during the print, sometimes not extruding after restart

[andrico21]

After latest update from GH my TMC5160 extruder began to fail during the print - mostly on the first layer after some successful extruding.
Also I've noticed sometimes the extruder not working right after Klipper/controller restart, but after manual initialization begin to work (but fail soon in the print process)

@andrico21
First point is that your stealthchop is very low on all motors. Theese drivers arent like 2130. You easily can set that to 200 on a corexy machine. Special mechanics ar impaction that in many ways.

So as a proposal try to use your extruder in spreadcycle first.

@Stephan3 thanks, I will try. I'm confused by the fact it worked great before latest update. No single successful print after update - sometimes extruder fail, sometimes leveling is not working

[andrico21]

Okay, I digged into 'git reflog --date=iso | grep pull' output: previous update I performed at 2019-06-23 16:31 +0100 (which was c3467f5). So the potential "problem" commit was between 2019-06-23 and 2019-07-09.
Now I'm on 0f1d424

Can confirm now - extruder is not shutting down after resetting to c3467f5 commit

I got the same problem sometimes a motor switches off.

Edit: added klippy.log Z-; and Z1-Motors were switching off.

There weren't any significant changes to the TMC code between c3467f5 and 0f1d424. My best guess is that the driver didn't receive some of the init messages - possibly due to a motor power on race, or due to noise on the spi line. You might want to try sending DUMP_TMC commands to inspect the state of the driver after power up and after the failure.

@KevinOConnor please check my log in the thread first message please - I've dumped TMC registers several times there and after extruder fail I tried to init TMCs manually and then the extruder worked fine - TMC dump after is also there.

I'm using 0.9° steppers and I lowered the microsteps from 16 to 8 now they're also working as intended...

[andrico21]

@Oranginator I'm also using 0.9° for extruder, but bandwidth is enough

[KevinOConnor]

Alas, I don't have any insight to the cause of this issue. The best I can offer is that if you (or someone else) can diagnose the root cause of the issue, then I may be able to help with a solution.

If you can obtain and annotate a DUMP_TMC before and after a failure, that may help narrow down the issue.

@andrico21 Have a look at #1774. It outlines how to debug this issue and it's root cause might be relevant here, too.

[andrico21]

@lekv thanks mate, I'll check GCONF state in next 2-3 days.

[KevinOConnor]

Any further updates on this?

-Kevin

[Oranginator]

I don't know how but mine is working fine atm.

[KevinOConnor]

I'm going to close this issue as it appears the conversation has concluded.
