Will need more tests and probably to install heat sinks on stepper chips (I already did install them past summer)

What causes those and what was the fix?

UM steppers (umo+, um2, um3) have a decay issue that makes that error (better explained on the forum link). This TL-Smooth fix it for just 8€.

Ofc this tl-Smooth is a china creation from a guy post without his consent, but on the good side they work and they are cheap.

Anyhow this requires more time test (to be safe) but I think this just works.

That's a pretty fascinating problem and solution...a very interesting read from the link (http://www.engineerination.com/2015/02/ ... steps.html) that Labern mentioned

Indeed I found the chips, labern dig deepeyand found that all the aliexpress seller key i fo comes from that guy development.

One could blame the china seller, but also the guy that found it never did anything with it. And for 8€ is a nice improvement for the umo/um2/um3 stepper chips

Can you show a bit more about how you installed them?

Hm, next week they are on sale on aliexpress, €6.51 for a set of 3. Might even order them, though I hardly print, and never noticed the problem what so ever. I'll check my old prints though.

@Neotko, you mentioned silent, that is a different solution path right? When I was printing again after a year the sound drove me nuts.

Indeed the 'silent' drivers it's other solution, for that you could move to a Duet3D board, or if you don't use PT100 maybe even a cheap Lerdge china, but so far this china nonopensource is quite basic, but ofc, it prints.
