Extruder stops working near the end (Linear Adv is off) #28

Closed willmackey2nd closed 3 years ago

willmackey2nd commented 3 years ago

Description

Extruder motor stops near the end of the print when there's fine details

Steps to Reproduce

Noticed it occurring randomly (but often) with Marvin key chain model and then also with the Jungle boat. Boat takes ~3h to print with my current settings so not a fun thing to try to reproduce. Marvin is quicker to try. My S3D profile is attached for detailed settings.

Expected behavior: Finish printing.

Actual behavior: Extruder motor stops and stays torque off for the rest of the print

Additional Information

I'm having an issue with the extruder motor stopping near the end of the print when there are fine details. This seems to only happen near the end of the print, not in the middle even with models with a lot of fine details (like the jungle boat).

I noticed this first with the small Marvin key chain, as sometimes the chain loop wasn't printing. Sometimes it was. I thought it was temperature issue. Then I tried printing this Jungle boat and noticed extruder stopping near the end when printing the chimney. Tried to print it again and it stopped pretty much exactly at the same spot (measured with caliber). If I print this chimney alone, (by dropping the model height in S3D), it prints fine, so nothing in the model as such.

Setup:

This is not:

P.S. never mind the stringing and otherwise bad quality. Experimenting with this new hotend (and not succeeding) img_20210320_171924

I had the same problem with chitu (xy2pro) fw on x axis. I tried to rise motor currents, additional cooling for motherboard, a lot of spent time to tries. I bought another motherboard, no success, and then I bought a new motor. The problem remains, in fact more rarely, but not good at all. I've got some fw trial from Tronxy's customer service, but no success.Then I began use Marlin. (Better but fails again at fast accelerations) The final solution for me was: limit all speeds to 150mm/s, acceleration to 1500mm/s2 (x/y), after that I never seen motor stop again. It is a half-solution, but no more hope remained to find better. This is not the only annoying issue with this coffe-grinder, so I'm happy with this limitations... In fact, extruder was good for me

Also after failing and after the print has finished or the job has been cancelled, the extruder motor does work when trying to manually extrude from e.g. octoprint.

Thanks @Pedro8005x for commenting and sharing.

Sorry for being a bit spammy but I opened an issue at the main marlin repo too as I wasn't sure if this one is a too active. I went to really try to reproduce this and didn't take long to find a good model. The basic string test. That I managed to print once fully, but then 3 following tries made extruder stop exactly at the same layer. This made me doubt it would be hw issue and as I noticed this screeching sound (usually) before the failure I doubt it's the slicer either.

Here's more about the new finding: https://github.com/MarlinFirmware/Marlin/issues/21390

@Pedro8005x, it could be that this indeed is either TMC driver issue or something as I too experienced stop with one of the XY motors too. I want to utilize full speed of this large scale printer so limiting speeds is really not ideal. It's not really a problem if I print 0.6x0.5 layers as even a Mosquito clone starts to bottleneck with those thicknesses and 100mm/s is enough there, but with thinner layers it just has to fly or everything gets painfully slow. For a hammer solution I ordered a Duet 2 Wifi clone for 60 bucks.

Closing this issue as a duplicate to the linked Marlin ticket. Hopefully @rhapsodyv or someone can give a better closure to this at some point in case it's a generic issue with these TMC2225 drivers or something.
