Extruder randomly starts spinning backwards
-
Hello,
After some time of printing with my RatRig, I have faced an issue I have never seen before. Everything is doing great, but sometimes extruder spins backwards for a couple of seconds (I do have a video, but it's too big to upload here).Exact same problem happened on both of my printers and in the exact same spot (both printers are identical). At first I was thinking maybe the file is broken or something else, so I just rotated the model and this problem disappeared I have made a couple successful prints. Yet, I have started to print another model and the problem came back and I can not solve it. Changing the model orientation does not help anymore and now I suspect that it has something to do with the printer itself, not the slicing soft or the model.

@Arminas which board and firmware version are you using, and which slicer did you use to generate that file?

@dc42 While creating a discussion here, I have been trying to think what have I changed/upgraded lately and I have one most recent upgrade in mind - input shaper. I don't know if it's a coincidence or not, but I have disabled the M593 command and so far the print looks good. Can this be the case?

@Arminas as i said, its a known issue in 3.5b3 in general due to the input shaper changes made

@jay_s_uk now that makes more sense, thank you!
-
@jay_s_uk One more question - now it shows "Incompatible software versions
The installed software versions do not match. Please operate your setup only at equal versions to avoid potential incompatibilities and unexpected errors." after I upgraded to 3.5.0-b4. Anything else I need to upgrade? -
@Arminas all boards need updating (so toolboards etc if you have any) and DWC also needs updating
-
@jay_s_uk case closed, thanks again
