[Side fans and extrusion stopped working]

half way through the test they just started working again, I don't know why, but it's all working now, thanks!

Yes! that seemed to do it, it's printing fine now, thanks loads! however the side fans still aren't working, have any idea why those aren't moving?

edit - just started halfway through a test print, no idea why

[Side fans and extrusion stopped working]

Yes, it was!

the feeder was chewing into the filament, I removed the material, cut off the chewed part and re-entered it however once the filament reached the print head, the knurled wheel kept slipping/jumping back and started to chew on the new filament.

As I only noticed the fans weren't working when it stopped extruding so I imagine they'll be different issues, so how would I stop the wheel slipping?

thanks

It's still not working, I've tried it with other gcode files that used to work and they don't, the print head still moves around and the back fan goes, but it doesn't extrude and the side fans don't work, I have no idea where to even start fixing it.

edit: restarting does nothing either

I'm using the UM2, the printer stopped extruding entirely, it isn't blocked, and at the same time or close to it both side fans stopped working. Does anyone have any ideas on how to fix this or even how the two issues may be related? thanks!
