Just built the mrk3s, fantastic build, one of the best kits I have ever built.
I have tried a few prints and have noticed the extruded motor get quite hot. 54deg is what I measure after 1hr.
I’m concerned this is a little hot as I want to put my printer into a cabinet to do ABS printing. The PetG will start failing at 80deg on the motor mount if things get to hot.
is there a way of reducing the current to the extruder motor?
RE: Extruded motor
Have not had any issues printing ABS in an enclosure here ... if you are looking for current reduction options to the E motor, there are some experimental settings in the 3.10 firmware that you may want to play with.
