So…I have the machine assembled with all axis moving freely. I am an old school Mach3 guy. In doing some preliminary testing this evening with my steppers I have a lot of heat on the motors. For my other CNC builds that use wood or aluminum the stepper heat wasn’t a concern. And for those machines having hot motors was pretty typical. For PLA mounts the heat bothers me. I put a thermometer on the motors and after about 10 minutes the temp was around 110F.
I would imagine that the Ramps set up runs much cooler, but having never played with that arrangement I don’t know.
So how hot are the steppers on other people’s builds?
