Hot stepper motors, how much is normal?

Recommended Posts

they can get toasty warm thats true. After maybe 20 minutes printing. they can get pritty hot.

You can of course go down to the electronics board and with a small screw driver turn the POTS to the left a tiny bit and that will reduce the power going to the motors.. ie cooler...

But id be a little slow doing that. Normally the POTS are set to a default by ultimaker for best overall performance..

But if you feel secure enough.. have a look and turn the POTS back a little.. just be careful with your electronics board !

M907 X1300 Y1300 Z1300 E1250

should set them all to default currents. Values are in milliamps and 2000 is the max although I'm suspicious of some kind of bug as someone reported that the extruder gets more powerful up to around 1500 and then starts to get weaker again as you go above 1500 - I think this might be a hardware bug with the stepper drivers. I'm really not sure.

Also B is for the second extruder M907 B1250

I played with this and reported results here (see posts #1 for the photo and #19 for the current testing):

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
