I recently upgraded my old Ultimaker Original with a heated bed kit.
Everything works, but heating / controlling the bed causes random resets. When the bed temperature is set to 0, everything prints fine.
Just setting the bed at 60° and not printing will not cause resets, but when the bed is controlled during a print, it resets frequently, but randomly. Could be 5 minutes, could be 30 minutes.
I suspect switching the bed on/off causes some power fluctuations . Currently don't have a scope to verify this this.
Checked all the wiring to make sure it's not a short or loose wire somewhere.
Anybody seen this before? Any ideas how it could be resolved? Like putting a big capacitor across the heated bed connector, for example.
