Hi, I installed my Hemera on a 24v Hypercube Evolution (I did order the 24v version) Printing starts perfect, but after a while the stepper/heatbreak gets so hot that the filament melts and grinding occurs, until it stops extruding at all. Filament settings: PETG, 240 hotend 80 bed. At first I thought it was retractions, so I disable them but that did not help. Esteps and other settings have been put into the Reprap firmware. Running as low as 650mA for the stepper still gets the Hemera scorching hot (unable to touch). Heatbreak fan is running fine. Help?
