…Inconsitent extruding
The extruder is acting very wierd. I have no idea what to change. I have changed my mcu to Skr 1.4
everything works but my rotation distance is changing between 7.711 and then double efter reboot.
I have to change all the time. First it prints perfekt at 7.7 and sudenlly it’s 15.0 and total overextrusion at 7.7. I have a BMG extruder. Please help me it’s very frustrating.

Hello @olovfr !

Have you checked the stepper motor current?

Hello!
I think I have sorted it out it was my bl touch that was the problem. It gave me different heights every time. Now it seems to be working. Thank you for answering.
