Octopie is connectected via cable and USB to my Ender3v2. I am new to all this and made a fresh setup today on a Raspberry Pi4. At first Octopi told me that the firmware of the Ender was outdated, so I also updated that. I set all the parameters in Octopi. Bed size, nozzle heat and so on. I can connect via Webinterface to the Pi and I can move axis and see all through camera. I load a file and press print. The printer heats up, first bed then nozzle. As soon as parameters reached the nozzle moves to left side and hits the stopper but the stepper engine does not stop and tries more often to move to left and then the printer kills connection.
Without octoprint the printer prints everything as the last 2 weeks as normal - no problems at all.
What did you already try to solve it?
Have you tried running in safe mode?
Did running in safe mode solve the problem?
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
