What is the problem?
I have Prusa i3 MK3S, configured printer profile in octoprint 250x210x210 and select custom bounding box set for Y cord: -4 to 210. Because PrusaSlicer add Y -3 to clean nozzle. WhenI start printing using octoprint, line for cleaning nozzle print on Y: 0 cord.
What did you already try to solve it?
I thing no need for logs because all logs are ok. Only question is how to activate negative move in Y. I made gcode in prusa slicer app. If logs are necessary I will add it.
