Hi, my name is michael and i am from Germany, so please excuse my english.
After 7-10 succesfull prints the cleaning precedure on my Mini failed today. the printer homed correctly, heated up and the printhead came down on the left side of the cleaning pad, as usual. but then:
instead of “swiping” shortly over the whole pad from left to right, the nozzle touched the pad simply scratched to the right until the nozzle crashed in the padholder on the right side. i immediately stoped the print, which took 2-3 seconds until the command was send to the printer. in this time the X-axis was blocked and the belt jumped on the steppermotor.
is this a common problem? how can i prevent it from happening again? the next print i startet was successful so the startup gcode seems fine. i did not modify the startcode in any way.
happy to hear ideas from you all.
