Hello, yesterday I’ve unboxed and assembled my new A250 for 3D printing. Nice parts, well packed, organized and good looking.
Successful initialization, BUT! When i try to start bed calibration, the head goes up, calibrates for the end point, then to the left, then down. Y-move but shortly. (probably not smooth enough?).The head comes down and runs down to the bed, then it stays there or moves fortuitously with motors “ON” (humming). On one try X-movement made a bad scratch into the building plate with the print nozzle.
As I haven’t found any procedure to skip the bed calibration I cannot even try the new firmware.
New try: In “origin set” mode, z- and x-axis correctly search for a reference position, y-axis motors just move a bit or run to the rear end position without smooth end stop - humming
Cables are correctly connected.I also interchanged the distribution boxes - no effect.
M520 and M500 commands also didn’t change the situation significantly.
I have fed a similar topic into the Snapmaker 2 forum before, but it didn’t become visible
