New to J1, and new to 3d printing. Not new to tech…

Got Luban beta working. Printing happens about 25.4mm above table… air printing. Can’t seem to find a Z axis offset entry anywhere.

Suggestions?

Weird … that’s exactly 1 inch.

I would redo the calibrations, especially if you updated firmware or something like that

I saw that after I updated the firmware and forgot to redo the calibrations. That is exactly the correct fix.

thanks… the Z axis calibration value was set to 30… however, in the adjustment sequence i managed to crash the nozzle into the side of the table. I think it jumped one tooth in X and i see it when using both extruders. The Xy calibration routine fails a the first point of the left extruder.

Will a factory reset allow a recalibration or should i try to move the belt one tooth/

Thanks…

just ran xy calibration again, this time successfully. looks like all is back to nominal operation.

in between, i got cura running with snapmaker support’s help.
