J1 with Luban prints way over table

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.

Nice! Post some pics of some plastic!

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.
