Seems you are the lady in the know around here. Just tried to upload a video but failed due to being new.
My Snapmaker arrived yesterday, set up was pretty simple and strait forward until I went to calibrate the 3D printing module. Initially the all X, Y and Z axis appeared to be working, upon calibrating the Z axis would not go down enough to reach the print bed. Exiting the calibration via either saving or going back reset the homing point, however the homing point was roughly 10mm higher than it was previously. And every time it finds the homing point it is another 10mm higher.
Back in jog mode again, the Z axis will only go up, not down. It will go up past its means to, and start clicking a rather nasty click. Its interesting though because for every 10mm I push it past the Z+ it will then go down 10mm.
I updated the firmware to 2.6, and the problem persisted. Then 2.7 and it had Z- and Z+ movement again, until starting the calibration process, then the same problem.
I have tried switching the ports between 4 and 5, swapping the linear modules, power cycling with the Z axis in its min and max positions. Still no joy.
Do you have any ideas?
Thanks for your help. I have read though a lot of your posts and they have been most informative.
Oh and if it helps narrow it down, it’s the model with the smaller screen.
