Revert recent Neptune 3 Pro printer.cfg changes #34

Closed dj-sf closed 10 months ago

dj-sf commented 10 months ago

Recent changes to Neptune 3 Pro printer.cfg, specifically the one raising the [stepper_z] position_min from -2 to 0, made it impossible for the nozzle to go low enough to perform the paper test, effectively breaking the PROBE_CALIBRATE process. I reverted the values in my printer.cfg to the original values and the problems went away.

This PR changes the Neptune 3 Pro printer.cfg file back to its original values prior to the changes a few days ago in #30 .

Unless there were complaints about the previous values, you may want to consider reverting the other changes made in that PR as well and request verification that the new proposed values do not create any issues.

The Z-axis minimum position was correctly set to 0. For safety, the Z min position should always be 0, except maybe when adjusting the z-offset, but even then you can adjust the z-offset without making the min position negative. If the Z-offset value is less than the probe offset from the nozzle, then there wouldn't be any issues. If the z-offset is larger, then you could adjust the Z-offset in 2-3 passes. Temporarily setting the min Z position slightly negative can be a little faster, but it should be set back to 0 after setting the Z-offset to ensure the printer doesn't try to push the nozzle through the bed.
