Neptune 4 Max - trying to fix negative z offset
Owner of a N4M for a couple months now - wow. Ive never had this much trouble with a purchase in my entire life. I've been able to get prints, but the process can sometimes take days in between troubleshooting to get usable quality. Coming from a Bambu Lab A1.
I read that having a negative z offset was a sign that I needed to do a z Probe to calibrate the position of Z0 ( where the nozzle meets the plate). So i tried running the PROBE CALIBRATE command, but I couldnt get results to save after Issuing ACCEPT command, also tried running RESTART FIRMWARE afterwards for good measure on a 2nd atttempt... so I decided I probably had compromised my .cfg or settings somewhere, did a factory reset on the machine and switched to the newest ORCA slicer.
Every time Ive run CALIBRATE PROBE, do the TESTZ commands and get a nice calibration in the 0.14 - 0.15 range, it never will save. I tried manually adding the value to the .cfg which seems to have worked, however after doing that I find when issuing a Z0 the position is way too high off the bed. The Z offset is 0.0 ( as Ive never issued a SET GCODE Z OFFSET because I need to sort out why Z0 is so off - Im trying to avoid have a negative z offset like I did before.
I've read other people have this exact issue from over the last year - is there a workaround yet? Am I supposed to avoid using probe calibration as its now a broken feature?
Im willing to do a full factory reset and start over if someone knowledgeable would walk me through.
