Ok so here is the deal, I have a Anet A8 and it probes the bed is 9 points.. it's fine nozzle does not crash into the bed and whatever.. however the start of the print where I have it print a 4mm line before starting the print for whatever reason the nozzle goes below the bed level when trying to make that 4mm line now (changed the nozzle for TPU printing) Maybe I don't have the M851 command right.. but this is how I did it..
G28
G1 X110 Y110
M851 Z0
I did do the M500 command to make sure it was saved and all
I lowered the nozzle to the thickness of the paper.. Now sometimes what would happen is either my Z height would be 0 Or it would not be (-) but something like Z10.45 I haven't been able to print for a few days but I would like to figure this out because it's just having me puzzled.
Another question doing a G28 then doing a M851 Z0 and then M114 should the Z level height be Z0.00?
