Trouble with V3 Z offset using old and new firmware
Posted: Sun Nov 27, 2016 10:27 pm
I am having trouble calibrating the bed on my V3. I have tried both the 'old' V3 probing gcode file from SeeMe and the new development firmware. In both cases I am getting a Z0 that is about 0.15 mm above the bed. This measurement is consistent at +/- 100 mm in x/y so the bed is pretty flat. I always clean the nozzle and run the calibration with cold bed and extruder.
I discovered the offset after a lot of frustrating work trying to get ABS to stick to the bed--the nozzle was just to high.
Currently I am using a Z offset of -0.07 mm and it seems to give a decent first layer, but I want to fix this problem in the printer so Z0 is really at 0.00 mm. Here are the EEPROM settings after running the new development firmware:
What is the 'correct' way to adjust so I don't have to worry about it when slicing?
Thanks in advance!
