I have a dual Z & dual end stop(micro switch) printer.
Now the Z home position is determined by the end stop.
The Z-home is located slightly below the surface of the build plate.
It is about 0.5 mm.
I installed BLTouch this time.
ABL (Bilinear) seems to be working properly.
The height of the trigger-point and the tip of the nozzle are different by 0.8mm.
I'm using Marlin 2.0.7.2.
NOZZLE_TO_PROBE_OFFSET {X, Y, Z}
Z is compiling with 0.
What is the recommended G-CODE operation at the start of printing?
I think there are two ways.
Please tell me if there is a better way
Please let me know if the command order and usage are different
Plan A
Preparation (execute only once)
G28
G29
M851 Z-0.8
M500
Power OFF / ON
PRINT G-CODE (execute every time printing)
G28
M206 Z-0.5
M420 S1
print-code
Plan B
Preparation (execute only once)
M851 Z-0.8
M500
PowerOFF/ON
PRINT G-CODE (execute every time printing)
G28
