G30 start Gcode
I have problem to keep righr nozzel distance from bed.
After power up printer it homes all axes and perform bed compensation
G28 ;Z max, X & Y min G0 X150 Y150 G30 ;find real Z0 G29 S0
When I start printing now without starting script it prints perfectly, but if I use G30 (starting script) it starts printing 0,8mm above bed.
do you know why? thank you
We need to see the config.g, homeall.g bed.g files as well as a description of what kind of printer it is, and which duet board it is, and what firmware version you are using.

Yesterday I thing I found the problem. I set Home Z max to 250mm but actualy it was 250.8mm, so when I started G30 bed raised to 250 and BLTouch somehow automaticaly click itself even if the bed was still 0.8 below triggering. ???? I don't know. ( I tried disconnect Z stepper an run G30, after the printer was thinking it raised bed 250mm BLTouch clicked and printer was displaing Z = 0.0)
Now I defined Z Max 260 and it seems working fine.
Board is Duet2 Wifi with firmware 2.04RC3.
you config does not have any settings for the bltouch.
sorry, I forgot. Printer works with multiple tools so config is just generic definition of machine.
For 3D printing I am using macro Hv6BS60.g .
you are missing
M574 Z1 S2
you can not use z max endstop and probe at the same time.
