z-offset with two printheads
-
you would adjust the Z offsets using G10 in your config. Best to probably leave the first with a 0 z offset and just the offset from the first head to the second on just the second one

and how do I set the first z-offset?

i have successfully done this step by step... how do i add a second print head in the code?Here my code:

G10 P1 X0 Y0 Z0 ; set tool 1 axis offsets
G10 P1 R0 S0 ; set initial tool 1 active and standby temperatures to 0COk, but if the nozzle is 1 mm higher, then I can't do a test at all, because otherwise it will go into the print bed
-
@axiom can't you move tool 0 out the way of the bed to allow it move higher?
-
@jay_s_uk I can unscrew the nozzle from tool 0
-
@axiom so how do you expect to get to tool 1 if tool 0 is in the way?
-
@jay_s_uk
then I have to change something in the hardware... can you recommend me something? -
