Solved Home offset in RRF?
-
I have a 6HC and I'm almost done configuring this custom printer. I have a 330x330mm build plate and the print head is not center on the bed when I go to X=115 Y=115. I have a lot of experience with Marlin and I would adjust the HOME OFFSET to fix this issue (M206). I can't find a similar command in RRF. The closest thing I found was a tool offset but I don't believe that is going to achieve what I'm after. Can someone point me in the right direction with this one?
Here is my config.g file

@impalanator said in Home offset in RRF?:
I have a 330x330mm build plate and the print head is not center on the bed when I go to X=115 Y=115
115 is not half of 330
So the printhead won't be at the center.... -

@o_lampe Thanks, that was a typo, but the question still remains, how do you change the home offset to compensate for the print head being offset?

@droftarts Thanks, this is exactly what I was looking for.
