> Hi, I’ve just cut my first piece on my just assembled MetalMaslow. It’s cutting great and surprisingly accurate. The only trouble I had was getting the pitch of the Z-axis correct. I set the Z-axis pitch at 8, as suggested in the forum. However when I moved it 0.5mm down it actually moved 6.4mm. A factor of 12 times more! So after some calculations I ended up with a pitch of 99! I changed the Z axis pitch setting in GC to 99 and got the correct displacement. Of course I can live with this setti…

I think what might be going on is that @metalmaslow is telling people what value to use for pitch to make the system work using the stock motor encoder’s setting. All that matters is pitch\*encoder counts (edit: might be encoder counts / pitch) to come out to the correct number. Try 99 and see if it works.
