How do you get the numbers for the M92? Can I just use yours or do I have to do it myself? Also, is the Z in line 14 my Z-offset?

hey @Ajax157 you can print a cube, like a 50mm cube, and then measure it. Use the M92 numbers to make it the correct size. You can start without values there and see if it's correct.

And you're correct, line 14 is the z-offset. Just plug and chug to find a good enough number :) I'm not sure where the P6 comes from, it's been six years since I thought about this.

Okay, thank you

Do you know why the z offset doesn't change when I change it?
