Z-Axis moving too far

[Breslin]

I had been trying for the past year to get this working. The update was ok but adding Gcode: "M92 Z400" command and the Gcode: "M500" to save all worked perfectly.

Great advice, would you know what M92 should be posted if it doesn't have the T8 lead screws? Cheers

This fixed my problems!
I had actually used M206 to set the Z-axis offset but then my models were printing about 800% too tall.
Here is the M206 documantation:

If you used that, then you'll need to set the offset to zero when you fix the steps/mm issue with M92.

Now I can do all the other stuff needed to get my prints to come out correctly.

After further tinkering and testing, I found that I actually needed the steps/mm and z-axis offset to get things working properly.

So if you find that neither correction fixes the issue, you may need to do both.
