I think you need to check the stepper mm of the printer on LCD.
Check the rod type and use the M92 adjust it to 400 or 2560.
Then test it again.

Yes! Thank You!

I had originally used M206 to set a persistent offset which got me where i needed to start but the models were printing about 8X normal height.
So if you have an offset issue then the solution is M206 Z[offset value] then M500 to save it.

Otherwise if its a stepper issue the M92 Z400 then M500 to save it.

It's a little hard to find useful topics when the titles aren't particularly clear or descriptive.

I stumbled across this topic for the steps/mm issue. This seems to fix my problems.

To check if its a step/mm issue send a manual command to move the Z-axis by 10mm and observe the actual distance it moves. If it's roughly 8 times greater (80mm instead of 10mm) then you need to change the steps/mm from 2560 to 400.

If it's an offset issue then this page should help:

Hope this helps
