Wrong Scale on Z axis after firmware update

[matthiash 0]

Hello,

I updated the Firmware on my ultimaker and now the scale on the z axis is always wrong.

A part which is 36 mm in z direction in cura, is only 22 mm high after printing.

Any ideas what the problem is?

Cheers,

Matthias

Sounds as if the number of steps per mm is wrong in the firmware. I guess, you compiled your own version of Marlin or built it at marlinbuilder.robotfuzz.com? If it's the second, check the number there; it should be 8/3*200=533.33333 (as long as you use the standard z thread and motor). If you have an Ulticontroller, you can check there.

EDIT: You can also use the M92 code in your start.gcode (UM1, correct?)

Found the problem the z axis stepper did not work probably, tightened the screws and it s working again.
