I recently finished my printer but I still have some issues with the z-axis. All my prints are out of shape on the z-axis. I'm using a Dell M115 HD, Ramps 1.4, Pololu stepper driver, Nema 23 stepper motor (http://en.nanotec.com/fileadmin/files/D ... 1008-A.pdf), 16mm Rod (4mm pitch per rotation) and 1/16 micro stepping with configured 800 steps per unit with the modified mUVe firmware. Does anyone have a clue for me?
Layer height: 0.1mm
First layer time: 20 sec.
Layer time: 15 sec. (the projector has just 450 Lumen)
There is no wobbling on z. There seem to be no problem if I move z manually.

What do you think?
Thank you so much!
And please just ignore the cracks on the base plate.
