CNC RS-CNC32 Z setup

[Ory]

Hi,
I followed all the steps in order to build the CNC... it works very well but I have a problem with the Z-axis setup... when I mill it don't respect the correct depth that I have wrote in the software (Estlcam V11)... could you help me please?... I looked into the firmware but I didn't find any Z setup for the screw steps or other... In the site I saw different ways to resolve the problem but I don't have any of thoose devices and I'm not a programmer...so could u help me with this step by step?
Thank you.

Hi Ory,

Without milling, does the Z axis move coorectly? Regarding to this page, does the axis move to the desired distance ? If not, the lead of your ACME TR8 threaded rod is surely not 2mm. The best solution is to change your ACME TR8 threaded rod for the right one.

See ya,
