3D printing Zero position not real zero

uArm Serial No.: (the No. at the bottom of each uArm reading “UARM-05051706A5”)

Firmware Version:

Operation System: Win 10

uArm Controlling Method: uArm Studio 1.1.13-p1 / Cura 2.4.0

If I want to print 3D I have to set the zero-point before starting. This I can make and after the start goes the arm further down and lifts the complete uArm 3 mm in the height. If I set the zero point higher, he does it anyway.
Where do I have the thought error?
I could of course equal by lifting the robot balance, but that can not be the sense!

Hi @oe1cpw

I guess you’re using CuraForuArm-1.0.3.

We’ve fixed the problem and will publish a new CuraForuArm on our website today.
Sorry for the trouble.

Thank You very much - no problem - wait for update

CuraForuArm-1.0.4 is already downloadable on our website.

Please try. Let me know if there’re further problems.

YES it works fine now.
The only problem is the general Z-Level from the uArm. This differs up to 4 mm. My workaround is to lift the uArm on one side a little.
regards Christian
