Hi,

My duet wifi will only calibrate up to 0.108 accuracy and if I then look at M665 values, arm length is way off showing 223 whereas the actual length is 215.

I have a kossel mini with linear guides and ir sensor in the effector.

Also my mesh leveling is erratic at best, but is very accurate if I run the mesh leveling with same settings twice.

I really have no idea what I'm doing wrong anymore.. Delta's geometric values are within tolerances. Anyone familiar with these weird results and able to help?

i think i solved it...

any black surface makes the ir sensor useless. i purchased white buildtak and all my problems are gone.

i tried:

black spraypaint
easy peelzy
black buildtak
black pei
all the above with glass

nothing worked

regards and thanks
