D-bot wobble !! :-( (19 replies)

Hi everybody,

I have a impossible wobble!!
My mechanic seems good but still have wobble.
With a comparator mounted on the carriage I can see the default but can't find it.
My config:
MKS Sbase 1.3 16 micro steps, 20 teeth pulley on the motor, 60 teeth on the leadscrews, 1.5mm pitch leadscrews, gt2 belt.

The motor current is ok,
I tried different motors,
I tried 2 motors at same time with current at 2.2A
I tried different pulley config,
I tried different position for the belt
(I ordered bigger belt: 10mm gt2 if the belt stretch too much)
I tried full steps, 32 micro steps 16 micro steps, 1/2 steps.
I changed Z wheels guide to linear rails (really stronger setup :-) )

Nothing fixed the issue

If you have an idea :-) to help me

Thanks
