@sastas said in Auto Bed compensation torque problems.:

The compensation move is(for me at least), when the 4 leadscrews align the bed. It do the 4 probe point, then it goes down, then it does the compensations, then it goes to the point I configured.

I'm sorry for the delay in responding. What makes you so sure that the motors are losing steps?

A bed with 4 independent Z motors is over-constrained. Perhaps the problem is that the bed is slightly warped, and isn't sufficiently flexible for the motors to overcome the warp?

Yes, 1.19.3 DWC is recommended (it works with 1.19.2 RRF as well).

Thanks, I've updated the wiki to mention that you need firmware 1.19.

It's not really practical to use 5 supplies and would be very tricky, there aren't separate power connectors for each motor driver which are all on the same bus on the board so you'd end up connecting your supplies in parallel which I'm fairly sure would be a bad idea.

If you were using external drivers you could run a supply to each one for x y z and e but then running the rest of the board on 2.5A, even if the bed were powered separately, including your hotend heater would be impossible.

Sounds easier to stick the 5 supplies on ebay and buy a 10A one and possibly pocket the difference.
