missing steps?

The power supply is 24v 14.6 amp, which is the max voltage that the TB6560 board can handle.

At the moment, I am only moving (working with) one axis at a time, but come to think about it, th effect may be more pronounce when all three axis are moving at the same time...

hmmm... If you really think that this is power supply related, I think I may just sell these electronics and try my luck with a smaller desktop machine since I'm going to have to spend more money on additional electronics anyway.

Not sure if this is what your describing about your Z-Axis falling down is, but it could be the Z axis is back driving.

I would consider that except that it is occurring on all three axis.
