No tax free between Sweden and Germany. We voted against tax free when we voted for EU membership... so it was gone in 1995 when we joined the EU. :P

Anyway, if I were you I'd try with only three motors... and even that is too much for your PSU, unless you have one for every motor. 10A is way too small for 4 x 4A, which requires 16A + a margin if you are using switching supply. 2 motors are OK, but three is already too much, four... I would not even dream about.

Still cheaper!! ;)

I looked at my amp-meter and while doing the test I use roughly 0.8 Amps, in total. So for 5V, 12V, 15V and 48V PSU. That might become an issue later, but as of now, that should not be a problem while testing.

I don't know what I've done, but the programs are now running fine. All of them. I installed the Spindle PWM, put activated the charge pump in UCCNC and put the motors on the floor directly.
Why and what fixed it, I don't know.. What I don't know is if it loses steps. Which I need to see later when I have assembled the mechanical parts and done some testing. Thanks for all the help

As I said at CNC Zone, I think you were having resonance issues from the motors just lying on the table.

I am happy that it seems to work now. Don't worry about missing steps now. I think that is an often mentioned but rare problem. Concentrate on the design of the mechanical parts because I think that is a greater challenge, at least it was for me.
