Earthing?

[Edward]

One problem I experienced with one of my motion controlled cranes was that the drivers - 6 of them - were placed too close together in the box (which was open top) and didn't have enough space to "breathe" and there was no fan. To start with, it would all function well, but after some minutes some of the drivers would start to have a life of their own:)

I put it down to the heat, the drivers didn't have the cooling base either. With a 3 axis machine, it is easier to give them space for ventilation plus I will use a small fan as well. I also had some minor earthing problems with another machine, so the lesson learned is to anticipate all this and be on the safe size to avoid later problems.

The Kflop communicates via USB, and I haven't had any problems in that respect, been using it almost daily for three years in my work as a photographer and for motion control you can't afford to lose steps or have a bit of backlash, it's servo motors and harmonic drives for every axis. I use a good quality shielded cable, with ferrite chokes at both ends just as a precaution.
