I found a video on youtube using servos but that is maybe a bit to much.
0,01mm sounds a bit rough but just might have to see and test it. I mean in the worst case I will have to replace the drivers.
An advantage of the Eding system is that you have a macro and you can start programming and calling your programms. So if your atc procedure is a bit complex you can programm it all in your macro.
Would you have an idea how to drive your atc by g code? Should be possible with the macro?
Ok, so it won´t take me years to do all the wiring that is good news.
