Thanks, it is a hardware / driver fault. I switched the 4th (A) axis with the X, since i barely use the A Axis - problem solved.
Just waiting to get a new exchange.
But while i am on this and the Drivers are REALLY QUIT GARBAGE :
Do you know DECENT drivers which can be used in exchange for the TX14207? Do i really need to go for Leadshine? - on the other hand 59Bucks for a Driver shouldnt be the problem - if thats the price
