Yep, and what a scary moment! In reading all the horror stories of people blowing their gecko's, I was sure something was going to go wrong. But it didn't, all is well. I still need to do some tweaking of the Linux EMC controller software, but I can see the shear power of the servo setup. Actually the steel table that the machine sits on will need to be beefed up a bit before I can increase the accelleration on the servos, as it tends to rock a bit! Thanks for the circuits Balsaman, the err/res is great
