What a great package! I previously ran my CNC with a Gecko 540 and Meanwell power supply. There was a constant audible hum and motor chirping at start and stop of movement. Now, I can't even tell if it's on when idle, and the motors run smooth and strong. Install of .xml and ethernet smooth stepper plug in was well documented and easy, and after a few changes to the motor tuning and ports and pins in Mach3 I was up and running flawlessly. A couple things to note: the slaved axis comes up as "B" and not "A" as it did in my previous system, and the active low setting for the Z axis needed to be switched for the page up and down keys to correspond with direction of travel.
I can't wait to wire up the proximity switches and z touch off plate.
Thanks for a great product.
