I am an entry level CNC enthusiast with a Journeyman electrical and light electronics background. I am currently building a C-Beam machine and am using the CNC USB controller Mk3/4 (4 axis) that I had bought for another, larger, build. So, I need to buy another board. And I was interested in the CNC xPRO V4 Controller Stepper Driver. From what I gather, it is not necessary to use stepper drivers in addition to the board because, they are already built in. A friend of mine, who has much more CNC experience than I, told me that this board would short out with the high torque stepper motors. Which, is what I Currently have and would prefer to use on the next build as well. Can you tell me if that is an accurate assessment or not? Or how this board compares overall to the MK3\4 board? Also, I like the plug and play ability of the xPro V4. And would like the ability to add a laser, Z-probe and a rotary attachment down the road. Any input would be appreciated.
