Hey everybody. I'm just getting started and I am new to this machine, HF mini mill x2. I have been reading about using the KBLC board to upgrade the power to the motor. I bought the parts online as were recommended in several site and hooked up the wires correctly as best I can tell. I am not sure if something is wrong or just not adjusted right but the spindle sort of pulsate on and off about a second each way. Turning the potentiometer (5k) doesn't seem to do anything. also I noticed the light on the board for the ARM blinks with the pulsating. Its kind of hard to explain, just hoping maybe you could point me in the right direction.
