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.

Thanks
Vinny
