Hello, I am trying to identify and get more information on the motor and driver board on my Micromark X2. Ultimately I want to add a spindle enable signal from my CNC computer and speed control if possible. For now knowing exactly what I have and what it could be replaced with is enough. I do have an Oscope and logic analyzer should I decide to really take a good poke at it.
One of the things that bothers me is Micromark says that cutting or applying power with the speed knob not at zero will cause the board to burn up. Given that and its other limitations I would like to know what it really is and if it has some hidden features I may like or if it can just be swapped out with another board.
Here are some pics:
The board has the MCU on a daughter card in the upper left with some opto isolators.
