MaxII setup. Which switch on the personality board turns off the speed controller so it becomes manual. Something has gone wrong and it the spindle goes to 500 rpm no matter what is programmed. I tried another personality board so that leaves the sensor on the spindle, wiring, or maybe dual axis board. I can manually increase it after it reaches the low rpm but it is getting to be a pain. I run mostly at 3000 rpm anyway so I just want to set it to manual. The board has two switch blocks. I have been told there is a board with 3.
