I got my machine up and running, after I did a calibration I started the spindle, the speed went up and kept going up past 4000 when it got past the middle of the blank area between min and max I got a little nervous and hit the e-stop. I checked everything and it seemed OK so I restarted the machine. Now the speed control only works in that no mans area and is reversed so that when I try to go up the speed goes down and when I try to go down the speed goes up. It only moves about 1/4 turn of the speed indicator and stops. Any ideas on this one?
