Re: sherline motor/speed control wiring IT WORKS!

Hey guys, more news! I got an LED to turn on and off using M03 and
M05 command on CNCPro! Connect a wire on pin 1 (+) and then I used
ground off of the camtronics board (this should work for others too).
Check the voltage output and see if it goes up and to basically 0 by
pressing F5 (this turns on this I/O). On mine is a little under 5
volts. Connect your device between the two wires and it will turn on
and off on command! Works so far! Tomorrow I will get a solid state
relay and hook it up to the I1 and I2 on the sherline speed
control....Well let you guys know if it works tomorrow!!! Can't wait!
