Its an axis Rick, and will need the same hardware as driver for whatever motor you have on it. Mine has a stepper motor, and the stanza in the .ini file looks like this: [AXIS_3] TYPE = ANGULAR HOME = 0.0 MAX_VELOCITY = 50.0 MAX_ACCELERATION = 100.0 STEPGEN_MAXACCEL = 200.0 SCALE = 320.0 FERROR = 1 MIN_FERROR = .25 MIN_LIMIT = -100000000 MAX_LIMIT = 100000000 HOME_OFFSET = 0.0 HOME_SEARCH_VEL=0.0 #HOME_SEQUENCE=3 BACKLASH = 0.056 Driving it with a 2M542 driver, hooked as (from the .hal file) setp stepgen.3.position-scale [AXIS_3]SCALE setp stepgen.3.steplen 1 setp stepgen.3.stepspace 0 setp stepgen.3.dirhold 10000 setp stepgen.3.dirsetup 10000 setp stepgen.3.maxaccel [AXIS_3]STEPGEN_MAXACCEL net apos-cmd axis.3.motor-pos-cmd => stepgen.3.position-cmd net apos-fb stepgen.3.position-fb => axis.3.motor-pos-fb net astep <= stepgen.3.step net adir <= stepgen.3.dir net aenable axis.3.amp-enable-out => stepgen.3.enable ... net astep => parport.0.pin-08-out setp parport.0.pin-08-out-reset 1 net adir => parport.0.pin-09-out You'll have to "home" it, even if its not plugged in at the time. Be sure the cable to the motor is never plugged, or unplugged, without first turning off the driver power. Drivers in general do not tolerate that at all well. With a servo motor, I highly recommend jon's (Pico systems) PWM-Servo amplifier, its bulletproof and can handle up to 160 volts dc for the motor supply. I've used it for a spindle motor driver twice now. It can reverse the 1 hp motor of my G0704 from 2700 rpms fwd to 2700 rpms reverse in a small fraction over 1 second elapsed time. G33.1's are done before you can think about it for small taps. Just make sure the chuck holding the tap is tightened to about 1 degree from broken, because if it slips, the tap is history. I've been looking for a tap holder that grabs the square on the butt of the tap, but those things it seems all have a different, unique size.
