No Probs if you need hand getting it in let me know.

Hello I just got My Harrison M300 CNC into my workshop and I have exposed all the servo motors ,encoders and drives Do any of you out there know if I can run it with Mach3via some sort of BOB .
I have a list if part numbers 1 Z axis motor is a SEM Permenant magnet DC motor Type 30E4-30 with constant stall torque of 2.1nm 80 volts pulse amps 22 Xaxis is also sem type 30H4 constant stall torque 1.1 nm 120 volts . Both z and x drives are Anilam model GA4561-7L . THE X encoder is an anilam L25G-250-ABZ-7406B AND THE Z ENCODER IS ANILAM L25G-200-ABZ-7406R-SPTO2-S. If all this makes any sort off sense at all please help . Initially I need to know can the mach3 thing be achieved then I can figure out with help how.I have now got 3 small lathes running of mach3 using steppers but this is new to me . Thanks

Got 2 New servo motors an one drive on today Z axis a tight fit but it clears by about 6 mm

In the next weeks, I'll experimenting a bit with several Leadshine DCS810
DC-Drives. They can have 80V at 10Amps continous and 20Amps peak for 1 sek or so. If you don't have any manuals, then this parts can be good for your machine, although the Z-drive should be a little bit more capable
They write for motors up to 400W, but your 2,1Nm motor must have (at3000rpm) 660W.

Hello long time no see. Been busy . This is the story so far . My Harrison lathe now has 2 new servo motors and drives fitted. Not wired to smoothstepper yet but they do jog on the buttons nice. Got smoothstepper and 2 breakout boards fitted and wired to index disk and all the limits .Just got 1 problem . All the m3 m4 and m5 commands work fine but speed commands are totally ignored and it spins as fast as the invertor will let it go . Got lots of gears but I would like to vary it a little. The volts on the bob's stay at 10 (both bob's) all the time 0 to 10000000 rpm its all the same . Any ideas its driving me nuts.

Hi Keith,

I assume you are using a good quality multimeter to measure the 10V voltage. My Maplin specials do not average enough to give a good measurement. They always give a peak measurement.

Have you gone through the spindle calibration so that Mach3 can write the linearity data?

have a look at this one too:
