Hello I got 2 motors you saw in the video on my Harrison m300 and they work fine . Its a bit tight under the cross slide and you have to grind a little of the lead screw carrier but not a lot. They wire up and set up really easy and work just like that . Pulse maths are a little difficult because of the the gearing . I resorted to a readout temporarily fitted to fine tune the numbers. and it works . If you use these motors I will let you have the pulse setting's.
