Well, I put a millpwr on my bridgeport. What problems are you running into?
there's a few forums out there discussing the HF / Grizzly etc line of mini-mills and upgrades. I would look at https://littlemachineshop.com/ for info in their discussion forums as a start.Quote:

Yea I was hoping to find someone local with experience doing a conversion I have been going at this for a few months now and can't figure it out
I haven't converted a HF mini mill, but I've built a couple CNC machines (router and plasma table).
When you say Z is binding, does it bind with the manual handle on it, or just with the stepper?
For wiring, and programming, what are you using for a controller and steppers?
How are you generating your G-Code? Drawing in Inkscape or Fusion 360? Are you using a kit from someone and if so, do you mind sharing who? On my Cheap Chinese Mill I just went with digital machine scales on all 3 axes and ended up with a 'poor man's DRO' that works great. I also built a Shapeoko CNC router and beefed it up a little. I recently finished a 20-week course in CNC Operations at a local Tech College to prep for a new career path, so I know just enough to be a little dangerous ( 'I don't have a License To Kill, but I do have a Learner's Permit'). I've been a garage/hobby machinist for about 20 years.
