Its been about 2 years since I converted my g0704 to cnc and its been a good little mill to learn the basics of cnc but its smallish size has kept me looking for a larger cnc mill. I had been looking the the tormach 1100, and the charter oaks mill when I ran across the PM 940. Looking at the PDF the mill seemed quite stout and very reasonable on price so I went ahead and pushed the button. The mill arrived yesterday and three of us wrestled it into the garage and up onto its stand. There is no picture or video on the net that can accurately portray just how large this mill is. you just have to see it in person. I'm waiting on a few more pieces but have nema 34 1200 oz stepper for all 3 axis, 70v 20 amp power supply, break out board, and the bearings. Just waiting on the 2005 double nut ball screws to come in. The build will be done in stages. First I will get the axis up and running so I can put the mill to work, then later on in the year switch over to belt drive with a vfd to get things sped up. Further down the road i may build a tool changer, but i need to research that one some more. If you are looking to convert a large mill take a good look at the pm 940, I am very happy with what I see so far. One thing i would suggest though is to order the deluxe model with hardened ways. If you order the stripped down version (like I did) it will not come with the electrical box on the back, control box with e stop button, or any limit switches and by the time you tally them into your build you will not save any money by omitting them. Well thats it for now. I have to do some rearranging in the garage, get the goo off the mill, and then im going to start tearing it down. More to come, although it may be quite slow. Hmmm, cant get pics to upload???
