In that event, the OP should be downloading our install cd right now. Anything else is just escorting him down the garden path to an expensive captivity. Lurking here, and seeing the excitement over Roberts new TP, I see LinuxCNC as about to take a giant step forward in the industrial arena where spindle power and rpms, plus coolant are far more likely to exist than in my backyard shop, already exists and can be taken advantage of to increase production. Sure, I can jack up the voltages and make my mill move faster, but at a max revs of 2500, and a 200 watt motor that realistically makes it to about 1 amp on the meter, aka 100 watts and is in danger of hanging at that single amp, I simply can't cut fast enough to take advantage of this when a hang is an instant broken $15 tool. But that is my problem, and NOT LinuxCNC's. I am looking rather hungrily at the spate of 400 watt spindle motors that have shown up on fleabay for askings in the 70-90 range, as potential replacements for that whole outsized & empty contraption called a 2 speed head on my toy mill. Having drilled & tapped that casting for other very handy accessory tools. the ideal situation would be to expand the quill bore from 49mm, its present size, to 52mm which will fit the new motor as the ideal conversion path. But realistically I can't do that boring job, so the alternative is to just saw that quill bore off, and pretend there is enough iron behind it to be able to use the mounting kits available for the new motor. Most of which seem to be equipt with an 1/8" max tool diameter R8 or so collet. But 12k+ rpms sure whets my appetite to do just that. I have a 2nd casting on hand already, and can easily make another pair of the ball bearing base gib length enhancers that have finally fixed the stiction in the z axis motions, so that is certainly an option. But changing the casting also involves duplicating the mods that anchor the Z axis drive screw into that casting. That was all done free hand, and would be an easier job to do the swap if I just bought another post and built up another complete Z drive using a 16mm ball screw this time. Same rotating nut idea however. With my lathe now capable of doing that turning and boring for the ball bearing nut holder, I can come up with a working drive in half the time it took 6 years ago to make that one. It was 3 or so hours a day for several months once I had the plan in my head. I also have a MIG welder I didn't have then. Changing out the whole post would mean that there are no parts of the original $400 HF mill left sitting on that steel kitchen base cabinet. The base and table have already been replaced with the bigger ones from LMS. Mmm, I wonder how much the post and sled castings for the X3 cost, says he, to no one in particular. Thats its next flex point where additional iron would be useful. Need another coffee transfusion yet, Christmas gift exchange at the tv station at noonish. Gotta get moving. And damn this knee. A good nights sleep is always just out of reach. Put off getting old as long as you can guys, its not always just a long vacation.
