    I have a large knee mill retrofitted with the Centroid 4 axis all-in-one card rather than Acorn. That made me love Centroid controls. The Acorn with Clearpath servos will give me the same capabilities in a smaller machine. A lathe I have has DC servos already mounted and because of clearance issues those motors would be hard to replace. So I'm thinking LinuxCNC for the lathe, but so far I haven't found step by step Linux conversion info (it's probably out there somewhere I haven't found it yet though).

    As far as these retrofits go I'm not interested in learning experiences. I just want "buy this and hook the blue wire to terminal 1" type stuff. I have more money than time so with Clearpath servos's I'll buy all the premade cables, etc rather making my own.

    As I wrote before, I am happy so far with the Acorn and software itself. It is the attitude of Centroid and their representatives that leaves a lot to be desired. I thought Keith was smarter than he demonstrating. Too bad. The first thing they need to do is get their help videos and downloads organized so that a person can find what they need without having to post questions on the forum. It makes no difference to me and I sure as hell am not going to educate them. They couldn't afford me!

    I resent that remark about the unwashed! I take showers at least once a month.

    It's interesting to me that a 3 character search works on the phpBB software used on the Acorn forum but not here using the vBulletin software. I assumed that it didn't work anywhere. I guess I've only tried it on vBulletin.

My machine to be converted is an Emco F1P, with the "P" meaning production. So I searched for "Emco F1P" in quotes assuming that would bring up only topics with that exact sequence of letters between the quotes. At least, that's the way it works on a good many forum searches.

    Instead it brought up every post with the word "Emco" in it. That was a lot of hits, most of which were of no interest to me. Never did find anything on the F1P model.

    The intention of my search was to find what size axis motors the F1P mills use and are they a standard like a NEMA 23.. By Googling I did find a partial answer to my question. A Youtube video showed an F1P converted, no details though. In the follow op to the video there was a question about the motors, they may be NEMA 23 except with 6mm shafts instead of 6.35mm (1/4") which is standard on a NEMA 23.

    If you go DIY, there is an expectation that you aren’t an idiot, can diagnose issues, speak at a technical level, understand at a technical level, and apply properly at a very technical level.
    I’m not calling anyone here an idiot, I actually view this forum as the “brain trust”, where the smart people hang out.

    Marty does a lot of conversions, you should post your question on that forum, either Marty or Keith will chime in, especially if it helps them sell you an Acorn or better.

    Well, 0 to 10V is standard on nearly every VFD that I have messed with or read the manual for. That "should" be about as easy as it is possible to get.... connect it where the pot goes.... just get the (two) wires on the right screws.

    It IS pretty down and dirty stupid to be mad at a completely different company and product over one of those. The only excuse I can think of is if there is a spindle speed control output on the system, which I would have to assume there is, and something about THAT was the real problem.

    I myself will give advice on VFDs, which I happen to know a bit about, but NOT on one of those chinese ones. Too many of the ebay units are ones that seem to have been taken from the "failed test" pile, and sold out the side door of the factory.
    Acorn does put out an analog 0 to 10v or 0 to 5v signal to control speed for a VFD. None the less he should get his VFD to motor working with just the VFD front panel before ever dicking with remote control. I told him as much. At least convinced him to stop bashing the wrong party.
