    Doddy: If you need help with this I have my Myford s7 running on linuxcnc but through a mesa card with 2 mpg's so I can use it manually.

    I am also setting a lathe up for a forum member with a PP running linuxcnc with an encoder (just A + Z) for threading you need 2 pins on the PP for this so three left for homing switches if you need them (I don't bother)

    Doddy,
    Using parallel ports has to be on the way out, it's still a cheap starting option for amateurs but it can't last. Trouble is there are now several other options available at various price levels with no clear winner for the inexperienced to choose.

    Clive, much appreciated, I might well bend your ear. Encoder = shaft encoder I take it?, that was my plan, with one limit switch to avoid crunching the stepper on the cross slide (I foolishly went for a low profile stepper on the rear of a mount plate instead of the jefree front mount and it will impact the handle for the split nut engage lever

    And for those of us who only have ten shillings available for this specific part of the project, the seventeen-and-sixpence solution is not an option. And having now totally confused all of our non-UK readers and all of our under-50-yearold UK readers, I'm done for today.

    I actually made a 64 slot disc with slot opto sensors. https://photos.app.goo.gl/66KmdtD7TzUziNih7 you have to be able to move the sensors around to get the correct sync

    edit: if I was to do it again I might have used a rotary encoder (it would have to be low count with a PP) But its been working for at least 3 - 4 years

    +1 - If that happened I'd likely bite the bullet and go Linux - after my recent experiences with Windoze 10 I'm kind of over all things Microsoft. As I have Balazs from CNCdrive's email I might just suggest it ;-) - maybe others can do the same?

Going motion controller tends to kick the low-cost solution into the long grass unless you already own such a controller. I've been looking at the thin clients for very much the same reasons as Voicecoil, for a lathe install. Because UCCNC is not particularly lathe-friendly I'm now looking to avoid the whole mess of windows and trial LinuxCNC for the first time, but for that I think I need a machine with a parallel interface. I've got a couple of old desktops - not an ideal form-factor to bolt onto the side of a myford cabinet, but it's starting to look like the best, cheap solution for me.
    Check out the HP T510 thin client. It has a parallel port, has a dual core CPU that benchmarks twice as fast as my old XP machine, can be found with 16GB flash and according to parkytowers takes Linux well. There were one or two on the bay of fleas for £50 ish last time I looked.
