Well I've been using the machine for real for something like 4 weeks now, so thought I ought to report on what I ended up with computer-wise. My original plan to run UCCNC on the HP610 that Doddy kindly gifted me (or an old Dell I had knocking about) came to nowt as they wouldn't support the version of open GL that the latest version of UCCNC uses, so I swapped out for the Dell/Wyse D90D7 I was using to run my audio test gear (£30 from the Bay of fleas). Some probing about revealed that you can't easily get these devices to run any other version of Windoze apart from what they came with, so I set about trying to make it work on Windoze CES7. I deleted all the networking stuff and had a few fights with the FBWF (File Based Write Filter) that's used when it's a thin client, but after that it seems to work pretty well. To change anything you have to log in as Admin, but when it comes to actual machining, I just turn it on and plug in a USB stick with the G code files. If I wasn't working remotely from my design PC I's have had a shot at networking it, but since they're 3 miles apart we'll leave that for a bit.
