Hi George,
Yes that's the gamble with the all-in-ones, but I'd been using it for 2 years before with no problems. Good price, easy to use, and does what I want in terms of speed etc. My own stupid fault for breaking it when connecting it up to machine mk2. Hopefully when it's back with me again I'll be up and running again.

I did look around at the other drivers when I broke this one in case I'd killed the whole board, and I noticed that the Geckos have a feature to prevent incorrect stepper motor wiring. Also Roy now does the system4, with seperate plug in driver boards for around £110 complete which I think is good value, and I'd probably have gone for that.

There's alot of supplier complaining on this forum (some of it justified) so I thought I'd even the balance with a bit of praise.
