Might be a good priner controller

[www.gearbest.com]

Has anyone used anything like this device, with windows 10 and what appears to be a decent screen, all at a very reasonable price it might make a good control unit for a printer?

Looks like it would be good as a user interface. I wouldn't want to use it to control stepper motors though. You would have to add a hardware layer, in which case you might as well use RAMPS+Arduino, in which case any cheap laptop will be just as good.

But don't be panicked into grabbing this particular offer. There's dozens of sellers on AliExpress offering the same thing at similar prices. (The gearbest offer will also be shipped from China).

Yeah I was thinking along the lines of host controller rather than hardware control. Might just be neater and smarter than an old laptop (which is what I've got now).
