Hi I just wanted to share. I have recently purchased a rock pi x to control my xcarve. It is the same size as a raspberry Pi but you can install full windows system on it. Basically a mini computer with passive cooling so no fans or cooling to worry about. Just thought I would share. I know there are a lot of people looking to use tablets. I think this is the best option. Basically a full computer in the size of a pack of gum. Cost me about 125 cad.
Any questions, please ask.
