i use the tablet to download, slide and control the printer with the touchscreen or web browser, is connected to a radds board by usb with repetier firmware.
The tablet is an dual core processor with 2gb ram, it is overpowered to simply run repetier host. This Chinese tablet are pretty cheap and powerful. I like more this solution instead to have an raspberry or a similar board to have an web interface. The repetier host give-me all the necessary tool to print, no need to have a pc.
So far the MPCNC work was expected, the pieces produced have the correct dimension. The only difficulty i have initially was to have the pieces to cut leveled in relation to the router. To solve this i have build a rectangular aluminium structure that can be easy leveled by four M8 screws.
