        That’s a shame !
        I’ll have to make my own dxf anyway now as I have just milled the plates using your Gcode download and the motor holes do not line up – purchased the motor from your link but BangGood probably changed the supplier or something.
        Not to worry it’s all good practice milling – excellent video by the way.

    Also I’m having trouble to access nc code for the switch pcb… I have downloaded all your files from here but none of them is nc file. Can you please share full nc code for that pcb.. I’m a bit lazy to do it my self when you already done it and proved it
