    Replaced the linuxcnc machine with a core i7 (Think I need to restrict the cores for max performance) and now I can run the machine fast enough to firing a stall protect consistently which I guess is my upper speed limit. Somewhere around 4m/min with the 1400mm ballscrew which is a little faster than I thought it would do this is no load any faster it makes a funny sound and stall protect I think this is screw whip but hey just guessing.

    At moment I have it running 2.7 used stepncof to set the A step and dir pins to Y and we have as much control as I had on 2.8 lol, same errors firing up but had enough went through 4 pc's before finally giving up and using my fusion 360 CAM machine set up as a dual boot.

    Have the switches on need to configure them as I was checking the switches I managed to pull the wire out the X dir socket on the BOB just enough to not work but not enough to actually be visible spent 2 hours tracing and fixing that this time I put crimped them with ferrule ends they're going no where.

    Worst part about the cheap BOB's is the sockets are just crap you can work with them but I'd rather pay a few quid more for some decent connectors.
