    I'm running off a 36v supply with a pair of 6A outputs...

    PSU has 3 x 24V 10A outputs. I had most of the bits kicking around, just had to print off the plastic case. Just kept checking for square as everything was tightened up.
    If it don't fit, use a hammer to make it fit....

    A much flasher PSU than I have!
    Did you have any difficulty getting the rails dead parallel and level?

    Quick progress report on 'The Beast'. Now at the rolling chassis stage, got to fit GT3 pulleys and belts, progress made on electronics and psu.โšกโšกโšก

    Sounds like you might not have been waiting long enough for the Arduino to boot and load GRBL, so the port refused to connect, and then just stayed 'busy'....

    If it happens again, try opening and closing another port, and then going back to 8. That seems to reset the flag...

    I abandoned the job yesterday. Just come back to it now, I shut down all the open windows, restarted my PC, plugged everything in and away it went. I just tried 1 motor at a time and all is good. I can now wire the rest of the drivers up, make some new stepper motor leads up to the correct length, draw a nice box up with DSM and print it out, Happy days!

    Aha - I get that a lot. You have told UGCS that the Arduino is on port 8 at 115200 baud, haven't you?

    The first thing to note is that the Arduino takes an age to boot up. So plug it into the com port and wait a good 30 secs for it to settle down - or look at the lights on it and wait for them to show that it has booted and loaded GRBL.

    Even after that I can still get difficulty connecting. Do you have several available ports? I tend to get UGCS to open another port, then close that one, then open the correct one, and that often helps the connect.

    I suspect that interference on the line can cause quite a few issues - I have ferrite line filters at all available points. But the big problem I had was realising that the Arduino retains its settings over a power-off, so you can't just reboot and start again from scratch. If you have set it up incorrectly (as I did several times) you have to re-set it up properly before it will operate... and the com ports also seem to remember that they were busy and refuse to become free...

    'How did you get on? We are all agog here...!' Well, everything lit up as it should, but zilch as regards motion. I have an idea it is a software issue I am having. GRBL uploaded without a hitch. When I try and connect Universal G Code Sender, it says 'can't connect, COM 8 ( Where Arduino is connected ) is already in use, access is denied. I am assuming that the Arduino needs to be on the same com port as UGS... Getting splinters in me fingers from scratching me bonce now...
