    I also wonder if Linux is more reliable than windows (Especially when using USB) especially a Linuxcnc Live cd? I have no idea if you can get Mach 3 for Linux.

    Chaz I'll be interested to see if it was a crossed cable causing your issues, fingers crossed for your weekend movements ;)
    USB serial works, its low baud rates.

    Mach 3 for Linux, no. There is Linux CNC which is meant to be good, but won't support my cslabs stuff as far as I'm aware.

    Thanks, will update over the weekend.

  2. RS232 is only used to set up the kinco ac servo driver using the kinco servo software, it has nothing to do with cnc.

    Is the CNC ran through Ethernet? I think I must have missed a link somewhere along the way

  5. yes, he uses the csmio-ip-a that links to the PC with an ethernet cable.

    So I tried to do the 'double up' with the limit switch for X. Make it home and limit. It goes home, but then when you try and drive the machine manually it says 'limit hit'. I know there is a manual override on the settings page, will try that.

    So, managed to make a small cut, nothing exciting. I need to sort the table. X and Y limit switches mounted and wired in. Having an issue with my Y motor holder, its not 100% level and causing issues, will sort.

    Any thoughts on what I could use as a table? Ive seen alu T plates and similar for sale on ebay.

    Argh, good progress, getting tuning right and then with the limits / home switches I was doing some test. I ended up somehow going past the X ++ endstop which has fortunately only cost me lost time as I now need to repack the ballnut and some of the cart bearings. Could have been a lot worse. Not sure why it ignored the limit switch.

    I was setting the X and Y axis to be reversed as they are the wrong way around ( + and - direction ). Do people normally do it on Mach 3 or reverse either the -10 to 10V or swap motor leads (and encoder feedback)?
