Hi Jaz thanks for the reply, i tried a different usb to serial cable and it all came to life which is great.

it even stops when it hits the limits. Although once when it hit the limit (it cuts the enable signal) then the drive did report a stall. could this be due to it running along (not very fast) and then stoppping dead when the limit takes away the enable? If so is there away to stop the stall, may have been a one off as i havent tested again.

Just really happy all my axes work
