What errors are you getting?
the software works very well, and will alow you to get very smooth motion and reduce resonance to a minimum.
what RS232 cable are you using? and are you going from native RS232 or through a dongle?
You may be better to just do the Auto tune till you get it running right, then do the mach 3 motor tuning (set accel / de accel up) and so on.
after this if you want to tune more, then use the software, but in most cases it is not needed.

Had it up and running with mach doing some jogging about and it jerks around like a jack hammer on the Y and Z stalls all the time even with low speed/accel. The software from Leadshine doesn't work for me either and throws up errors then crashes when reading or writing data to the drives.

Why didn't I spend the money on a nice long holiday instead!
