Phil, I`m in no doubt that I`ll crack on and upgrade the drivers and have a more 'professional' system using Mach3 - however, I think I may well order the Leadshine drivers from China and in the mean time, I`d like to give Estlcam a go especially since I have an Arduino Uno kicking around somewhere, it won`t cost me a bean. However, to use it, I guess I`ll have to identify the step and dir for each motor - but after staring at the large board, I`m not sure what I'm looking for or where! Based on my previous experience of CNC, I think I`m right in remembering that there was a step, dir from the BOB. However, this is running serial cable in with only three wires from the PC output and then if there is a BOB built into the motor, no idea where to look.
Anyone any idea where I would tap into step and dir ?
