Thanks mick
Mike No they are not trash, just not suited to the power supply and drives these motors have inductance of about 7mH, per phase now the ones that I use and a lot of others are these:-http://cnc4you.co.uk/resources/60BYGH301B.PDF which have an inductance of 3.2mH (less than half) I run these at 68V. As Jazz has said that kit has its own software and not Mach3.
If it is your intention to build another machine in the future it might be worth it to sell your kit and start again. But first have a go at machining and having fun making a few parts with the 6040.
If you really want to change the drives in the 6040 for the one's in the kit then either get a new power supply linear type or build one (if you are confident with mains voltage).
Either way we can try and help you through this learning curve. ..Clive
