I have just about got the extruder installed and wired, and the heated bed is working, almost.  The bed controller melted down due to a cheap under rated connector, and the extruder stepper motor is bad, another motor runs just fine on the drive.  I realized the QuBd extruder I bought was a really poor design and had to redesign it before I even mounted it. So I am ready to finish up configuring it, and I have questions about what others have Mach 3 controlling and how that works out.  Anybody got a Mach 3 printer running?
Thanks,
