Hi
Steppers were these:

They microstep beautifully at 9 volts. They do not work well at voltages much over this. To me this a is OK as it means that a power supply is really easy to find. Some motors need 24 volts which means lottsa $ for a power supply.
They are fitted to the G11 and have made a huge difference to my PE, not so much in the magnitude (though that is less) but all the high freqency gearbox noise has gone. Very smooth, very repeatable. Will be trying out PEC programming soon....
Couplers were these:

but they do need to be turned down on a lathe. If you can't do them PM me and we can organise something as I have a lathe.
