Clive,
That looks exactly like the one I bought. I had to wind up the ratchet to max to get the small ones to grip but the biggest problem was them shearing off. One would break as I was putting in the one next to it. I persevered out of bloody-mindedness but I don't think the result is any more reliable than just putting the twisted wire into the terminal.

I note your technique of crimping twice and it might prevent the breakages by not crimping tight up to the plastic surround, leaving a short length of unmollested metal tube.

Anyway the connections all seem to be working for now and the next time we get some rain (I'm too busy gardenning while the sun shines) I hope to get the homing and spindle control all sorted out. Acceleration, max speeds etc. have all been copied over from my LinuxCNC setup so I'm hoping for a smooth transition.
