Griff, we used Wago connectors in the ShopBot days, but the recent MM's have been without connectors. Crimped, hard-wired . . . . much more reliable.

The motors don't go faulty...we learnt that there is no need to "un-plug" them. In fact, when we did have something looking like a motor problem, it was a connector problem. Getting rid of connectors was the logical next step.

Griff,
Many MM users have been using the 4 pin XLR for the stepper motor wiring.
