I may try that. Though, while it does still rotate when it's not engaged, it will stop if it hits any resistance.... though, while that's great, still shouldn't have anything in it's way, that's a problem in itself.Take the spring out, and make it stay engaged, with the spring the handle still goes whipping around anyway.
I'm planning to hook up some stepper motors for my power feeds, x and z at least... though step one for me at the moment is just to get it plugged in... I ended up running a dedicated 20amp circuit so I didn't have to run a 50 foot extension cord... ended up about the same price, since I'm running all my lines.
