Hi Jim,
I found myself here thinking about a similar solution, but i am out of my normal zone. How would this setup handle manual turning of the leadscrew handle? I assume one wouldnt have to overcome the holding torque as power would be off the motor, but arent there issues with turning over steppers and it driving a voltage back towards its drive? Is this somehow accounted for here? Apologies if that is a stupid question, as i mentioned i'm (as yet) out of my depth on this.
Thanks,
Kevin
There no stupid questions at Hobby Machinist and this is a really good question.
The best way would be to simply unplug the motor (between the motor and the drive) when using the machine manually. This could also be done with a 4 pole switch or a relay. It is possible to fry the drive by turning the motor, but it is unlikely that you could turn it fast enough by hand to do that.
