Here's what I was thinking of: http://www.protoplant.com/stepperature That page has links to the circuit, board, and code. It looks very well finished, and I have little doubt that it works, but it includes this note: "Stepperature is not a position encoder. Because of the small analog signal use

What's the maximum allowed cable lenght for the DB25 cable between 5i25 and 7i76 with mesa hostmot2 firmware? Is it only the 3m sold by mesa? Axel -- Wir verwenden ausschließlich blaue Elektronen aus biologischem Anbau. -

Re: [Emc-users] Using stepper as encoder.

Unless you are going to implement this in a commercial manner, I wouldn't waste your time trying to do this. Even commercially, I doubt the idea is viable. If it was, I suspect that most of the stepper drive manufacturers would include absolute tracking in their stepper drives. I bought an

[Emc-users] New/Used motherboards

Was wondering if anyone might have a need for some new/used motherboards. We have 4 Intel D525MW w/Atom processors, and 4 Gigabyte GA-D525TUD w/Atom processor, boards we are looking to offload. We bought surplus, and now we realized they weren't enough for our machines so I am upgrading to ASROCK F

Re: [Emc-users] Using stepper as encoder.

Well, the main reason is that I have a box full of stepper motors and no rotary encoders. I'm purely a hobby guy so I have tons more time than money for projects. The second reason is to make one do double duty, sense how far it moved and then move back to where I started. Not sure if that's

Gary, Thanks for the offer, but I'm just thinking about options for a project way out in the future. Don't know if I'll even go that way. Just wondering if it had been done or if I was going to be on the bleeding edge doing it. Raymond Julian Kettle River, MN The things we admire in men, ki
