Yep. There's a retrofit that someone did where they took a Bridgeport VMC that runs the same motors / encoders and put new DC drives and ran with Mach (spit). A few months later they ditched it all as it wasnt stable and went with AC Servos. I dont think I'm far off that option at this stage. Run as...

Looked at the Z, was thinking, there's no wires from the head that's unmounted and there is an encoder on the Z motor. ERO115.

So, machine is at home. Still moving into position and then need to find a solution to power it. I did open the one rotary axis. There's a Heidenhain Rotary Encoder type ROD 456.0000-600 on the back of it. I Cant see where the cable goes, but doesnt look like it goes to the controller but that is it...

Heidenhain does make signal converters. If I recall correctly, IBV100 and IBV600 series are for voltage-mode sine/cosine signals; and EXE100 and EXE600 series are for current-mode sine/cosine signals. However, those signal converters are generally more expensive than a basic rotary encoder, so they...

page 719 also shows 9 pin connector options as Sine Wave Signal Input.

Page 132 of this manual talks about the encoder types going into the 407 (now confirmed its 407) controller. It talks about signal period, so assume its going to be as you suspect, sine / cosine. https://adegis.com/media/asset/ed4ab66482fbedfb2bba555d13aceb381fb784ba0f64cdbfc4a60991433f89cf.pdf Page...

Hmm. Five-axis machine, and there in your picture are five connectors that look like Heidenhain M23 12-pin feedback plugs. Each plug bringing in nine wires, including four twisted pairs consistent with Heidenhain position feedback (BLU+RED, YEL+GRN, GRY+PNK, WHT+BRN). Because it is Heidenhain, ther...

Suppose thinking through, its not step / direction, so it cant pulse a distance, so yes, there must be some feedback somewhere.

And I took this pic, wanted to see if there was anything that looked like encoder wires coming in. Pity I didnt take more of the plugs.

Can Oak run without this encoder feedback? No. Neither can Heidenhain, unless all it does is move back and forth between limit switches. What exactly is a "Gate machine"? If the Heidenhain control had a DRO position display, and the ability to move to programmed positions, then there is p...
