[Emc-users] AC Servo ?

I have a Servo that has an undocumented feedback encoder. I am interested in trying to decipher it. Is it feasible to run the servo without feedback connected, and put a digital storage scope on its outputs to capture the signal? It is an incremental encoder that has quadrature and

[Emc-users] 7i77 Field Power?

I was going to start working on putting a tool touch probe on a machine with a Mesa 7i77 setup. (I was just going to try a wire clipped to the tool and a touch plate for a start.) I pulled out the multi-meter and started poking around to try to figure out what exactly I wanted to do and

Re: [Emc-users] 7i77 Field Power?

This is on a machine that has been working fine for years. (and still is working fine.) I'm just a little baffled by how the 12v+ is floating right at ground, and the 12v- is -12v below ground. I did a little more poking around, and tried to check for current between the DC- and ground and the

Re: [Emc-users] joint-axis question

Aha! stat.position must return a tuple of *axis* positions, not joint positions as I thought. I guess that detail did not affect me before because axes were interchangeable with joints in my code. I see that stat has a new attribute called "joint_position", I guess for consistency it might be

[Emc-users] joint-axis question

Greetings all, I am a bit bamboozled at the moment, maybe one of you can help me out. I use a custom LCNC UI and I am trying to convert it over to support joint-axes so I can play with 2.8 pre. I just about got everything working last night for my basic XYZA config, but have hit a road block
