this is with my new kernel parameter. Youtube and stress test on.

Thank you for the reply Daz, and the offer to help

I now have what appears to be a successfully flashed and converted ST to DAP-link.

Now I am at the point where I need to hook this newly converted DAP-link to the NVEM controller. Is there a wiring schematic somewhere or something that tells me which pads on the controller get which wires? The pads are not labeled on the controller.

I was just going down that road, I found a post where it was talked about, For now I did this:but I would like to try to add: rcu_nocbs

can you share your lspci result?

Thanks. I was hoping to use the "emergency off" switch plate from our old oil burner, but I guess I tossed it at some point. So I "had" to paint another one red.

It's a double pole switch. One half turns off the spindle's outlet, the other half triggers an e-stop input on the Mesa.

Huh?

Please clarify.

What exactly do you intend to achieve?

The ping times are not terribly important _unless_ packets are dropped due to timeouts.
Default timeout setting is 80% of the servo period so those times look fine for a 1 KHz
servo thread.

Ok so I just checked and yes it has them on both sides. They are contact switches and they both work. I have pictures but I don't know how to send them.

Have you tried isolating the CPU cores?

I have the same processor, but a different motherboard, and the results are better.

It is possible that your problem is caused by something other than delays, but it is worth trying to improve the result.

 

The E-Stop was cool!

Yeah, where to start looking?
When you turn the servo motor (if possible) and look at the relevant pos-fb pin in halshow, does the pin number count up/down? What value does the lcec.0.xxx.controlword have?
Vendor id and product code from "ethercat slaves -v" match the vid and pid fields in ethercat-conf.xml?
Any error messages from linuxcnc at startup, or errors in "sudo dmesg" that can help?
 

Use "Output 3" and "Output 4" on the digital out connector to control the servo.

The MX3660 has its own breakout borad that outputs a filtered (buffered) signal for pins 8 and 9.

Connect your servo to those.

There's no need for an extra breakout board.

S-Curves would be nice.

Constant acceleration causes machine wobble.

Explain.

Did ya fix it?

Hello, first, you need to get yourself a CMSIS-DAP probe. You can buy one on eBay, Amazon, or covert an ST-link probe. Here is a line to the thread how to do it.

Once you have the probe, you need to upload the firmware, I will send you the commands later when I have a moment to take a look into my notes.

Once you have the new firmware, then you can follow the instructions from my post above:
