Remora - ethernet NVEM / EC300 / EC500 cnc board

Following up (have been discussing this on discord also with Cakeslob):

- Here's a video of it doing its thing. cdn.discordapp.com/attachments/970073318...ID20240401112425.mp4 . Please ignore the inappropriately small temporary monitor.

- It only affects the X axis, have tested Y and Z

- Loading the attached "ec500-rt1052.txt" example config stops the behaviour (this config does not use DMA Stepgen)

This makes me think there's a bug in the DMA stepgen. Though Cakeslob did also point out that the X reported position is bouncing around while this is happening.

it is a EC500. Conn light is off. When I make a download via upload_config.py I see the conn LED short blinking.
I plugged an USB2serial converter directly on the plug on the EC500. I don't need any any pin layout changes?

Hey Peter,

When you run Linuxcnc and bring the machine out of software estop does the conn light come on? At the moment Linuxcnc must be out of software estop to establish a connection with the board, Scott has indicated he may change this in the future so that Linuxcnc stays connected to the EC500 even when an external estop is tripped.

If you can't get the conn light on make sure that you have the eth3.0 component installed and included in your hal.

The 6 sticker on the EC500 just indicates it had the 6 axis config loaded on it from factory. Same hardware as the others.

Hello, I have HLTNC AC Servos and would like to use them with the EC500 on Remora. The question is, which config can I use as a base for this? Unfortunately, I can't find any information on this and would be very grateful if you could help me out or give me a tip.Here is the link to the motors used (z comes with a brake) and the link to the manual.

 Thank you very much in advance.

Halo Cold Turkey,
which is the estop-pin?
how does it needs to be connected? At the moment I have the naked board in front of me, only RS232 and 24V applied to IO and System. I miss any response on the RS232?
when I press emergency-off in LinuxCNC then I can see a short blinking of the CONN-LED.
Remora-eth-3.0.c is installed via sudo halcompile --install remora-eth-3.0.c.
Any ideas where is the problem?

You don't need a physical estop connected. Just need to have linuxcnc running and the estop button in linuxcnc disabled to establish connection.

I have not used the RS232 on the EC500 yet so can not help you there
