Remora - ethernet NVEM / EC300 / EC500 cnc board

Thanks for sharing, it will definitely help others. You've picked up LinuxCNC quickly.

I didn't check the voltage on VSO when Linuxcnc is not running, I didn't think it would be useful, but I can do that, it'll be just a minute to do so.

My main issue is of course the output voltage when the system is up&running, as I have everything else working fine with my board (movement, limits, inputs, outputs to enable forward and reverse rotation of the spindle, etc.) but the analog 0-10V.

I'll try to get a picture, but this time I'll leave the lid off, in case I need to access it again. I'm also guessing if, to solve the issue, I'll have to flash a new version of the firmware, I'll have to free the board again... Maybe, without the lid on, I can leave the serial headers soldered on.

I'm getting an oscilloscope, will be here in a few days, so then I should be able to understand what is going on with the VSO output (it's a shame there are no other float pins on the board, just digital ones).

Thank you

Thanks, Scott. I kind of cheated. I used the step config generator to create a working config for a parallel port. I wanted to see what a working config looks like. I compared the parallel config against your sample config. The spindle stuff I got from another post on here. You sent my the input and output numbers. I verified everything with my multimeter. I think most people on here probably have a technical background. This isn't for your average sane person.

You would be amazed at how many people come here claiming to know nothing about electronic/electric/cnc and end up with a working machine in a very short period of time.
A bit of reading and patience and following directions goes a long way to the target.
Analyzing stuff as you did is the best way to a working machine and a wealth of knowledge.

Here are the pictures of my board, I hope they can give all the info needed.

STM32F207, that is the micro controller, so probably should use the firmware for it.
Also might want to wait for the more experienced members to reply as i had no time to play with Remora, yet.
