HelloI've been working for a while on retrofitting a “small” Mecanumeric / Charlyrobot milling machine (the second one is the real manufacturer but they merged) at my work.

I work in a fablab in a high school in France. This machine has been at the school for many years, and originally ran on a Windows XP PC with specific software.The motherboard in the machine had a number of problems which I won't go into now, including a slightly scratched tool sensor.....I suggested modernizing it, making it more upgradeable and easier to repair.

So I had a few items purchased, including drivers and a Mesa 7i96S card. I reverse-engineered the wiring and managed to implement it pretty much as I wanted. The control panel was made from MDF using the big CNC machine, an Arduino using the great Arduino Connector project and a salvaged industrial touchscreen. I've added the ability for LinuxCNC to detect the opening of the cover to prevent the execution of a program. And to deal with minor oversights, I've added a relay to activate and deactivate the vacuum cleaner.
Finally, I've designed a small, unpretentious tool probe (which I can show if you're interested) with a microswitch and 3D printing.

Does this look ok to get the encoder PV1 counting? PV1 should be the MPG socket. I don't know if I have a hardware issue or code issue. Also does the nvmpg.so need to be compiled first? I'm using an adum1200 to bypass the opticouplers. PV1 does not count when I move the encoder in Halshow

Hi, are you using the nvmpg or just an encoder?

The nvmpg component does the communication for the screen updates and button press receptions. The nvmpg LinuxCNC component needs to be enable in the ini file to use the remora-nv-mpg.hal file. Encoder pulse counting is done in software on the LinuxCNC side. So slow speed counting.

Encoders require the QDC module to be enabled in the config.txt file.

That's very kind, thank you.
