Several versions of ESP32 now, so will this work on all of them?

I haven't tested it, but I think it can work with any 2-core 240mhz version

That pcb in the first post, was it you who developed and assembled it? The pcb looks beautiful....
Haven't you tested the link files on any ESP32 model?

yes, I designed the PCB and had the PCB manufactured by a company.
The linked files were tested with the module shown in the picture.

Wow, cool. Will you share the PCB files or is it just for your use? Abusing it a little, could you detail how you recorded the firmware on the esp32 and how you installed the driver and hal on linuxcnc using platformio??

This is now I think the 3rd stepgen firmware for ESP32

wouldn't it be good if you tried to combine your projects and make one of them, the differences shouldn't be that big and it would be easier for the users to decide.

You could also combine your resources better this way.
maybe even merge with remora.

but i can also understand if you want your own project :)
