linuxcnc-esp32 Software Stepping over Ethernet Using ESP32

After almost two years of studies and dedication, we have the ENG-E2 working with Linux cnc with ethernet communication, we have no latency warnings or connection losses.

That is great!

What step rates can you achieve?

Cost of the board?

I have two projects, with the esp32 using the rmt, I got frequencies of 150khz, without the rmt I kept 100khz, more than enough for the vast majority of people who use router machines, with the stm32 I have a project running at 100khz using the same idea as drive, but this one will be for the future, F407/F429, face about value, look, I didn't want to put this up for sale, but I really want it to work, I say this because I wanted to take that money and help people and animals that are on the street, So I apologize to everyone for having to make this decision, but it's for something bigger, and I hope it works.

Update of our work, gcncE-2 100khz and gcncE-3 120Khz.

gcncE-2 can work with 200Khz, but I kept it at 100Khz because I didn't see the need for that frequency as it would be more than enough for the vast majority of applications.
