What would be required to increase the pulse rate to 100KHz for 3 axis ?
Is it a hardware limitation of the esp32?
Cheers.
Russell.

Hey jzolee, Thanks for the work my w5500 and esp32 both came in but in not sure how to implement your .comp and UDP files above. does the UDP.comp get loaded on the esp32 and the HAL2UDP on the linux pc? Thanks for the info

Couple multiple ESP32 be used to allow faster step rates?
e.g. 1 per axis?

this would be a big problem because I would have to have 1 master to receive the UDP and separate it for the other slaves, so I believe that this would cause a high latency and not bring good results!

Check out this ESP CNC board I found for 15USD it just arrived   I will have to dig into the pinout to see if the SPI is accessible.

The point and feature of using the esp32 is that it connects over UDP so there can be a good distance between the motion controller and the stepgens.

If you want minimal parts count then look at AllwinCNC
forum.linuxcnc.org/18-computer/39037-lin...-orange-pi-allwincnc
It has the LCNC motion controller, GPU for GUI and stepgens all in one device. But you'll still need some output protection like you'll find on the Mesa IO boards.

Will UDP protocol not cause data loss ?

Not if implemented properly. LCNC has been working fine with UDP and Mesa cards for several years.

Can you help me with this doubt? would it be possible to put something that monitors the communication between linux and esp32? I say this because I noticed that I see a drop in the communication, the engines being at work they continue to infinity, that is, they will only stop when the communication is established, this can cause a loss of a part for example, this also happens when a interference and loss of communication between esp32 and w5500, I thought of a watchdog to check the connection between linux cnc and esp32.
