ESP32

[Mixa778]

Hello. Please tell me, does the FluidNC ESP32 controller work with the program?

[Harvie]

bCNC does not run on controller. it runs on PC and communicates with controller.
As long as the controller is equped with firmware implementing compatible version of GRBL protocol, it can work.

For example GRBLhal https://github.com/grblHAL
should work on several different controllers including esp32 and last time i've checked i was able to get it running with bCNC.

i've never tried this. but at first sight it seems to be based on GRBL, so chances are you will be able to make it work. let us know.

update: aah. now it rings the bell. the bdring guy previously made some esp32_grbl port and this is new version of that. that should work i guess.

I use FluidNC with bCNC and it works fine. Better than UGS.

Hey. I'm using the MKS Tinybee board. Everything works as it does on the Arduino. Plus I have added a 4th rotary axis. No problems with probing either.

Thank you!

Thank you!

I'd like testing this option!

Do you know how to join one spindle for router app on the tinybee board?

[RokyBafal]

I have several types of spindles set up. I am currently using RS485 for the spindle and PWM for the laser.
