Hey @vicious1 - turns out after doing more diving via @Dreyfus UART test topic

Uart bridge help

FluidNC runs the UART at 1Mbps by default. Yes, but opposite what you’re suggesting. I believe the ESP-32 bit-bangs the UART, so when you’re transmitting data you’re hanging out in an ISR. That’s fine if you are sending a byte or two and the system is pretty much idle. It’s not fine if you have significant data flow and the system is otherwise pretty busy. You want to get into and out of the ISR as friggin fast as you can to save the processor to handle the real work (running the motion c…

It looks like we MIGHT be able to use the CYD pendant and its’ SD card slot as a gcode sender. This changes the calculus. Walk over with an SD card, pop it in your CYD, use the CYD to home the machine and get set up, run the job from the pendant.

I’ve got to finish my builds to play with this.
