Offline G-Sender

[harinderbhinder]

I found this repo for offline grbl controller
https://github.com/LEKN-TECH/G-Sender

I'm using grblhal on custom board using stm32f401
Right now i'm using motors(XYZ) and limit switchs
what pins i can use to connect arduino(Tx, Rx) with stm32f401
so i can run machine offline

It depends on your map file - these are the pins currently supported (up to 3 ports can be defined). An example.

If the offline controller is of the "man-in-the-middle" type you will have to switch to UART comms instead of USB, if not enable MPG mode and use a switch for the switchover signal - or modify the the offline controller to send the switchover command character.
