Grbl Controller supports the AlaMode in version 3.3.8

I’ve fixed a problem with Grbl Controller where it expected Grbl to reset upon serial port open – some devices like the AlaMode initialize once and when you connect, there is no version response. The fix involved sending a Ctrl-X if no response was detected.

The AlaMode is an Arduino-compatible board that stacks on top of the Raspberry Pi and communicates serially through the GPIO bus.
