Sure - Indeed after the hour long laser cut I noticed the piece finished and tgFX was still drawing and reporting movement for another, maybe 30 seconds.
Well, I downloaded this: http://synthetos.github.io/binaries/tinyg-edge-438.02.hex
Just now loaded 438.02.hex but had to use avrdude - could not load from tgfx (below), maybe it does not know where avrdude is.

Prevously tred to upgrade from tgFX, machine settings, update firmware from file, the console reports:
Your TinyG will start blinking rapidly while being programmed
