I know nothing about the creators firmware.

Is it pure makerbot - or is it adjusted by flashforge ?

Apparently I have both version 1 and version 7.2 (think that's what it said)

Then there's the little voice in my head (the one that makes me root android stuff) that says: if you changed the firmware you could get repetier host and cura to talk directly to the printer.

The more I use makerware - the louder that voice gets.

Are there any other firmwares out there I could use - and if they don't work, how easy is it to reflash with the one I've got at the moment ?

Having bricked an iphone in the past - I'm not going to flash unless it's risk free :-)
