I have a flashforge creator x with 1280 chip... im a noob so get more info
I installed sailfish 7.6
dennis I think that's right replicatorg 0040r23-Sailfish gets you sailfish 7.6
after a day and a night trying to get back what was shipped I.E. in I was printing before the update....
and at times wish I didn't update...
im printing but I got 8 things out when I first got it and I'm sure ive burned out the kerpton tape
I was wiping with alcohol after every print . then I went to glue stick but I just tried one from the dollar store and it didn't work, then acetone and abs mixed but that didn't do it
so ya Im not sticking very good now

I was able to go back to the old firmware but it was not creator 1.0/ 7.2 it was just 7.2mighty board
