Hello,

My CTC Dual Extruder printer doesn’t read sd card for some reason so to fix it I have decided to update the firmware to sailfish. The current firmware is 7.4 internal release 001 whatever that means (I believe it might be a modified fork from sailfish). However I can’t update the firmware no matter what I try. The board seems to have atmega2560 with reset button but the flashing process just freezes whenever I hit upload in ReplicatorG sailfish 40r33 and have the replicator dual selected as machine. The board I think I should select in the flashing process is Makerbot Replicator 1 with ATmega 2560. Has anyone successfully updated the firmware to this thing?
