Just curious about the electronics... Any infos / specs on the control board?
2 boards. Um2 board with some heavy changes on electronics to fine tune it, new resistor on feeders to remove a stepper weird effect called zebra lines or alike, a new brain with linux totally in control of the board with ssh access to the firmware. Now the brain is called 'griffin' and is written in python running on a a20something board totally opensource stuff.
I was able to brick it the 4 day and unbrick 2 days latter using a cable to debug the new brain (I did some nasty linux editing to brick it XD). Also now you can actually make Scripts! that run on python to control the machine.
