As I understand the current (11.2016) GO protocol for PiezoDN, GO is printing simultaneously with ink which is confirmed by looking at the master .quad(s). Of course I can't find it right now but I recall Jon commenting that there is an advantage to dedicating 2 channels to GO. What is the advantage of doing this and is the correct setup to copy LLK (GO) in the .quad text file and paste it in an unused channel which would receive a cartridge of GO?
BTW, the 3 intermittent channels on my latest donated 9900 are coming back quickly. LK having come back early on now seems reliable. LLK and Y are back but I am still not convinced they will remain so without further maintenance. I have moved GO from LLK to Gr and would duplicate in Or if dual GO is the recommended protocol.
