Good night friends! The problem of the error was solved, I acidentally pul a wire a few days ago, and the weld of Encoder B on the SUB Board has broked, the copper rail was interrupted, so the signal for automation worked, but not for the printer, so I got the error 0xE4 or E4H, Now I'm putting all the parts together, and let's go to test it with open DTG code, because my code give this aditional step on printing, about it, what can be the motive?
