gr5, I did move the serial cables around, reconnected, seperate them.. but no luck....
I have the original UM card as well as a makerbot sd card and another one.. all working on the other printer. I also reformat to see if it will change.. nope.. and it's not a filename issue either...no special character.. a.gcode or bldg11.gcode lead to the same results.... any idea to troubleshoot ? I guess I need to find extra serial cables/ ask UM to send me new one
Did I mention it used to work before
