Hello everyone,

I am currently using the Taz 5 Dual Extruder V2. Currently, we are trying to get the dual extrusion to work, but whenever we try to print something, it seems as though halfway through the print the printer will not switch extruders correctly. So when extruder T0 is supposed to be printing, T1 is printing elsewhere on the bed. We calibrated everything according to the Lulzbot guide for the dual extruder. Any ideas on how to go about fixing this? I am willing to provide what other information that might be helpful for solving this problem.
