2.6.66

Dual Extrusion printing. Using PLA as support material in 1st extruder. When last layer of support is reached, temperature of extruder 1 temperature is reduced to zero while still printing last layer causing filament to strip and last layer of support to be incomplete.

Can you share your gcode file or share the last layer gcode lines and beyond? What filament slicing profile are you using? Were you a beta user? If so, did you clear your cache when upgrading to stable? Also, which printer and dual extruder version are you using? This information will help our support team. Send it in to LulzBot.com/Support.

Was a Beta user with many forum feedback comments on Dual extruder issues.
Cache was cleared before installation of 2.6.66 per instructions on Lulzbot website
Taz 6 is the printer–original launch version. Firmware is the AutoUpdate from 2.6.66
Dual extruder is custom built from Flexion units…many hundreds of parts produced…when issue happened I immediately, manually reset to 215C and it returned to temperature but not fast enough so it is not a hardware issue. Printing with same gcode file again now with vigilance as I need these parts ASAP.

gcode is attached
