Hey, is there anyway someone can print using just the front nozzle, it keeps printing on the rear nozzle. So far I have tried to print switching the nozzle to 1 on the manage printer, also printing with just the front nozzle with the rear nozzle at 0 F. Finally I even tried to change the G code to use the first noozle? Thanks
Add
T{initial_extruder_nr}
to the bottom of the start g-code in CuraLE
Also check the profile to ensure the “Build Plate Adhesion” extruder is also set to the front nozzle. Search the profile settings for Extruder and change the build plate adhesion extruder to the second one. Keep in mind that they may both be named Hot End 1, so it helps to have different colors set for the filament so you can find it easily. Surprisingly, there is no “Not overridden” option for this setting, so it’s a manual thing to check.
There’s an error in the startup GCODE, where it switches extruders to zero out the position, and zeros out the position of the rear extruder last. It never switches back to the “active” extruder afterward. It’s a legacy toolhead on a legacy printer, so I don’t know if lulzbot will ever fix it. I’ll probably submit it as a bug when I remember, and hopefully it will get fixed in an update.
