Re: Dual Extruder V3 used as single extruder

Hmm... the two toolheads should be swappable. You'll have to flash the firmware on the printer each time. As for getting the nozzles level, comparing the extrusion thickness of a calibration pattern works best for me on the TAZ 5. Lock in the initial nozzle height then adjust the second (T1/E2) nozz...

Re: Need help with "pigtailing" while printing

If the extrusion comes out of the nozzle straight, its probably an adhesion issue with the bed. Clean your print bed with alcohol and scotch brite pad. Lower the initial nozzle height using the z-limit to help the adhesion (try half a turn at a time until the extrusion sticks)

Re: Dual Extruder V3 used as single extruder

In S3D, there's an option to use T0, T1 or Both... when configured with a dual extruder.

Re: TAZ5 Dual V3 loose nozzle

Cold pulls are really hard to do with the gears and curved filament path of the dual v3 extruder body. You can possibly do it as the nozzle cools down. Try this: - Heat up extruder to normal filament extrusion temp - Turn off extruder or set temp to 0C - When hotend temp cools to filaments min-temp,...

Re: Dual Extruder V3 used as single extruder

Leave the unused extruder off. No sense in having it heat up filament and possibly creating a clog from prolonged heating of the filament. With S3D you can specify one extruder or the other (leaving the other off). Not sure how to do it in Cura... you may need to set the non-used extruder temp to ze...

Re: Dual Extruder V3 - Hobbed Shaft Gear Stripped

No... sorry, haven't tried to figure out a torque value. The single screw under the two longer screws is the primary for holding the plate on. The two longer screws act as an axle for the gear. The assembly instructions state to ensure the large gear moves. There are nylock nuts on the back... I've ...

That's interesting... maybe they "fixed" the system with a thicker steel plate...

Re: Thermal runaway

Check the thermister... looks similar to the bad crimp issue.

Try to re-crimp the two pins on the connector with pliers or a dab of solder. Or just get a new thermister and swap it out.

Re: Thin Cover ABS without Warping

A heat lamp or small desktop heater should get the ambient temp in the enclosure to help mitigate the warping. The brim works to prevent air from seeping between the print and the bed. Here are ideas to reduce are from seeping under the print: - Adjust the initiial nozzle height closer to the bed wi...

Dual Extruder V3 - Hobbed Shaft Gear Stripped

Here's an interesting one... The big gear on my E2/T1 stripped at the hobbed shaft. The stepper still spins the big gear, but the hobbed shaft does not advance filament. Since the delrin gear is press fit onto the hobbed shaft, the metal splines defeated the plastic. Here's a clip demonstrating the ...
