FlexyDualyyyyyy pretty stoked. Got to add this onto one of my TAZ 4s at work today.

I’ll be honest. At first I was steering people away from dual extrusion in general after some trials on my own and my experience with the rep2x. But this thing and slic3r 1.2.5 has really redeemed duals for me.

1.5 hours start to finish to wire it and load the new firmware changes, and calibrate it. The calibration script and the Lulzbot dual extrusion calculator made getting the nozzles lined up a breeze. And seriously, who ever decided to put the nozzle adjustment screw on the from so the nozzles can be leveled on the fly needs a beer from me. That makes things so much easier.

All in all I’m super happy with this thing and its made me excited for dual extrusion again.

Thanks @LulzBot ​ for continuing to be awesome.

I’m building a dual extruder for my taz 3, and I must say, it’s definitely looking pretty cool. Do you have a link to that calculator?

3

Its in the OHAI-kit in the calibration instructions but I’ll post it later today

Looks nice. I still don’t fully understand the flexydriver (and the cost of it)

Does it just have a ptfe tube that runs on either side of the hobb to minimize open space around the hobb? Also does it only work with 3mm filament?

5

have you tried to print anything using the ninjaflex filament? that stuff is what is pulling me toward updating my practically brand new TAZ4 to the dual extruder update… so hoping to hear some feedback on printing ninjaflex. thanks

@Mike_Kelly_Mike_Make ​ the flexystruder has a PTFE tube that runs the full length of the extruder with a notch drilled out for the hobbed bolt. This supports the wet noodle consistency filament the full length. Lulzbot only works with 3mm so that’s all it works with. It could be converted or made in theory for 1.75. One of the biggest high points of @LulzBot ​ is their fully open philosophy. So you could down load the models, modify and print a 1.75 struder if you want and in the OHAI-kit there is instructions on building it.

@Jonathan_Rochelle ​ the yellow is ninjaflex. Its an awesome filament. Temperamental as hell but super fun.

I just was confused as to if there was something more to it than a greg’s wade extruder with a notched PTFE tube. I’ve been looking at the design trying to determine if there was something that I was missing.

Look at the OHAI-kit. It has a full tear down. Its not too different. The main cost is built around the fact that Its a drop in replacement for the main extruder. 30 seconds and your swapped from ninjaflex to a normal extruder and back again.

I just realized you probably have no idea what I’m talking about. This is a work instruction site Lulzbot setup. I think its mostly for their staff but its a great resource.

Yup hadn’t heard of that. Thanks for the link!
