Bondtech Dual Drive Extrusion Upgrade Kit for Prusa Mini: why is it better? 

If that doesn't work then the Bondtech is a downgrade! The load/unload future is probable one of the best parts about this printer. I've never been able to change filament so easy.

It works for me. Sometimes I have to do an extra purge, that’s it

Not yet! I have taken a winter break in my cottage and I have been busy with another project. I'm testing in these days.

I made this one. If you have specific topics I would love to hear those! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sQ_kwg3XuV0.html

The spec sheet reports it is ready for nylon. Max hotend temp is 280C. For carbon fibre you will need a hardened nozzle to cope with abrasiveness. Welcome to the club! 😀

@@AMakeDesigns Many thanks, I'm blown away with the new materials and the low cost and capability of these printers compared to only 5-10 years ago. Can't wait to jump in! Nice channel by the way!

Yes. Completely.

@@AMakeDesigns Well, I purchased the IFS version for my Mini+ and installed it without issues. First day was silent and I was thrilled. Now I'm getting a small, but clearly audible "yelp" type squeak on retraction it seems. Is yours still silent after long term use? I'm stumped. Nothing obvious seems wrong.

I hear no noise. Did you try loosening the idler?

@@AMakeDesigns I did, but I will continue to try to adjust in small increments and see if I can work it out. It's still far less noisy than the stock extruder, but sure hope I can find the sweet spot I apparently had on the first day of install as it was beautifully quiet. Thanks for responding and sharing your experience. If I find anything helpful out, I will report back for others benefit.

Good luck with that!

Same issue here...

@@AMakeDesigns are you responding to get credit? Real youtubers give advise or don’t both responding.

I try to help when I can. I upgraded the extruder because I was struggling to set it properly. This is the only advice I can give without more details : help.prusa3d.com/en/article/idler-screw-tension_177367

when you are installing extruder you have to test that gear and motor is spinning before thingtening all screws

What issue are you referring to?

@@AMakeDesigns they say some filament junk gets clogged in the extruder?.. im considering a prusa mini as my first 3d printer.. its seem getting a printer is better than having to wait and pay for some1 else to do the print only to realize you need to revise and reprint again.. 3d printer are kinda practical to have at home..

I only had problems with flexibles. You need to tweak the idler tension carefully. Overall it's not bad, it's not excellent either... I would say the Bondtech is a valuable upgrade.

I don't have one. I'm sorry

So far so good! I was testing today with unbranded TPU and works well!

@@AMakeDesigns beautiful! I guess I should build a clone soon

thanks for sharing! I must have missed it.

@@AMakeDesigns you are welcome, but the bondtech looks promising. hope you will make a followup for setting the start gcode and stuff because of the new steps. you cant do it in the firmware sadly

it's in the plan!

Very well. I am working on a followup video but got side tracked by another project 😅

Very happy that you like the video! I will keep working on the music 😉

It solved all my jamming problems. The stock extruder is too sensitive to my taste. It is too reliant on the idler tension. Is it a mandatory upgrade? Absolutely not, but if you have troubles setting the extruder this will help a lot.

Are you sure? If it is I really wonder how they make the 2mm hole for the filament.

@@AMakeDesigns No, it's SLS 3D printed.

That's what I say in the video 😉

It's not a matter of tightening torque but rather of alignment of the two parts.

Well, Prusa's business proposition is around service, tech support and end-to-end ecosystem, they know they will always be more expensive than China. I don't love or hate them, but I liked the Mini experience out of the box. No bed levelling, I just start it and leave, contrary to my Ender that requires supervision for the first layer or two. To be fair we have to say that Ender-3 stock extruder is junk, at least the original plastic one: it wears off, breaks around the insert, loses force over time.

you have got to be kidding me with that last statement.. So you think the insanely terribly stock plastic ender 3 extruder is better then the prusa mini extruder? All printer gear from basically every company in the world is made in china with "chinese hardware"... that doesnt make them bad. The prusa mini is incredible for the price, and you can get clones for less then an ender 3 pro which makes it a no-brainer.

@@raider1284 in fact, by now all the world production of hardware and electronics is produced in China (then of course there are also quality products) Prusa assembles in Europe but most of the components are Chinese. What I meant is ... that sometimes myths are created that are not in reality. In people's minds the idea that all plastic parts are produced by the same Prusa printers is a nice thing, please don't joke !!!! the quality of plastic components manufactured by injection molds is considerably superior, from all points of view !!! Regarding the bondtech extruder, here too a myth is created ... you can get the same type of mechanics by spending much much less (it.aliexpress.com/item/1005001431887581.html?spm=a2g0o.productlist.0.0.65652caaL3MJkQ&algo_pvid= 69d041f9-f8c5-4a66-ae5d-8870b99becdc & algo_expid = 69d041f9-f8c5-4a66-ae5d-8870b99becdc-9 & btsid = 2100bdec16069784779974377e9ab2 & ws_ab_201_test0, searchweb3) . An example on ender3 but you can mount it on any printer ... including the prusa mini :-) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QnrH2Sk7y40.html

@@ultrabeamitaly1 that linked extruder is nowhere close to as good as a bondtech or prusa extruder. Why do you think it's better? It has much worse filament path and doesn't have a 3:1 gear ratio like the bondtech and prusa extruders have.

@@raider1284 I refer only to the mechanical system drag , prusa better ??? do not joke, in the prusa extruder the filament is squeezed between a knurled pulley and a (flat) bearing without a groove :-( very bad mechanical solution to drag a plastic wire, why don't you see this ? In the extruder that I have indicated, the yarn passes between two knurled grooves both connected to the motor, this is a mechanically superior drag condition, about 3.1 ratio for me insignificant, my printers have extruders with 1.1 ratio and works fine About the extruder path is straight, so no problem :-)
