Upgrade Dual Gear Ender 3 Extruder 1.75mm 3D Parts Double Pulley Aluminum Mk8 Extruder for, CR6-SE, CR10, CR-10S, CR 10 PRO, Ender 3, Ender 3 Pro

Very hi quality clone, yes clone for those expecting the mircoswiss hotend, but again this is of high quality, fits and works out of the box, once everything including all the little grub screws are hot tightened...don't forget to hot tighten at around 235/240.When pushing in the bowden tube, use a bit of sand paper to help grip it. You'd know that the bowden tube is seated properly once you hear an audible pop, i.e. the end of the bowden tube suction fiting into the heatbreak.For any one who are fussy, the genuine heat break can also be purchased as its likely better quality titanium.My retraction settings is 2.2, with 40/mms speed.Tweak as needed.This product is a direct hotend replacement for the creality ender 3/cr10 variants. So I essentially, added it to the bowden setup, the bowden tube in my case was upgraded to a clone capricorn.

This in principle should be very good. Although - after fitting which was super easy - they hot end which holds the thermistor is only hold in place by a small (very small) hex nut. On my original hot-end there are two spikes which hold it straight. After printing for a few hours there was a rattle and noticed the head had moved / screw had become lose which left the hotend leaking.Avoid this - save yourself. The "copy version" does not save you money in the end .... Lesson learnt.

Why there is not a single metal Dual Gear extruder advertised for the CS6-SE on the market, I'll never know, but this worked fine to repllace the abysmal plastic one that Creality thought was somehow fine to use in a high temperature, high pressure setting (spoiler, the plastic one cracked).This has since worked fine, getting really good grip of the filament.

I had a heat transfer problem, meaning a cold spot which sometimes stopped the filament from melting and then just clogging, the adhesion glue leaked away but both of those were over come by using Computer CPU Heat paste.Its a smaller profile than the factory issue (ender 3 pro) so the BLTouch Zoff set had to be adjusted and z home (m851 setting) had to be adjusted. Handles the Carbon, PTEG, TFE and ABS just fine, tried it with some more controlled settings and was very pleased with the results.Any issues i have had they have dealt with immediatley hence the 5 star, very helpful.

Installed this on a heavily modified Ender 3 when conducting Hot end testing across ranges found on Amazon.This product scored incredibly low, the machining isn't within reasonable limits, general alignment of the bowden tune throughout to the nozzle is out of alignment leading to a poor flow of filament.The nozzle itself on close inspection had a burr across the end which resulted in poor extrusion, once corrected and cleared the nozzle never printed the 1st layer adequately enough to use.

Although not stated in the description, this unit came in a Bigtree Tech box and is indistinguishable from a Microswiss hot end. Excellent machine quality and comes complete with all screws, tools and silicon sock. At this price, its almost a third of the price of a Microswiss. Ran it with ABS, PETG and TPU. Brilliant upgrade!!!!

Total waste of money, between the bit that grips the bowden tubing breaking Inside the heatsinc and filament constantly clogging inside the hotend this thing has been nothing but trouble to work with, the filament seems to snag inside and kink causing a really annoying clog thats hard to remove. I have included photos of what it is doing to the filament.

The media could not be loaded.  Great value for money printing tpu like a dream ,changed nozzle to brass as not a fan of steel nozzles , tpu likes to stick to it . but will use the steal nozzle when im printing abrasive materials 🙂
