Micro Swiss Direct Drive Extruder for Creality CR-10 / Ender 3 Printers

be very very careful cleaning this hotend! I purchased it less than 3 months ago and have stripped the grub screws. it is junk now. cant find anything about a warranty on amazon. Im going to look at the MS website. probably doesnt cover my issue though

Excelente inversión es seguir el manual para instalar y funciona perfecta

I absolutely love this thing! It has made my ender 3 reliable! I can actually trust my printer again. And the prints come out beautiful.

After getting my printer setup properly and tuning the profile settings, I was able to get some great results from this product. Well worth the price for the direct drive chassis with the all-metal hotend included. If I can get a lighter stepper motor for the extruder I could push this setup even faster.

thanks

Don’t use flexible PLA with this, not matter how many adjustments I made the extruder would allow the Filament to escape and make a larger mess.

Listed as a bolt on, not a bolt on. Now Im going to have to pay someone to print me a EZABL mount for it.

Solid, worth the money.

I bought this hot end kit to upgrade an old Geeetech A30 printer I have that was well used and abused. The quality of the parts in this kit is top notch! Very high quality machining on all of the parts in the kit. When properly installed and calibrated (!!!) this kit will produce outstanding printing work! Zero clogs or other issues in several very large prints that I have done lasting well over 100 hours each!! Being able to reliably run an entire roll of filament without issues is just fantastic! I couldnt be happier with my purchase. Just to be clear this item was purchased with my own funds and I was not given anything for this review, Im just a happy customer. If you want to take your 3D printer hot end to the next level this kit could be just what you need.

Overall, a huge step up over the bowden if you want to check out hotter or flexible plastics, or just want to try moving away from the bowden setup. Installation is easy, but be sure to read the instructions carefully. A lot of people go on the message forums asking why their new extruder isnt working because they didnt read the part on the new gear ratio rate. Its all listed in the instructions on how to change that. :) A couple of things.. The use of a small section of bowden, on two of mine didnt quite line up properly. As such, feeding the filament through and past the gears resulted in the filament sitting just a tiny bit to the right of the capricorn tube that leads to the hot end, needing help to be pushed over and in. Cutting the plastic like a needle edge helps sometimes to steer it in, but for some reason its set just slightly too far to the right.. If the tube was ballooned out just a tiny amount there rather than cut in the cross pattern they chose, it would fix everything. Ive had some brittle plastic break there several times, and its literally because theres a slight mis-alignment. Shouldnt be a problem with most, but, when things dont line up flawlessly, theres a fault zone for everything, even healthy plastics.. Flexibles too will spool out at a lower speed than they need to at that point if it isnt aligned correctly. Perhaps making it slightly adjustable there would be more effective than trying to mill everything to perfection? If I could move that tube over to the right 1mm, it would be perfect. As it is, Im going to replace the length of tubing and flare out the end to aid it in alignment. The bowden above the extruder that feeds in filament is held in place with a small E-Clip. With the continuous back and forth jostling of retraction, it continually pushes out and ultimately onto the build plate. Ive heard from several other owners who simply stopped using it, but some kind of more traditional holding method for the bowden should be here when this doesnt work. Toothed couplers work well on regular setups, so I dont know why they arent used here. Ultimately, without it, the bowden can be pulled out, which isnt the worst thing when it comes to simplifying filament changes, especially when the plastic doesnt quite line up as mentioned above. You can assemble a line of filament, then push the tube in to secure it for the print after its all secured. Retraction is set so low on direct drives that it wont come out through regular printing, but its a little sloppy. I heard that they were working on a more effective clip and would send me one, but they never did. I feel a rounded edged surround for the tube there made from nylon would make a much better overall solution to using a bowden that were trying to remove anyway to continue to guide the plastic to the gears. That way its gone, and like most direct drives, plastic can feed straight in without hitting a sharp metal edge. What with the stepper being mounted onto the bracket, it is heavy, and you may need to slow down your print or suffer some noise in your prints. Fix the E-Clip slipping and bowden alignment/add actual couplers overall, and this would be a 5 star item. The feeding accuracy and ease of feed to the bowden after the gearing is by far the most important issue to fix. All in all though, I like it. Im not going to swap back.
