Micro Swiss NG™ Direct Drive Extruder for Creality CR-10 / Ender 3 Printers (Drop in Upgrade, No modifican Required)

Night and day difference in terms of print quality and reliable printing, compared to the stock hotend, particularly for PETG. It is a beautiful piece of engineering.Since their instructions are more Marlin based, here is my Klipper installation experience:* Installed on an Ender 3 Pro / Klipper setup. Installation was straightforward. BTW - I hated messing with Marlin, and I am a software engineer, but find working with Klipper so easy.* Performed "e-step" calibration. They suggest starting with 8 for rotation_distance, I ended up at 7.8.[extruder]rotation_distance: 7.8 #microswiss* Adjusted the XY offset for BLTouch[bltouch]x_offset: -40y_offset: -10* Performed hot end PID calibration - no problems. I think because the Microswiss shroud better directs the fan, the control loop seems tighter than before.PID_CALIBRATE HEATER=extruder TARGET=245...once done, save...SAVE_CONFIG* Changed slicer to 1mm retraction. Haven't tried retraction / stringing tests yet, but no problems with 1mm.* Adjusted Z offsetFirst print benchy came back *perfectly* in PETG. Using stock equipment in the Ender3 pro, PETG was hit or miss.Some observations:* They don't provide a bracket for the BL/CR Touch, so print your own before you tear down your current setup. It should probably be in PETG or ABS for sufficient strength and heat resistance, which is a catch-22 because that is the reason most people switch to an all metal hot end. I would prefer if they included a metal bracket.* Because they reuse many components (both fans, heater element, thermistor), it makes the process much easier, since you aren't rewiring the control board. That being said, be very careful with the thermistor, they are super easy to break.* You might find loading filament a bit difficult. It will operate differently from the stock Bowden setup.Start the extruder turning first, then feed the filament. The gears will grab the filament as they are moving. I have also heard it is helpful to cut the filament end at 45 degrees.Overall, the best upgrade I could imagine. My congratulations to Microswiss on an excellent product!

Simple installation with all the required hardware except for a bracket for the CR touch. I printed a CR touch mount prior to installation using the STL files from the Micro Swiss website. Unlike the Creality Direct Drive I did not need to change wiring on the motherboard. Changed the E steps and retraction values and had a good print first time out. Prints using TPU now work great. Did get the kit on black Friday, so the pricing made this a no brainer. So far the best mods to my Ender 3 V2 have been the CR touch, this kit, and the PEI build plate.

I have been rebuilding my Ender 3 for a couple of years now so I decided to go ahead and get "the ultimate upgrade" and pull the trigger on the Microswiss NG Direct Drive Extruder. In all honesty, it was a breeze to install, however, the filament keeps getting stuck between the heat brake and the heat block/nozzle. It is a nightmare! I can print for 4 hours very smoothly and out of the sudden, this thing gets clogged. I have tried too many options (bed leveling, retraction settings, temperature, etc) and wasted too many hours printing and trying to get this figured out. Definitely not worth it.

An excellent upgrade for my classic CR-10. I can print way faster now! It fit well and was not too tough to install. I thought the included directions were very clear.

The media could not be loaded. I replaced my stock extruder on my VoxLab Aquila printer with the Microswiss NG direct drive. I'm new at all of this 3D printing world, so there are a few frustrations involved in getting started. Well, I finally said screw it and paid for the Microswiss NG and it was delivered in less than 2 days. We couldn't wait to change out the unit and install this incredible piece of machinery. Like I said, I'm new but I am mechanical and can put stuff together. It wasn't hard to do but I did have to play around with things but all in all it wasn't all that bad. It took me a minute to get it set up with all the firmware and start off with my first print. Installing the filament was super tricky and we almost gave up and sent it back. We thought it was a defect or something like that. So I watched the provided videos and learned that a sharp edge cut on the filament was needed. A little finesse and all was well. I set up my z offset and began to print. I had 3 fails on a skull print with my old extruder and was worried that a fail might be imminent. Not a chance in hell. The Microswiss NG smoked right thru the print and it came out amazing. The shiniest and most glossy print that I have ever seen. You can hardly see the lines within the print. So I only have it a 4 star because no one is perfect but I will highly recommend that you dig into your pocket and spend the $100 plus bucks for the extruder and stop wasting time with fighting the most frustrating fight of your life and begin to print with confidence. Thank you Microswiss for this unit. This is completely just my own opinion.

The print head is excellent! However, 400 e-steps is a good place to start. On my Tronxy XY3, I had to set it to 600. I did this by using gcode since I did not have access to the firmware. Where I later learned it is available on Github.Customer service responded to my emails quickly and kindly even when I was getting frustrated on setup. I work with RPET and I was having what I thought was some odd purge issue. I threw my hands up and decided to hit print. The print was the best print I have seen yet. Take the time and make sure you do your printer maintenance.

A bit on the pricey side considering the machines it's designed for, but you certainly get what you pay for and I'm kinda attached to my little workhorse ender 3 lol. It's very easy to install in about an hour and the instructions are clear. Looks and feels very well made, original hardware feels like a toy by comparison. I have about 50 hours of use on it so far and it's working great for me.
