> 3 dayThe nozzle that came with my kit was just a brass nozzle and not a hardened one. Just printing PETG and its already having major issues.

> 3 dayInstalled this for my modded Ender 3 Pro. The extruder itself is fine but the hotend sucks. It has no supporting screws so it is free roaming, and also leaks filament constantly. For something that is nearly $100 Id expect much better. Update: Microswiss offered to send a replacement hotend and was very helpful when I contacted them. Everything works great!

> 3 dayI was able to press my gear off with a drill press and some creativity with supports under the gear and a punch in the chuck, I also dremeled a flat spot on the shaft to accept the grub screw. Also does anyone know what the exact filament color/brand/and material of the red printed spacer supplied is? Thanks.

> 3 dayDon’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.

> 3 dayIt is great if your filament is getting jammed and /or your extruder is dripping

> 3 dayUsing ender 3 this direct drive/hotend combo made my prints great again when my stock head seemed like it had constant issues. The stock setup brass gear stripped out and hot end clogged non stop. This new Microswiss is a game changer for me.

> 3 dayI ordered this upgrade for my CR-10 after I had some sort of failure of the factory extrusion head that caused my heating block, heat sink, and fans to become a giant, fist sized ball of plastic. I had been wanting to go to direct drive for a while, based on experience with some other printers with it, and this failure was the push I needed to order the Micro-Swiss kit. The Micro-Swiss kit is exceptionally well made, the base bracket is machined aluminum, and it all fit together very easily following the video that is linked from their website. They include a small business card with a QR code that takes you to the video, which is nice. I did have one small issue, the countersink for the shoulder screw for the lever arm wasn’t quite deep enough, and as a result, the screw would pinch the lever arm tight against the base bracket when tightened down, rather than the lever arm floating on the screw shoulder. I fixed that with some very light filing of the back side of the lever arm pivot boss to effectively make it thinner, it took only a few passes of a fine tooth file to get it to fit as intended, so, I consider this within the regular fit and finish of installing something like this, but could be fixed at the factory by cutting the screw countersink jsut a hair deeper. I calibrated the steps on my CR-10 following a few videos off YouTube, and I settled on 139.25 steps per mm as optimal. One other thing that must be done is offsetting the X and Y home, as the true, limit switch driven home now hangs off the build plate a bit. I am getting beautiful extrusion with this direct drive kit; the dual mesh drive rollers really bite hard into the filament, and the heat brake works amazing. You can heat the head up, unload the filament drive lever, and pull the filament back out of the hot end no problem, and the end that comes out looks like it’s been clipped by a pair of scissors! No swelling of the end in the brake like some hot ends, no stringy tail, just a clean square end. The first time I pulled the filament back when doing the step calibration I thought it broke off in the extruder, but, 3 more tails exactly the same has me convinced The heat brake just works that good! I’m running a .8mm nozzle in my CR-10 at 70mm/s speed and this extruder kit has absolutely no issue keeping up!

> 3 dayPrint quality now has jumped up a lot, not sure if because over all quality better parts or because the filament doesnt have to retract as much anymore or both. I really want to buy another one for my second ender 3. Would recommend. Takes some time setting it up with new esteps and changing your x home, but well worth it.
