Micro Swiss Direct Drive Extruder for Linear Rail System

I really like this carriage. Well designed and machined. I was looking to replace my rollers on my Geeetech A30 which is pretty worn out. The original carriage is non-standard, so a complete replacement was needed. I also wanted a direct drive.
Installing the linear rail was easy. The down side was the home sensor didn't work out, but I have a Bigtreetech Mini board that supports sensorless homing and that works pretty well so far. I also had to replace the belt since it was a little too short.
I found a Satsana fan shroud remix I really like on Thingiverse. It uses a 5015 blower which works great! It will print in air for a couple inches without any issues. I did have to cut off the cable support on the one I printed. There are a bunch of remixes that I'll look through now that I can print again.
Note - if you only have 1 printer, make sure you have everything you need before you start!
I have a Creality Spider 3.0 hotend. I had to file out behind the hotend a bit for clearance. Like a mm. Just an FYI. I'm sure a normal one would work fine without modification.
I have a second printer that I'm starting to rebuild and I'm ordering another. Very happy!

I first purchased the Direct Drive extruder kit and all metal hotend for my Ender 3V2. I used it for a number of months with a (few) Satsana fan setups and loved it. Following that, I upgraded to a linear X rail at roughly the same time that MicroSwiss (unbeknownst to me) dropped their extruder kit for linear rails. I purchased this second extruder kit and my device feels "complete" now. I think I've been using it for 1.5-2 years now and would do it all over again if I needed to...or if I bought a new printer. In that time I've been through a few heater blocks (lackadaisical maintenance effort, my fault), a handful of silicone socks (they're wear parts), and a few motor gears (wear parts plus abuse/misuse). I keep a box of spare parts and I'm good to go if a crisis arises. I've successfully printed a variety of plastics, TPU included, without issue. These hotends and extruder kits are somewhat more expensive then the flimflam you could get elsewhere, but they are worth every penny and will last you much longer then the other "less expensive" options would.

I recently installed a direct drive on my longer lk5, so far its been working wonderfully. It took some effort to install because of the way the lk5 gantry was built but I don't regret it.

Great

It's been working great. I've been using the Satsana fand duct. Still need to get better fans on it though because my stock ender 3 fans are making noise now. Unfortunately I can't remove my previous review. The error was on my part, not MicroSwiss.
