Micro Swiss Direct Drive Extruder for ExoSlide System

Shipped same day as ordered. Perfect fit good instructions. Great prints.

Works good going to try a pancake motor on it to reduce the weight but it works good so far

I already have MSDD for my Ender 5 then I switched to this one for my Exoslide setup. Everything works great as expected with tight fit.

I love the design, it could be comparable to Hemera if it weren't for the fact that it doesn't have the precision that the filament requires. What is this gigantic problem? The Motor Gear. It only has one thread for one screw (this should have two or one that will hold well). So small and delicate that it does not hold the gear well to the motor. That translates to extrusion problems. No matter how calibrated you have the stepper motor, it will not work properly. The other problem with the same piece is the teeth. Without filament they fit perfectly with each other. With a 1.75 filament it is quite another matter. As much as you press, the separation of the teeth of the gears is very large, that produces the annoying and imprecise ghostling and ringing.

Sirs of Micro Swiss, fix that and sell the spare parts so we can print decently. Since for the price (without Nema 17 which is not included) it is unfortunate that something like this happens. I'm about to return the entire kit. I'm desperate.

We upgrade printers to print better, not worse.

I love the design! It is simple and functional and made of quality materials. The installation was easy except for 1 issue which made me decide for four stars and not 5.

Before with my DIY direct drive and cooling mods I had a big weight hanging in front of the gantry. During printing and direction change you saw it moving up en down which came back in the prints. With this well-thought solution the E-stepper motor (weight) is central above the gantry and the whole construction is much more stable and rigid. Also the double geared extruder wheels seem to do there work very well. My first small prints look very good (even though I forgot to run the gcode with the e-step adjustment). I am looking forward to increase the print speed and see where the "ringing" begins.
BTW experiments with several part cooling solutions also made me decide to now change to a much simpler/smaller/lighter -almost standard- cooling solution that allows me to do 65degree overhang w/o support. So this also helped with lowering the forward weight.

The one issue I had concerns the bowden tube retaining clip. During first two prints the capricorn bowden tube was pulled through the retaining clip and in to the gear wheels. I have now sharpened the ends of the retaining clip with a file and hope that this is a good enough solution to hold the tube in place. It did the next print so I am hopeful.

Anyway, overall I am very happy with this excellent part :)

cheers
