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

Upgraded my cr-10S with this and the quality of the prints have vastly improved. Very well made and clear instructions

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!

Micro Swiss NG™ Direct Drive Extruder is not cheap but when you consider that it does what it says it does and never lets you down it is worth every penny.There are many things that can go wrong with a 3d printer. Removing one of the major headaches, hotend troubles, is a big thing. I have tried various extruders but none was trouble-free.This is fit and forget. I have used mine for the most challenging filaments, PETG and TPU and the extruder pushed them through without any problems. No clogging and no jamming as long as you adjust the tension arm correctly. Micro Swiss customer support is always there and is very helpful. "So if this extruder is so good why did you contact customer support?" When I first bought this I was having problems feeding the filament into it. Through support, I found I was not letting the extruder do the work, all I had to do was straighten out the first few centimetres of the filament and push it through the Bowden tube until it touched the gears and then via the printer's control panel feed the filament through. Easy Peasy. I don't often give 5 stars so believe me when I say this machine deserves it.

A partir d'un certain moment, quand on imprime beaucoup sur l'Ender 3V2, on peut avoir envie de passer sur direct drive pour un certain nombre de raisons, qui sont la plupart du temps valables.Le souci majeur, c'est le poids de l'ensemble en direct drive, ce qui oblige certains utilisateurs a rajouter un second moteur Z. Micro Swiss a fait un système bien pensé, et au global très léger. Suffisamment pour qu'il n'y ai pas de différence au niveau de l'axe X, a gauche et a droite lors du déplacement du système. Donc pour moi on évite des dépenses qui ne sont pas nécessaires, et ceci dès le début.Il y a tout ce qu'il faut dans la boite ( support de ventilo, pièces la plupart du temps déjà assemblées ) il faudra néanmoins récupérer l’élément chauffant, et le capteur de température, les 3 rouleaux sur l'ancien assemblage. Je trouve que c'est une bonne idée dans le sens où on les possède déjà. Le moteur est bien fourni.Le manuel de montage est dispo sur leur site, mais globalement c'est rapide a monter, et il y a les E-steps ( 400, mais a affiner ), ainsi que les variables concernant l'emplacement du BL/CR Touch a modifier, il suffit de reprendre ceux d'origine. Modifier les paramètres concernant la rétraction sous Cura aussi. Affiner ses réglages avec des tours de températures, et de rétraction ( MS recommande 1mm ).Je pense que c'est le type de système a acquérir après pas mal de mois passé a jouer sur les réglages en Bowden, tester plusieurs firmware etcLa buse et l'ensemble de ce qui est fourni est d'excellente qualité... le système est fiable, et avec le recul que j'ai dessus, il est excellent.C'est un peu a mon sens l'upgrade ultime sur une base qui fonctionne très bien en Bowden, mais là on est vraiment un cran au dessus, niveau perfs/résultats etc

Habe den MicroSwiss NG geholt um weiches TPU82A zu drucken. Man sollte sich bewusst sein das die Extruder Fördergeschwindigkeit für weiches TPU langsam sein sollte weil das Hotend sonst mit dem schmelzen nicht nachkommt. (evtl werde ich einen Volcano anpassen um zu schauen wie schnell ich dann drucken kann.)Zudem sollte die Kühlung etwas verbessert werden - 1 Lüfter reicht nicht, ich habe 3 gestapelt.Jetzt schafft der Drucker spielend TPU mit 35mm/s, bis jetzt ist es der beste Extruder Kopf den ich kenne.
