How to install the Micro Swiss Direct Drive Extruder on a CR10S Pro V2 with a BL Touch.

Installing Micro Swiss Direct Drive Extruder to a CR-10S Pro

In this video, the presenter goes over the steps required to install the Micro Swiss Direct Drive Extruder to a CR-10S Pro. The extruder kit is specifically designed for the CR-10 and Ender 3 models but can be adapted for other models with some preparation.

Challenges of Upgrading

• The upgrade adds weight to the gantry, which can cause calibration issues.

• The BL touch will need recalibration as it will be in a different position than before.

• The bracket provided by Micro Swiss was not designed specifically for the CR-10S Pro V2 model, so modifications are necessary.

What's in the Box?

• Instruction video link, sticker, extension cable for extruder motor, screws and hardware for tensioner, mounting bolts for wheels, Capricorn Bowden tube.

• 3D printed guide and zip ties.

• Bracket that needs modification to fit properly on CR-10S Pro V2 model.

Disassembling Printer

• Remove fan shroud cover and fans from inside and outside parts cooling fan.

• Original bracket is wider on one side than Micro Swiss bracket. Hot end is offset more to one side. Original shroud won't fit. Bl touch won't fit in original position as none of these holes line up with any of these places.

Creating a 3D Part with Recessed Base

In this section, the speaker explains how he created a 3D part in OnShape and added a recessed base to allow for the bracket that holds the fan for the heat sink. He also mentions that he will include all files free of charge.

Upgrading Ender 3 Bracket

• The speaker provides an STL file for those interested in upgrading their Ender 3 bracket.

• The stock fan uses two-millimeter bolts to hold it down, and you have to drill and tap the Ender 3 bracket with a three-millimeter thread pitch to use the stock fan and bolts that came with CR-10S Pro.

• The speaker shows his Micro Swiss all-metal hot end behind the shroud, which is another upgrade he made.

• He changed the heater element from a 40-watt to a 50-watt heater element, allowing him to run hotter temperatures after doing firmware upgrades.

Assembling Direct Drive Extruder

In this section, the speaker assembles direct drive extruder by removing wheels and transferring parts over.

Removing Wheels

• The first step is releasing tension on the arm so that you can take out the bracket.

• You need to remove bottom wheel before moving belt; otherwise, it will roll around.

• Use thread lock or something on screws if they are stripped.

Transferring Parts Over

• Micro Swiss direct drive extruder brings its own set of screws; therefore, original ones are not used.

• Little wheels bolt on without using any spacer things except concentric one.

Introduction

The speaker introduces the topic of the video and briefly discusses what will be covered.

Speaker Introduces Topic

• The speaker introduces the topic of the video.

Discussion on 3D Printing Filament

The speaker discusses their experience with 3D printing filament and how they have improved their printing process.

Improvement in Filament Exclusion

• The speaker is happy with their current filament exclusion.

• Previously, the filament would come out like toothpaste, but now it comes out like a syringe.

Positive Feedback on New Equipment

• The speaker is very pleased with their new equipment.

• They prefer their current setup to what Microswiss had recommended.

Modification of G Code for Proper Homing

• It is possible to modify the G code when starting a print to ensure proper homing.

• This modification can be built into one's profile for future use.

Firmware Customization and Limitations

• There is custom firmware available that allows for higher temperature printing, but it disables touch screen functionality.

• A kit from another company may be considered as it provides more functionality and allows for higher temperature printing than currently possible on this machine.

• Currently, there are limits on temperature due to hardware constraints (around 270 degrees).
