MicroSwiss Direct Drive CR10-V2 Conversion by Siganberg

Last crawled date: 3 years, 5 months ago

Update: Version 2 is thicker and I use PLA+ to print it to get more rigid especially on the area where BL Touch is mounted.
Custom Mount of MicroSwiss Direct Drive Extruder. The housing design leverage the existing front cover since it already has a nice duct air cooler and to achieve close to original looks of CR-10 V2.
Materials needed.
Printed in PETG material with .2mm resolution.
You need one M3x8mm screw to mount the backing housing to the plate.
You also need to replace the X-axis timing belt. The existing one will be shorter for the MicroSwiss mount. Here's the link for the timing belt: https://amzn.to/3fiKZpd
Instructions on how to install:
Assemble first the heater block. These include the extruder head and heater and sensor.
Alight the heater block to the new back housing. Slide the PTFE tube from the top all the way through the heater block.
Install the back housing by sliding the top side of the PTFE tube to the MicroSwiss plate, align it with the hole, and then push up.
Use the 2 screws for the heater block to mount it to the backplate.
Use an additional 1 M3x8mm screw to secure the back housing. This screw and the heating black pressing the back housing is enough to hold it in place.
Route the heater and sensor wire to the channel of the back housing.
Put the front housing and screw the 2 fans. This will join and hole the housing completely.
Mount the BL-Touch (if you have one)
Follow the rest of the MicroSwiss instruction to connect the rest of the wires.
For Creality firmware adjustment, we need to adjust the extruder step and the BL-Touch.
For me, these are the adjustment I did.
Extruder Step: 138.00
BL Touch Offset: X45.00 Y-13.00 Z-2.70 - Mostly you need to figure your own Z offset. You can use the same X and Y offset as mine.
Note: For Printing TPU or flexible material, I highly suggest not to use the Filament guide and just go straight to the direct drive extruder as PTFE create a lot of friction on flexible materials.
The command I use adjusting using octopi Terminal:
M851 Z-2.70 //-- Adjust Z BL-Touch Offset
M92 E138 //-- Adjust Extruder Step
G28 //-- Home Extruder
G29 //-- Perform BL Touch Calibration
M500 //-- Save
M501 //-- Restore/Retrieve current Settings
