Extruder Upgrade Kit for K8200 3D Printer - For use with 1.75mm PLA or ABS filament

Improve the quality of your 3D prints with the Velleman K8203, a direct drive extruder add-on/replacement for the Velleman K8200: 3D Printer Kit. The K8203 extrusion upgrade kit replaces the standard 0.5mm nozzle with a 0.35mm nozzle, which allows for 1.75mm PLA or ABS filament prints versus the standard 3.00mm filament prints. The upgrade doubles the resolution of your prints from 200 microns (0.2mm) to 100 microns (0.1mm), the same resolution as our K8400 3D Printer Kit.

Velleman K8203 Extruder Upgrade Print Example

Simply remove the existing extruder, replace it with the K8203 Direct Drive Extruder and watch as your K8200 3D Printer produces some of your smoothest prints yet.

Please note: To benefit fully from the K8203 upgrade, it is recommended that the Z axis is also upgraded using the Velleman K8204: Z Axis Upgrade for K8200 3D Printer.

    This is an excerpt that I posted on the Velleman K8200 forum:

    I thought I’d start with “the Velleman way” as my first replacement extruder. For the cost, I not only upgrade to a more precise extruder, .35mm vs .5mm, I also switch to the more common 1.75mm filament, and switch to gearless direct drive.To me a hallmark of reliability is simplicity.

    The Good:
    I ordered the K8203 from VellemanUSA and it arrived quickly. The kit is very nicely packaged, and the front of the box has the web address for the installation procedures, along with a QR code in case you want to access the instructions that way. The web instructions are quite good, with only a few exceptions. The pictures are very clear. The quality of the parts is very good. The only thing that needed adjustment was lightly filing the inside of the filament pulley to get it to slide on to the stepper motor.

    The Challenging:
    I built mine with the stepper motor to the left, like the instructions show. When reflashing the firmware I had to modify Configuration.h to reverse the direction of travel.

    CODE as published:
    #define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false
    CODE fixed:
    #define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

    Don’t forget, In Repetier Host send GCode M502, then M500 so reset the EEPROM. I would suggest that Velleman issue two firmwares and include in the filename “..Stepper motor mounted LEFT..” or another firmware “..Stepper motor mounted RIGHT..” with the correct changes implemented.

    From my measurements, the new extruder sits 15mm closer to the Z gantry than the original extruder. The new extruder is now farther back on the Y axis. Move your entire upper frame 15mm forwards and the extruder should now be centered on the bed. Velleman needs to add that to the instructions.
