Updates
25-10-22
“Idler_6-7_R3” dimensions adapted to the Main Plate R4 with angled Swivel. This update is more angled than the previous design to align the screws horizontally and minimize the screw tread friction in the heatsink.
“Main_Plate_9-10_R4” have tighter tolerance to the Gear and modified filament guiding at exit to the nozzle.
“Idler_1-2_R2” have some minor changes
“Idler_1,2,11_R2B” is optional. it's an alternative design to “Idler_1-2_R2” with a stronger beam between part 1 and 2.
Changed material from PETG to PCCF.
Printing
Printing on MK4S. Material PCCF. Nozzle 0,4 and layer 0,2. I use original presetting’s for Prusament PCCF structural except for part 1-2 where I changed seam position to nearest.
The design requires fine tolerances. Check your x-y belt tension and use dry filament.
Idler assembly
The numbers refer to the pictures. No glue is needed.
Press bogie parts 1&2 together. Place original bearings 3 (693 2RS) into the bogie and press original pins 4 (3x8.5) in place. Fix a nut 5 (M3) in the idler lever 6. Place the bogie assembly between idler lever 6 and 7. Tighten firmly with screw 8 (M3x6). Don’t overtighten the screw! Push the original tubular spacer 9 (13.2x3.8x0.35) into 6 and 7.
Main Plate assembly
The numbers refer to the pictures. No glue is needed.
Press together part 9 and 10. Check that the total height of the filament guide is not exceeding 10 mm (see picture). The two parts will keep together when assembled in the Nextruder.
