STEP 30 Wrapping the cable bundle
Before we proceed further, we need
to twist the textile sleeve. This will
prevent the cables inside to slip out
during the printing.
Using your fingers gently twist the
sleeve (not the cables) and create
several wraps.
Twisting the sleeve will effectively
shorten its length. In the next steps
you might need to twist the sleeve
slightly back to prolong it.
STEP 31 Connecting the extruder cable bundle
Separate the nylon filament slightly from the rest of the cables. No need to unwrap
the sleeve.
Slide the NYLON filament in the hole.
If the nylon is hidden inside the textile sleeve, use the technique in the previous
step to reach it.
Make sure the filament isn't pushing into the X-axis motor cable, which would
indicate it is too long and you need to slightly unwrap the sleeve and push the
filament back.
Slide the sleeve in the holder at least 3/4 of the holder's height.
Again, ensure the filament isn't pushing the motor cables and if needed slightly
unwrap the sleeve and push the filament up.
Use the Extruder-cable-clip and two M3x10 screws to fix the cable bundle in place
