STEP 17 Assembling the IR-sensor cable
Take the IR-sensor cable and locate the end with the smaller connector.
Place cable in the X-carriage, use the small printed overhangs to keep the cable
inside.
The distance between the connector and the X-carriage should be around 15 mm
(0.6 inch). We will adjust it later.
Guide the cable through the slot,
remember this path , we will use it for other
cables as well.
STEP 18 Assembling the X-carriage
Following cable management is
CRUCIAL for the extruder TO
WORK PROPERLY! Read the
instructions carefully.
Start by making a small loop just
below the extruder motor. Leave a
slack about 2-3 cm (0.8 - 1.2 inch).
This is comes handy for easier
disassembly in the future.
Then guide the cable in the
"channel" all the way to the back.
Slightly bend the cable down to
form it around the edge.
Also, prepare X-carriage, both
M3x10 screws (if you haven't used
them already) and the longest Allen
key with the ball-end, you will need
it.
