Core One INDX Filament Sensor 1-4 and 5-8 backside mount with cable managment

Core One + Gen2 INDX rear mount for the filament sensor with integrated cable management – no loose cables outside the printer.

This rear-mounted bracket is designed to

• provide the shortest possible filament path from the sensor to the toolhead

• allow for flexible filament feed positioning (side, top, rear, etc.)

• have no free cables outside the printer

• provide protected cable routing to the sensor

• be compatible with most filament sensor modules

The sensor holder consists of

• a base unit with cable managment

• adapter units to adjust the feed position to the PTFE tube inlets

• a cable protection cover for the sensor cable going to the xBuddy Extension board

Printing recommendation:

• 0.4 nozzle

• 0.2mm balanced

• 3 perimeters

• 3d-honeycomb infill or gyroid infill

• support on build plate only, style organic

Mounting instructions:

• Gather the base unit, an adapter, sensor unit 5–8 and a sensor cable

• Have two M3x35 mm screws ready

• Connect the cable to the connector on the sensor board

• Route the other end of the cable through the right-hand cutout (see image below) in the base unit

• Place the adapter between the base and the sensor unit

• Use the slot to route the cable through the adapter (see picture below for orientation)

• Hold the three parts together and fasten them using the M3x35 mm screws

• Do not overtighten the screws, as they thread into the plastic of the sensor unit

• Take the second adapter, sensor unit 1-4 and a sensor cable

• Have two M3x35 mm screws ready

• Push the cable from sensor 5-8 into the bottom recess leading to the other sensor unit

• Route it back on the backside of the base unit and again through the recess on the bottom side

• Route another loop at the backside and back to the bottom recess until three loops are done

• Check if all three loops go beneath the cable clip at the middle of the base

• Take the plug of the cable trough the cutout and plug it into sensor board 1-4

• Take the second cable trough the cutout and plug it into the sensor board 1-4

• Now put the adapter in between the base and the sensor unit 1-4 

• Use the slot to route the cable through the adapter

• The cable from sensor 5-8 should not be tense on the plug, otherwise reposition the loops

• Hold the parts together and fasten them using the M3x35 mm screws, do not overtighten

• Now root the second cable through the bottom recess to the right side of the base

• Have two M3x8mm screws and two M3n nuts ready

• Put the nuts in the recesses of the base unit (on the sloping back)

• Hold the assembly on the printer top back frame and use the M3x8 screws to fix it there

• Remove the rivets on the right transparent side panel, remove the panel

• Remove the right top frame (4 srews) and put the cable throug the opening at the top right back corner, remount the right top frame

• Remove the cable cover on the backside (two screws on the back through the front door)

Push the cable through on of the openings at the right back corner, see picture (from prusa manual) below

• Open the xBuddy cover on the backside and connect the sensor cable to the top right connector with the label EXT 

• Remount the back cover and the cable cover

• Remount the right side panel with the rivets

• Mount the cable cover on the right rear side, first place the shift plate into position the put the cover in the recess of the base unit (mounted before) where the cable comes out and push it down, do not pinch the cable

• Screw the cover down with a M3x12rT screw (a M3x12 screw will it do also)

Almost done, yet one important info to carry out your next step is missing:

The PTFE tube lenght from the sensors to the toolheads should be 49.2 cm !
