Prusa CORE One + Gen2 INDX Bondtech Extruder Cable Sag Prevention

Prusa CORE One+ Gen2 INDX Bondtech Extruder Cable Sag Prevention, a modification for the cable routing from the swingarm to the Bondtech extruder.

Non printable parts needed:

Stainless steel cable tie 900mm x 7.6 mm (sample); 900 mm is the minimum length; any longer version is also fine.

Printing recommendation:

• PETG or other heat resistant filament

• 0.4 Nozzle

• 0.20 mm Balanced

• 100% Infill

• no supports

Mounting instructions: (see pictures below)

• Bend the cable tie around a T6 Torx key at the length of 450 mm

  

• Bend it back so that the end goes into the mounting clamp

• Cut the end 7mm shorter then the clamp side

  

• Push the end into the clamp

• Remove all existing cable fastenings (retain the screw for the next step)

• Using your printed swingarm clamp, slide the cable into the designated position and insert the locking head of the cable tie into the recess behind the cable. The locking head should look out on the right backside of the clamp.

• Place the clamp onto the swingarm at the innermost position and secure it with the screw

• Attach the middle clip to the middle position of the swingarm over the cable tie, insert the cable

• Attach the end clip to the outermost position of the swingarm over the cable tie, insert the cable

• Attach three cable clips on the cable tie with 60mm distance between them, insert the cable

  

• Attach the last cable clip at the end on the cable tie, insert the cable

  

Final step:

Due to the altered load and bending forces of the moving parts, it is recommended that you

• rerun the Phase Stepping calibration

• rerun the Input Shaper calibration
