Description

MAJ 03/25/2018 :
Addition of motor and built-in centerings in the design.
Thickening of the structure and refining of the semi-flex part.
Increase of the semi-flex surface in compensation.

A more accomplished version of the low cost dampers found on the net.
I adjusted the stiffness of the silent-block to be able to normally tension the Y-axis belt without sacrificing the geometry of the motor / return roller assembly.

you can compare the difference on the enforcement of the geometry in the picture above.

I adapted the dimensions so as not to damage the damper when tightening because of thin walls.

PET EPR is perfect for this kind of technical parts, it is indeed very resistant.

P.S. : If my English seems bad, thank you to address your complaints to Google Trad ';) And, I know, I draw like a kid of 4 years!

Materials and methods

You can adjust the hardness of the damper by adjusting the density of the filling.
I recommend staying at 100% for damper Y-axis because the length of the belt imposes a high tension, which may cause the sagging of the damper.

I recommend printing at a high enough temperature to optimize adhesion between the two filaments.
I printed these parts to 248 °.

Warning :
For an optimal result you must think about indexing the filament flux on the semi-flex and not on the PET!
In order to guarantee a homogeneous, solid silent block and the good adhesion of the semi-flex on the PET, you must deactivate the cooling when you go from PET to semi-flex. You will restart cooling for the final part of PET printing.

Filaments used:
-Innofil PET EPR (Red)
-Recreus 95A FILAFLEX Medium Flex (Blue)

Remember to include two M600s in your gcode if you do not change your fil in manual mode.
Ex: M600 E-10 L-50 X40 Y40 Z100
The syntax of this command is detailed here:http://marlinfw.org/docs/gcode/M600.html
