Description

This tensioner helps to maintain a good synchronisation between the two lead screws. That keeps the X gantry parallel to the bed during a print but also and especially between prints when the stepper motors are off. So the layers stay parallel as well.

With this tensioner, I have got much more consistent layer heights and the walls quality was improved especially when using thin layer heights.

Compatible Printers

This is a non-exhaustive list of compatible printers. This list was mostly done by inspecting the printers on pictures. So there may be some errors.

Don't hesitate to post comments and makes for me to be able to update this list, thanks ;)

Installation

Slide the tensioner from the center of the extrusion profil to the right (or left) to adjust the tension.

You can choose to place 1 or 2 tensioners depending on how much the belt needs to be tensioned.

NOTE - this tensioner could interfere with the extruder footprint.

I recommend you to test your max Z travel and to adjust your slicer profil and/or your firmware accordingly.
