This tool has a scale of 100 mm to calculate the steps of the extruder with the ejection of 100mm of filament.
The part that is fixed to the aluminum profile can remain installed there.
The part that measures can be put on and taken off when necessary.
The PTFE tube can be glued with cyanoacrylate and must be located right at mm 0 and pass mm 10. This way you can make a mark on the filament right at the entrance and see how it moves inside.
It is advisable to use a white filament. Then perform the appropriate mathematical operation to correctly calibrate the motor steps.
The author remixed this model.
He usado estos dos modelos. Los he modificado y unificado para conseguir mi objetivo, medir fácilmente la extrusión de 100mm de filamento para poder calcular la masa del motor del extrusor.
