20mm OpenBeam

[johnkraczek]

I found some open beam for a good price and i want to make the Kossel. BUT i found 20mm Openbeam.

What would it take to update the pieces to be more parametric like it says in the configuration file? i am happy to fork and work on it but im not 100% sure what all needs to happen as i am not yet very intimate with all of the code for this project. i am pretty good a openScad and would love to contribute. - how would we go about making this more parametric?

15mm/20mm/25mm/etc any size - it should be parametric, imho

Can someone explain exactly what 'more parametric' means in this instance.
10 (MakerBeam), 15 (OpenBeam), 20 (V-Slot), 40 (MakerSlide + V-Slot). Using these standard sizes allows for easier sourcing of parts . The Rostock MAX uses 25mm (not an open source profile), trying to adapt / enhance it proved difficult.

// OpenBeam or Misumi. Currently only 15x15 mm, but there is a plan
// to make models more parametric and allow 20x20 mm in the future.
extrusion = 20;

Can i set extrusion to 30? or 40? Frame_top.scad, for example, look as garbage when 25 or more.

@bobnet parametric means using a parameter to the aluminum extrusion profile size (10, 15, 20, etc) and the parts will re-size accordingly to accommodate the change.
