Are people using volumetric units and firmware retraction?


I saw volumetric units mentioned in Triffid’s calibration guide, so as per the title are people doing this?

I also like the idea of adjusting retraction on the fly - I am going to look into it.


For what it is worth, I gave this a quick go this morning, using the RepRap (Volumetric) profile in Cura. All worked very smoothly - I can tweak retraction on the fly - which is awesome, and the extrusion looked about perfect - with no other changes needed. I had to cancel after about 15 layers as I realized I forgot to add a support, so the part would have failed, but at first glance I like what I saw.
