I've tested Max Volumetric Flow Rate and confirmed with secondary tests that Hatchbox ABS prints cleanly on my machine at 32mm/sec^3. So I configured profiles for those and ran some tests. With the default Orca settings for the Voron 2.4 profile, I was only getting 8.4mm/sec^3 max, because apparently that's what a 0.2x0.4mm (layer height x width) at 120mm/sec produces. The various speed settings were holding it back. So I went in and basically doubled all of the non-percent numbers. This did boost the flow to slightly more than double... I saw as high as about 20mm/sec^3. And the print looked good. That felt like a good start.
But the thing is, I have no idea why one number needs to be lower than another, etc. I would like to tune this, ideally so that I can get 32mm/sec^3 flow when the situation allows it, and whatever appropriate slower speeds are needed when the situation calls for that. There are also settings to acceleration and jerk that I am sure are relevant. And It appears that each setting can impact the others. How does one determine these numbers? Is there a calibration test for travel speed while extruding, once volumetric flow capacity is known?
In case it matters, I have a Voron 2.4+Stealthburner with nothing especially relevant to print speed except for a Rapido 2 HF not end. I'd also be curious what settings anyone with a similar build (i.e. no abnormally high amp motors, carbon x-rails or alternate lightweight toolheads) has achieved.
