So, can you post up a video of your printer pushing 30mm^3/s with a decent surface finish?
Even with thick 0.15mm layers, 250mm/s printing is only 15mm^3/s. I was able to hit that with perfectly fine extrusion, but circular perimeters were terrible. It looked like a control issue; uneven jerky speeds. When using slower perimeters on the new Cura, it underextrudes the infill.
Maybe we just print with different expectations.
No, precisely because I can't melt 30mm³/sec. That's two or three times what the standard print head/extruder can extrude.
Having a large nozzle makes it easier to sustain in the 15-25mm³/s range, but that's about as far as I can reliably go with PLA. With a 0.65mm nozzle, and 0.2mm layer height, that's about 170mm/s linear speed. I don't have to even get close to 250mm/s to start bumping into the limits.
Which was the point I was making in the first place.

How do you like the PHA overall? Consistent extrusion and good bonding?
