Comment on Calibrating my E-steps ended up giving me nearly pixel-perfect prints (Creality K1)
AliasVortex@lemmy.world 1 week agoAgreed. Not to burst OPs bubble, but I highly doubt they’re hitting a flow rate that high.
If I had to guess, Orca is capping their extrusion move speeds at whatever speed the filament_max_volumetric_speed of their filament profile is set to. In other words, if the profile is set to 12 (default for Creality Generic PLA) the actual speed is probably something like 150mm/s (flow / (nozzle diameter * layer height), so 12 / (0.4 * 0.2)), regardless of what the speed value is set to.

Yep, you’re exactly right! I forgot that I have the volumetric speed capped at 25 for the Turbo PLA (based that off of random reported values other people used, but didn’t think to try and benchmark it yet). So I’m gonna do that right now! The Overture Matte PLA also prints incredibly cleanly at 300mm/s, so I’m going to benchmark it and the Turbo PLA to see how high this hotend can go. I’ll report back when finished.
