Additional system information

N/A (not performance related)
issue has been present on both Windows 10, 11, and linux installs.

Printer

Sovol SV06

How to reproduce

open orca slicer
setup your printer (sv06)
have Generic petg, generic petg hf or esun petg selected
go to edit filament to inspect volumetric flow rate.
flow rate is set to 20mm/s
slice project + try printing at speed.

Actual results

open orca slicer
setup you printer
have Generic petg, generic petg hf or esun petg selected
go to edit filament to inspect volumetric flow rate.
flow rate is set to 20mm/s
slice project + try printing at speed.
result: weak and underextruded print
actual result become more noticeable when adjusting the machine movement speed and acceleration to above default

Expected results

open orca slicer
setup you printer
have Generic petg, generic petg hf or esun petg selected
go to edit filament to inspect volumetric flow rate.
flow rate is set to 12mm/s

on default hardware, 20mm/s results in severe under extrusion, weak prints and some failures.

Current Default Volumetric Flow Rate

Reccomended Volumetric Flow Rate change

print results

as well as the print photo, have previously tested on a Volumetric speed test. Max is 12- 13mm/s on a new 0.4mm nozzle. Unsure if this issue may affect other printer profiles. I'd add this myself if i could work out how. (not a coder, new to github)
