This is for CO2 GALVO only.

There’s no single “best” kHz. Lower kHz ⇒ higher pulse energy (crisper, deeper).
Higher kHz ⇒ smoother, lighter. Start with the presets below and nudge based on your material and goal.
These parameters are provided as a "general range" and therefore some user testing and experimentation is required.
Individual materials and preference will determine the final combination of settings for each application.
Thanks for the users that who share their settings!
