I need help sorting out the flickering from my laser while projecting, I understand that projecting a simple picture with minimal stops help, how do I go about with a picture more complex? Thank you.

... much, much faster (and much more pricey too) galvos and drivers ...

What projector do you have? Most inexpensive projectors have 12k~15k galvos even though most adverts claim 25k. You could pick up some chinese 30k galvos for a decent price that would vastly improve the flickering issue. It helps to know what you have now and also what you're trying to project.
If you're the smartest person in the room, then you're in the wrong room.
Reduce the points or reduce the scan angle.
or use distributed scanning in pangolin beyond it allows multiple projectors to project a single image sharing the load
or get cambridge 6215 about $5000 scan speed about 60k
or ems 8000 $1400-$1500 58k stated
or saturn $2600 i have heard 120k but i cant confirm that i would say 60k np
If I'm not mistaken Cambridge just doesn't sell through Edmund anymore. Now if you mean they're out of the Laser Light Show Business, I'm pretty sure they never developed anything intentionally for laser light shows. There was just some accidental overlap. Cambridge has never been interested in the low end of the market.

Respectfully have to just disagree a little, at least for ten years or so.
In the ILDA Conferences of the late 1990s, Early 2000s , Cambridge Sales staff came to party with us, judge contests with/for us, brought engineers to teach us, listened to us, and developed ceramic bearings for us. (H models). Then they changed their broadband dielectric coating to retain red instead of leak it with respect to rotation, for us.. Things were happy for many years. Then they merged with GS, and GS sales took over, changing a lot of policies in the hopes of only selling to really big clients, followed by Novantia buying the whole mess. One Stop laser Shop went out of business and thus bulk sales of scan pairs with amps went to zero for the GSI/Cambridge combo and now they ignore us.
They still make the 6210H / 6215H, but just try to get affordable pricing.
Picture attached tells a cryptic story if you know who their recent sales structure was set up by. That manager was the $arcastic fun police....
I remember the scanner amp engineers pulling me aside for lunch together. Serious Geek chat on scanner amp internals and motorcycles. Plus a open to anyone hands on amplifier calibration / tuning training /diagnostics session that was amazing, complete with oscilloscope and test jig. If you completed the hands on portion of the course you received a service manual / schematics handout. If you completed the course you knew how to bring a 685XX amp up from scratch.
I had a chat with one of their executives at CLEO some time ago and he was sympathetic, but explained they were retaining their hottest, newest stuff for internal use. After I walked up and asked him how he was scanning a glow demo with what looked like 3x3" mirrors.
