Compression Ratio #1

I just realized this should probably have gone into the plugin repo, sorry about that. I noticed the compression ratio display actually showing space savings. See this wiki for the formal definition.

I'm running some tests right now, printing a file with a mix of g0/g1/g2 and g3. So far so good.

Also, fyi, so far Octolapse is working well with MeatPacker, so that's great! I figured it would, but confirmation is always good.

I tried pushing the speed of the print as far as it could go, but travel moves skipped. I'll try to craft a test to determine the max gcode send rate with and without meatpacker somehow, probably using some test I developed for arcwelder. It is not an exact science, but I think I can get a general idea.

Have you taken a look at buffer buddy? there was a firmware modification made for that plugin that can query the printer to check for planner starvation. I think that would be very useful to analyze the effects of MeatPacker.

Here is an article about the M576 Gcode from chen.do for planner analysis, which you may find useful (or you may already know about).

Thanks for the information and clarification on Space Savings vs Compression Ratio, I got that mixed up!

I will look more deeply into buffer monitoring as well, interesting link!
