Mm/sec^2 is the unit you are looking for.

To each their own, but I consider none of that to be acceptable print quality.

I have no desire to do work for you in order for you to perform a "comparative engineering quality control analysis". I don't print at those sizes or layer heights. If parts that my printer made looked like that, I would not be claiming that those speeds were valid. Makes zero difference to me what your design is, I just look at the output. Your opinion is different, it's your machine and you make the output to whatever standards you want, do whatever you like.

Why not just do a search for Voronoi LED Egg tealight shade images
and use those for comparison.

Is the Voronoi LED Egg tealight shade a good test?

I don't know what is a good test for 0.6mm nozzle and 5000 mm/sec speed?

looks good. congrats on getting this to work. how well does it maintain print calibration when you fold it move it and set it back up to print?

here's a photo of the proof-of-concept (1-in-2 scale) which took only a couple of hours to mock up, and, importantly, allowed things to be "moved" so that they could be verified as having the right amount of travel and clearance:

A concern I have with that photo is that the belts are only going round the motor pulleys for about 90 degrees. Is that really enough, especially if you will be using 16-tooth pulleys? I would have aimed for 180 degrees by moving the idler pulleys.

Or add a few more idlers - there's only 19 plus 2 motor pulleys.

I have lost track of pre-existing constraints
Maybe like this --- motors at corners
motors up, shafts pointing down
Use of a spring tension idler near motor,
gives you good contact arc on drive pulley

I am crazy for continuing this insanity!!!!!

My sketch was not to scale at all, and the size of all components
is arbitrary.

Your requirements / constraints way beyond insanity or practicality.

Are you building 10 -15 coreXY mechanisms to swap out on top?

7 days to finish? I think it has been 7 months
