Software suggestions and requests

The simpler method is to use a pump with two tracks whose rollers are 90 out of phase and then follow that with a permanently trapped bubble. Imma draw a shitty paint thing to illustrate.

Amoose136,
Thanks for your suggestion and drawing. I think the alternating rollers would reduce the error by half, but the accumulator only smooths the dynamic flow. Once the pump stops, if a roller is engaged in releasing a pinch (between 100% and 0% pinched), the pressure would equalize and any error would be transferred to the print tank. However, it is all probably moot, based on my back-of-the-napkin analysis. And, if we can hack the slicing software, we can stop the pump at regular intervals between pinches and eliminate the problem entirely. See my reply to CescoAiel.
