I've been asked about some seemingly unintuitive behavior: the max velocity slider is not applied to rotary-only motion. You can try this yourself by running the `axis_9axis.ini` config, setting the max velocity slider to zero, and noting rotary axes still move after e.g. `g0 a180 f40`.
This can't be trivially fixed by applying the max velocity setting to rotary-only motion. Back in 2007, Chris explained [1] (referring to a document still available from NIST [2]) that feed rate in units/minute can be unintuitive for rotary-only motion, since the units are degrees instead of inches or millimeters. Ok, so damned if we do, and damned if we don't; then what are the other options? Axis has a couple of instructive examples: - The rapid override slider reads on a percentage scale, and the same slider does what one would expect, both for linear and rotary-only motion. - The jog speed slider reads in linear units/minute, and when a rotary axis is configured a second slider reading in degrees/minute appears. Right now, I'm leaning toward recommending the max velocity slider be changed to a percentage scale and applied to both, similar to rapid override. I'd love to hear other opinions.
