Bob, you sure know a lot. |
No I don't. The older I get the more I realize how little I know.
While I've done a fair amount of motion control work I've never used Mach so I know nothing about how the parameters in Mach are handled.
When I design a machine I size the motors, amps, screws, etc. for specific performance requirements. Once it is built I write a series of programs to "stress" the machine within these limits. I attach accelerometers to each axis and monitor the machines reactions. Accuracy and repeatability are measured with LVDTs, lasers and ballbars. Lots of fancy equipment and out of the range of the normal DIY.
This is really the equivalent of Mach's recommendations to use the sound and feel of the machines response.
Write some programs testing high and low speeds, long smooth moves and lots of short quick moves. Tweak a setting and look (and listen) for changes.
Setup an indicator and make sure the machine returns to the same spot it started from.
I'm sure there are lots of users here that can give you better info on the settings in Mach than I can.
