    I was minded to say something similar about the bench.

    All this discusion of machines jerking around reminded me (as I briefly mentioned above) of the so-called "s-curve" trajectory planning that uses varying as opposed to fixed acceleration rates. The G2Core software (which will run on an Arduino DUE board) from Synthetos includes this and I had a look at using it a few years ago but didn't persue it. For anyone interested there's an explanation on the G2Core wiki at the address below. Presumably this sort of control is implemented in some of the more expensive software but is not yet used in LinuxCNC, MACH3 or UCCNC as far as I can tell from a search on various forums. UGS will drive G2Core but only via USB I think.

    An optimist says the glass is half full, a pessimist says the glass is half empty, an engineer says you're using the wrong sized glass.
