s curve control board

[Bill_O]

I need a control board that does s curves.
I am running 2 x axis servos. (Currently get same step and direction input), 1 y axis servo, 1 z axis servo, 1 rotary atc servo and spindle speed control.
Need some suggestions from anyone.

Thanks, Bill

Why???

I have done some machine building and S-Curve accel is not always better.

the gantry is almost 3000lbs
the head is 700lbs
it needs the s curve moves

Bill I think you are going to have to find a "controller" that does Scurve trajectory from the planner (Mach currently  does not).

A lot of work was done on the acceleration curve and slope in the excellent Tempest Trajectory planner which now appears to be an abandoned project. Shame really because it was much faster at 2.5D work and allowed higher accelerations without stall on my router.

From reading other threads I think Bill_O is on to this already.
