how to fast transition from one movement to other ?
« on: August 10, 2013, 03:21:43 PM »
hello dear forum,

I am trying to write a G code interpreter with my own motion control hardware

I can calculate trapezoidal speed profile for the individual axis
however my code waits to finish each speed profile
until the axis is in 10 micron near to the target point

this in turn makes the motion of the axis stop and go , stop and go
( if you think each G code program is made up from 100s lines of trajectories )
however I watched mach3 working - mach3 passes from one trajectory to the next very smoothly
it doesnt stop and go like mine

how can I make my own program same like mach3 ?
sorry this is my best english I hope you understood what I mean

thank you

Mach3 config: Constant Velocity, rather than Exact Stop.

Cheers
