In practice, the machine never reaches the programmed feed because it is always accelerating and decelerating between each co-ordinate.
We are not working to tight tolerances (+/-0.2)
Is there some way of either configuring the control or modifying the CNC program so that the moves are "smoothed" out in order to achieve a higher feed rate?
I'd be very interested to read any suggestions you have.
Thanks
If you program a G98 (?) at the end of each linear feed line it might get rid of the pauses between moves. i'm not sure if it is G98 though.
