There are some special codes that can control the ramp (Accel/Decel) on the fly if the angular difference between the current move and the next vector exceeds a certain value but I've never been able to get the hang of how it works. Maybe it's because my CAD spits out too many short moves to allow it to work.
I would love to hear from a guy/gal that has this figured out.
BTW, I have a 2 4020s with Box ways and a 5020 with linear ways. The linear way machine sounds just gawd awful when I try to do surfacing on it. The box way machines are also clunky but nothing near the 5020. I guess their is a reason they quit making them. |
