Questions for stepper motor gurus | | We have recently installed a new control on our Bridgeport Series II. The machine had been previously fitted with a Centroid control and steppers. We kept the steppers (nema 43, 9A) and bought new drives and power supplies along with a Galil motion card and Camsoft's software.
Just for background info I am new to cnc in general but have pretty good computer, electronics and mechanical skills.
We are having some problems with the steppers and I need to know if I am just heading down the wrong path.
It appears that continuous motion will not be possible. Regardless of feedrate in order to not stall the motors or lose steps we need to decelstop before every feedrate command (G1, G2, G3, etc). Seems like there is a missing ramp up/down.
Is this normal behavior? Does it matter? Am I asking too much of steppers?
Big thanks,
Marc |
