how do i make the particles keep up?

the emitters are parented to the grinder.
when the grinder moves i expect the particles to go with them!
thanks
PS i removed the back wheels to make the file smaller.

In the file, your emitters aren’t moving with the rest of the machine. Parent them to the body of the machine. Then in the particle system->Bake tab, free the cache and bake the particle system again. Do this for each emitter.

thanks
i never heard of baking patricles before!

even with parenting the particles ALWAYS start in the same place. they don’t move with the emitter.
where is the bake button?

Later I found that if i DONT parent the emitter but give it it’s own ipo thing (I key) then it works!

I did not take too close of a look here but … if you have determined that the emitter does move, but the particles do not, then my best-guess is that far too many particles are being generated, far too quickly.

thanks…

where is the bake button?

In the Bake panel, which is right next to (under?) the first particle system tab. Like I said above, if you parent the emitters, then open the bake tab and do Free cache then Bake, it will work.
