Make arc in W axis

Hi...so one more question...I was thinking to drive 2 tools off same axis from computer...the only thing is that they have different scales..meaning one is screw...other is gear....almost 10 to 1 difference...I was thinking of using 2 different drivers with different microstepping...does not seem to work...any other workarounds?

Thanks,

It most certainly can work. But you may need to be a bit clever, and not do everything in the conventional fashion. I recently set up a gang-router that uses 8 independent joints for 8 independent Z axis spindles. While the config I made does have each of the spindle joints using the same motors, and screws with the same pitches. Nothing in that configuration would preclude any of them from having different scales. Each of those spindle joints have their own independent scale settings.

nothing worse than being wrong about being wrong!..I thought it should work but when I tried it ..seemed not to...ended up being a stuck dip switch on driver...Now I was only using driver dip switch to get equal movements on 2 totally mechaicals...one a screw..the other gear...is it possible to set up different scales to same axis for different motors?

Thanks!!

Are your two parallel axis to be rigidly fixed together like the two ends of a gantry or are they going to be independent parallel motion, that you might not necessarily always want to move together? If it is the latter then you might want to check out my gang router config (it is posted here on the forum.)
