Secondary spindle on 7i76e

Don't go there Tommy! I remember Bengt was in a lot of pain getting a gearbox working when he converted his mill! I could not bear to watch on the sidelines again!

So for a set of speeds it enables spindle 1 and for the other set of speeds it enables spindle 2. Also you would have to add some offsets attached to those outputs so you do not have to centre the spindles manually, to have it fully automated.

Enclosed find my hal and gearbox comp

And yes Rod I had a struggle to get this all working

it woudt be far better to know what CAD Cam he is using
as it can be interfeared there by Mcode easy to get secondary spindle
the other way is IF the Tolnumbers are fixed to interfear the M6 as a remap and control from there
the RPM go to the both VFD and only the enable and forward reverse are controlled
EVEN as i use on the Woodmill the VFD only got power as they are called by Tx
its just a G4 P3 into toolchange to get time the VFD gets up from sleep

i got alot of pins on the 6axis setup
or on the standard 10 axis bit file
via the 7i92

I use 2 CAD/CAM
More and more Fusion 360 but also my Dolphin Partmaster.

Occasional simple 2D can be via SheetCam TNG

If you don't want to try to use the multi spindle capability in Master. Probably one of the easier ways and one I've used, is to use custom M-codes that control which spindle is receiving the spindle commands from Linuxcnc. But the Hal logic programming can get a little complicated. (That said using Master would probably be easier.) The multi-spindle machines I set up were completed long before the multi-spindle addition to Master and I have no experience with it.

Todd,

As I have the gearbox up and running and what you suggest is my cup of tea.

Custom M code to act on S12000 to S 56000 and reroute the spindle to IO pins on P2 on 7i76e.
