Title: Index and timing in M3-Turn
Post by: jwhalin on November 15, 2019, 04:01:32 PM
Will Mach-3 work using both the “index” and “timing” inputs set to different input ports?

I would like to use the INDEX for starting the threading operation in M3Turn and the TIMING for smother RPM control.

The timing input would have 8 or more “triggers” on one spindle diameter while the “index” would have only one trigger on a different spindle diameter.

Is there a better way???   Thanks.

If you use timing only one slot needs to be wider so mach can use it as the trigger.

Thanks for the response, My plan was/is to use "Hall Effect" sensors.

I'm not sure how to make one trigger for a longer period. This is why I was going to use two sensors. 

Maybe I only need the index, I assume it will also provide RPM to Mach3 as well.
