HELP EDITING POST PROCESSOR

liam.carr59V7G — Fri, 24 May 2024 15:17:51 GMT

I have a twin table 5 axis router. I am trying to enable Axis synchronous control (Fanuc 30i B Plus control). basically using both tables as a single bed.

Now I believe I have the Fanuc side set up correctly but I need to amend my post processor so that an M64 is called in to activate Axis synchronous control and M65 is called in to deactivate it.

To confuse things a little, my tool rack is attached to the slave axis, so the ASC is activated after the tool change and once the slave and master axis have been returned to their ref positions with a G28. it is then deactivated prior to any tool change and activated again afterwards.

After any tool change the machine moves to a safe position, So using the G28 in absolute should be ok.

Here is some code of how i think it should look marked in red. I just need to know how to update my post processor(I have attached this)

Is anyone able to provide me with info on how to modify my post please?

You can write your nc program as a cut file and then import the cut file into your post processor and process as debug. There you can double-click on the parameters where you want to add your G codes
