Add coolant to post processor? M8,M9

[beezerlm]

Hello,
Does anyone know how to alter a post that uses M13 as "spindle on flood coolant" to output an M03 and M08 instead? Then use an M09 to stop the coolant at the end of the event? I have attached the post processor for review.

Thanks,

Brandon

Are you sure it is a Post item? Coolant and what type is usually in the CAM portion of setting up the job. There is usually a choice of what kind of coolant. Mist, flood, in tool.

I am pretty sure its in the post because when I select no coolant I get an M3 and when I select flood coolant I get an M13.

Hi BEEZERLM,

I think if you change M13 in this post on the spindle codes section to M03 and save file it should work.

I'm not a post programmer but from doing some minor modifying to some of mine I think it should fix the problem.

always be sure to make a backup before changing or modifying your post just incase you screw it up you have something to go back to : )

if that doesn't fix it send me a pm and I will look at your post more in detail
