Path Rules - insert code before M3 ?????

[beefy]

Is there any way with path rules to insert a code snippet BEFORE the M3 ????

You would likely need to modify the post processor, contacting Les at SheetCam may be the easiest way.
In the post processor there is a function "On Open" where commands dealing with the floating head or ohmic sensor may be where these commands could be installed. There are some here that understand the codes and placement that may comment, I am not one of them.
You can contact Les from here or go to their web page and click on "contact us" to send an email.

Just search the post for M3 and add the code before it. It could possibly appear multiple times, but usually just once.

Thanks lads,

I'll contact the master.

Possibly as part of the OnPenDown() function within Sheetcam

You could add your own lines as post.Text there is a section generally for flame as well as plasma.

function OnPenDown()
CheckFeed()
if (preheat > 0) then
post.Text (" M800")
post.Text (" \n")
post.Text (" G00")
post.ModalNumber (" Z", cutHeight * scale, "0.0000")
post.ModalNumber (" F", plungeRate * scale, "0.0###")
post.Text (" G04 P")
post.Number (preheat * 1000,"0.###")
post.Eol()
end
if(tool >= 100) then
etc

Cheers lads.

Responded on the Sheetcam forum too.

Yes I'm able to do things with a variable and the post processor, but just wondered if I'd missed anything in the Path Rules that would have made it simpler. It appears the Path Rules can't do anything outside of M3/M5 so variables it is.
