modifying post processor for drilling

[metalman23]

I have a premier plasma, i ran a simulation to see what the gcode looks like if i ran a drilling operation, but in the gcode i can still see the command "Z-100" for the floating head ,

can i change that setting in sheetcam, or do i delete that line from the post processor? i want to clamp a spring loaded center punch into my torch holder, so i can use the table to mark out holes for me to drill out on the drill press


i tried deleting the lines from the post processor, here's my 2 gcode files, which is a bunch of "holes " in a straight line left to right

one file is with the stock premier plasma post,

adn one is with the modified post,

i'm a noob to gcode so does this gcode look like it would "drill" a hole with no problem?

Are you using the 'PremierPlasma CNC floating head' post?
I had a quick look at the post and if you just want to get rid of the referencing code when marking it's pretty easy to change.
Edit the post and look for function OnPenDown() which should be near the middle of the file. The first two lines of the function should look like this:

Code: Select all

   function OnPenDown()
   if(dist >= (refdistance/scale)) then

Change it to:

Code: Select all

 function OnPenDown()
   if(toolClass ~= "PlasmaTool") then return end
   if(dist >= (refdistance/scale)) then
   

That way it will only generate the reference and piercing code for a plasma tool. With your drill tool you'll just get the moves from function OnDrill which simply move down to the drill depth then back up again.

Yes I'm using the floating head post, Thank you! I'll try it out and let you know how it works
