G41 output only on Finish pass

[Manuel0822]

Does anybody know how I can get a post to only output Cutter Comp only on finish passes on 2D contour using multipasses??

Hrmmmm, this is a fair amount of work.

First you have to know if multi passes are enabled prmcode = 15214

Then you have to know how many roughing passes were programmed prmcode = 15560

Then you have to know how many finish passes were programmed prmcode = 15380

Then you have to add the roughing passes & finish passes together to get the total number of passes programmed... sum of 2 above variables

Then you need a counter in the plinout postblock that would be triggered by the compensation on position cstart$ = 2000

Then you need to find were the G41 comes out from and put that section of code into brackets.... something like...

         if 15214 = 1,
             [
             if counter = total number of passes,
             G41
             ]
        	else, proceed as usual
    	else, proceed as usual

There is more to it that I listed (defining variables, pulling parameters.... etc...), but that should get you started

My favorite way to fix things is duct tape, so take it FWIW.

LMAO

 

Thanks Keith I see now it will be quite a job to get it going, I'll see what I can do.

do it in 2 ops,one rough without cc, and the other finish with cc

"do it in 2 ops,one rough without cc, and the other finish with cc "

 

doesn't work if you try to keep your tool down between passes

It will if you play with the linking parameters... I have done it.

really?? I tried it too using the incremental values for retract and top of stock and some other but haven't figured out how to get it to work to just get me a G41 on the last pass. Besides that I have 2 chains on this op.

[K2csq7]

2 operations, 1st has 3 roughing multi passes (no finish passes and no cutter comp), 2nd has 1 finish pass (no roughing passes but with cutter comp)

got it, I gues I didn't pay attention while reading, I thought you meant it'll do it using a single toolpath
