Torch touching plate before every pierce

[Shanghyd]

Need some help. I'm not sure if this is a sheetcam setting or not.
I am using an EzRouter and Sheetcam. The EzRouter is running Mach3 and THC-1000 (IIRC).
I import the .dxf into sheetcam no problem. I do what I need to do in sheetcam and then run the post processor. The problem is that the torch will come down, find the plate, I will hear an audible click, then the torch will raise up, pierce, then cut.
It seems to me that once the plate has been found it shouldn't need to do this on every pierce.
I posted this in the EzRouter forum but I'm thinking its a sheetcam setting.

I did some searching and suspect its in here.


function OnInit()

post.SetCommentChars ("()", "[]") --make sure ( and ) characters do not appear in system text
post.Text (" (Filename: ", fileName, ")\n")
post.Text (" (Post processor: ", postName, ")\n")
post.Text (" (Date: ", date, ")\n")
if(scale == metric) then
post.Text (" G21 (Units: Metric)\n") --metric mode
else
post.Text (" G20 (Units: Inches)\n") --inch mode
end
post.Text (" G53 G90 G40\n F1\n")

dist = 9999999
refdistance = 10* scale
--Put your switch offset value here
switchoffset =.052
lastz = 0
end

What should I change if this is the section?

Thanks for any help.

refdistance = 10* scale, I have changed mine to as high as 500

can you Reverse Run using this post? - i found that doing reverse the Z axis raises about .4 inch and have to rewind the code to recover my job- thx

I used the V button to set the variable and entered switchoffset then put in the value. Then I went to c:\programfiles\sheetcamtng\posts; i click on posts and it brings up a bunch of files i can't open, not sure what it means by open the post using a text editor or where to find the post that the distance, refdistance, switchoffset etc. is. I'm new to sheetcam and mach3 and determined to figure it all out, just need a little help.
