Just for reference, the values you need to enter are in MM, not inches. I just got my scribe operational today using the scriber post, and it works fine. However it didn't at first until I realized that it wanted metric values.
In my case if you're looking at the torch head on, my scribe is to the left (2.316 Y+, .077 X-. My values are those numbers converted over to MM, and then reversed from positive to negative.
So my Y number is negative in the post and my X is positive.
--Scriber X,Y,Z offsets
scriberX = 1.195
scriberY = -59.85
scriberZ = 0
Use a tool of 101 and above in Sheetcam. I set my engraver kerf to around .021 using a carbide tip.
