whenever I cut through something say .8inches thick it only goes about .42 into it when its supposed to cut all the way through. the g code is fine I’ve used it on a ez router and it works great. I think there’s an issue with how many turns it takes to go set distance but can’t find out how to access that. the file is accurate and i know the g code works. i checked to make sure everything is secure but I still have this issue. it seems to only go about half the distance it’s supposed to.
Are you bottoming out your z-axis?
Also, does it make even passes all the way down to 0.42, or down to 0.42 and then run the remainder of passes without cutting?
Machine details (hdz/z-plus/belt driven)??

In addition to @David.Curtis’s answer, I’ll note that the number of steps per mm on the Z axis (which relates to the number of turns per mm) is set depending on your Z-axis type in the “Settings” menu in Carbide Motion, when you “send configuration” to the machine.
You can also double-check it this way:
Go to the Settings tab, click “Open Log”, navigate to the MDI tab, send $$, then check the value of the $102 parameter in the log window: it should be 40 for a belt-driven axis, 200 for a Z-plus, and 320 for a HDZ.

I had this once when I had the stock thickness set to a value that was incorrect. I can’t remember my exact scenario but I believe my tool path was set for .750” but my material thickness was different (less then .750” I believe) but the z was set from the top. The first path or two cut in the air and then it stopped well before going through the part because it thought the part was thinner than it actually was.
Now when I am cutting through a part, I always use the spoilboard as my z zero and make sure my thickness is correct. I haven’t had an issue since.
