For example, bugs in the post cannot be detected this way because the post is downstream of that geometry info. This allows for subtle bugs to creep in that are not detectable in the CAM backplot. They just plot the same geometry information that was used to create the g-code output by the postprocessor. If your CAM program includes a true CNC g-code simulator, then yes, it can be used to help test g-code programs. The qualified answer is, “Probably Not.” The issue is the way CAM program simulators work.
#Gcode viewer software
Not so fast! Doesn’t my CAM Software already have a Backplot / Simulator for this purpose? I’m sure many of you are thinking, “Yup, I use the g-code simulator in my CAM Software all the time!” You’ll also hear the terms “Verification”, “Emulation”, and “Virtual CNC” batted around, though they’re a little less common than the other three. You need a piece of software that has variously been called a G-Code Simulator, CNC Backplot, or NC Viewer. It’s actually cheap and easy to run a G-Code Simulation. What if there was a better way to get a second opinion and test your gcode? One that didn’t tie up the machine and that could be done much more quickly than Cutting Air? That’s what G-Code Simulators are for.
#Gcode viewer how to
If you must Cut Air, here’s how to do it: The trouble with Cutting Air is it can be very time consuming and it ties up your expensive CNC machine the whole time. Cutting Air is the least you should do to test (also referred to as “proving out” a part program) your gcode part program. “Cutting Air” just means running with part zero set high above the workpiece so the cutter (hopefully) doesn’t come in contact with any material until you see what it will do. Testing can range from “cutting air” to using a G-Code Simulator. You Don’t Run G-Code Without Testing It, Do You?!? ( Better not let the boss find out if you do… ) Use a G-Code Simulator to Test and Prove Your G-CodeĬonsidering what can happen if there’s a mistake in the gcode, and even CAM software makes mistakes sometimes, you want to test your gcode before you run it to make chips. 5 Ways G-Code Simulators Crush CNC Errors
