Part 4 – Separate Last Pass, Tabs, Post Processor, and G-Code
This article accompanies the fourth video in a series on my YouTube channel. If you’re not subscribed to my channel, here’s a link. Come on by and check it out. Hopefully you’ll find something you like.
FIRST THINGS FIRST
While this series might seem like going back to the basics to the seasoned veteran, people who are new to CNC in general, and CAD/CAM software in specific, are joining Facebook groups and message forums every day. I frequent a lot of those forums, administrate a few Facebook groups, and am a member of several others. As a result, I’m seeing a lot of posts from beginners who have never done anything in CAD/CAM software, asking questions on some of the very basic tasks involved in using CAD/CAM software.
In this fourth video of the series, I’ll go back into our clock face file that we created in Part 3, and answer a question on resizing. Then I’ll switch over to the Toolpaths tab and demonstrate a few of the options in the Pocket toolpath and Profile toolpath that I kept putting off “for another video.” Among these are Pocket Allowance, Separate Last Pass, Adding Tabs, and Adding Ramps to your toolpath.
Lastly, I’ll demonstrate how to choose the correct Post Processor for your CNC router, save G-Code, then open that g-code to give you a look at the instructions your controller will send to your CNC to cut out the project.
A FEW THOUGHTS
For the seasoned veteran; I would ask that you please remember that none of us were born with this info. We didn’t just magically start knowing this stuff. Every one of us had to learn it. So if something seems like it should be common sense to you, remember that the person who taught you thought the same thing. No, you probably don’t need a lot of the info contained in this video, or even in this series. But if you decide to check it out, hopefully you’ll pick up a tip or pointer here or there, or at least get some insight into what the absolute beginner wants to learn. Maybe you could start sharing your expertise with others as well. This hobby can never have too many teachers.
For the absolute CNC beginner; don’t stress over any of this. It’s supposed to be fun, remember? You CAN learn this. You CAN do this. It’s not always super easy, but it’s never really super difficult, either. Just like anything else you want to do, there is no replacement for experience – and the only way to get that experience is to practice. Get into your CAD/CAM software, and learn it. Draw in it. Calculate toolpaths. Generate g-code. You don’t’ have to cut anything with it – it’s more important that you learn how to use the software than it is to start making chips.
GET ON WITH IT ALREADY!
That’s enough jabbering from me. Below is a link to the fourth video in the series that’s geared toward the absolute Vectric software beginner.
I use VCarve Pro version 9.015 in this video, but all of the information in the video applies to Cut 2D, VCarve, and Aspire software – both the Desktop and the Pro versions.

I read ALL of the messages I get through my website, and I answer as many as humanly possible – unless you’re a spambot. Spambots get blocked – so there.
Remember, beginners – relax, take your time, and enjoy the process. It’s supposed to be fun, remember? You can do this. I’m living proof.
