I made my own processor to use in VCarve. It is a nice simple program for Do It Yourself CNC users like me who built their own CNC router. The generic g-code processors on and VCarve / Vectric Aspire did not have the tool notes on the top. And since I do not have a tool changer ( ATC ) I did not see the since in using other post processors that had the extra stuff I did not need.
I made one for Inches and one for MM with arcs. I set the file extension to .nc but I can change it to .tap (Mack3/4) if you want. I use an Arduino GRBL machine with NetBeans ( Universal G-Code Sender ) Click the thumbnail to enlarge.
I own the copyright to this program but you are welcome to use if for free for your own personal use. Use this at your own risk – so make sure you test it with a dry run before trying it out on an actual project.
You can add this nice looking compass to your terrain maps to give them a little more dimention. This map is my home town Muncie Indiana. It was desinged and made by my niece Erin.
You can get the file at Erins site. Click Here

Go to GRBL and click on the code tab, then you will see the download button.
This is probably the number one question, and the answer is: “It depends on who you ask.”
When Simen Svale Skogsrud first sat down and wrote Grbl in 2009, he named it after a bigger version of a computer mouse. It’s small, useful, and doesn’t do much other than what its designed to do. So, if you ask him, it’s pronounced like “gerbil“. If you ask Sonny Jeon, the developer since 2011, he’d say it’s pronounced ‘grr-ble‘, because he was teased too many times by his wife when working on the project. quote from GitHub.
Go to github to get UGS. I like the nightly build myself.
NotePad++ is a nice free editor for your gcode
Prusa has some calcualtors for setting your resolutions. https://www.prusaprinters.org/calculator/
Found out I needed bigger drivers so I am using the TB6600. This meant I can use Arduino UNO but without the cnc shield. For the touch plate / Z probe use the A5 with GND.
If you are using a CNC shield on an Arduino UNO you may wonder why everyone tells you to use the A5 pin on the arduino when it is covered up by the shield.
This diagram of the CNC shield shows where the A5 pin connects the 2 together. So you use the 1st and 3rd pin. Dupont connectors are used, where you see the red and green dot on this diagram. The blue dot (I believe) can be used to run an indicator light.
Here is the GRBL settings on my machine.

You can change the settings right in UGS.
G20 G38.2 Z-.75 F2; G92 Z.057; G91 G0 Z.343
This will stop 0.4 inches from the surface.
For an inside corner plate you could use:
G20 G38.2 X-1.50 F2; G92 X0.125; G91 G0 X0.875; G38.2 Y-1.50 F2; G92 Y0.125; G91 G0 Y0.875
Note: the G20 indicates inches, if you use MM use G21.
Shoot I did not know what I was missing. I knew there was a button that said pendant in universal g code sender but I kind of assumed you had to buy a special piece of equipment for it. But no… you can use your cell phone or browser on you PC or Woo Hooo! I can use my HD8 Amazon tablet with Alexa.
You can do a lot with the pendant,.. jog, send files, reset to zero or use your macros.
I still have my PC connected directly to the CNC, I really would not suggest to run the machine wireless, but all the other stuff sure. My computer is on the other side of a wall so this makes it so much easier and faster to get a job done.
