February 27, 2023

In Part 1, we set up the Arduino & GRBL shield. Now, let’s use inexpensive linear motion hardware (links below!) to assemble the bearings, rods and steppers into a functional CNC machine!

Products used in the video:
Arduino Uno: http://amzn.to/1E0gxVU
Linear Bearing Slider: https://amzn.to/2GYeRWU
GRBL Alternative for Arduino CNC: https://amzn.to/2IgMH8Y
GRBL Shield: http://bit.ly/1vJbWY9
24V Power Supply: http://amzn.to/1BlwmF4
Multi-Meter: http://amzn.to/1qppo2C or http://amzn.to/1siEp1C
8MM Linear Rail: http://ebay.to/14rPWXB
Stepper: http://ebay.to/1xNEJ02
Timing Pulley: http://ebay.to/1I25PEN
Timing Belt: http://ebay.to/1xNxthz
Dial Indicator: http://amzn.to/1DuvGQC
Indicator with Mag Base: http://amzn.to/1ABvkba
2-4-6 Blocks: https://amzn.to/2IgQrHo

In this video, we look at the CAD model of the machine, discuss basic design philosophy, test it’s accuracy (amazing results!), then do the final GRBL set up so that we can export CAM G-Code to use on the machine!

We just added a Part 3 with a Z-axis upgrade! Check it out at https://youtu.be/gzLYNSQEPDk

Cut Accurate Size Holes w/ CNC Router, How To CNC Woodworking Tips And Tricks For Beginners v-carve

admin

February 8, 2023

Getting exact hole sizes in your woodworking projects with a CNC router is a known issue and there is a way to get the holes to the EXACT size.

Making holes the exact size requires a bit of understanding of how the program is set up. This trick will take you to the next level with your CNC router.

The tips in this video show you how the industry compensates for a well-known issue and how to compensate for it.

The reasons hole sizes vary are many..material variations, size of the hole, the machine, cutting tool, etc.

All cnc software has features that allow you to take this into account. It will be called “allowance” or “offset”. This will tell the program how to write the code to run holes with your CNC router.

When you enter an offset, you are telling the software to add or remove that amount from the tool diameter
