This video tutorial explains how to set up your router bit start point for your CNC router projects. You will learn how to set the X Y Z zero locations to the exact start point of your project.

Setting X & Y time stamp: 7:28
Setting a router bit to the exact corner is easy and can be done fast without the use of a tool probe. This technique is used by professional CNC machinists routinely. In the times when they needed higher precision, that’s when they use probes to assist.
As a CNC beginner (or even a pro,), this method is completely adequate for woodworking projects done on a CNC router.
Setting the zero point is easy.
Know the diameter of the tool
1. Use the paper method to set the Z height
2. Touch the edge of the material while turning the tool by hand. When you feel the tool touch, stop and set zero
3. Touch the other edge of the material in the same manner and set zero
4. Raise the tool above the Z surface
5. Enter in the command line “G20” (if you use inches), “G21” (millimeter) and hit enter
6.Divide the tool diameter by 2 (example…0.25 tool is 0.125 when divided by 2)
→ 0.125 is used in the example below. Make sure to enter your divided number
7. In the command line enter “G0 G90 X0.125 Y0.125” and hit enter
8. Set X and Y to Zero on your controller.
Your exact position is now set
