| Step 8: BONUS! Math! | |
| Here's a quick mini tutorial on finding out the value to put into your GRBL settings for the correct amount steps for translating designs into the real world accurately. | |
| A typical stepper motor has 200 steps PER revolution. These are known as FULL steps or 1.8° per step. This setting has the most torque and is the fastest, however not the smoothest. | |
| Most of these machines will list the kind and size of lead/ballscrew it has. On my 3020, the lead screw is 1404. | |
| 14: 14mm diameter of the screw thread (OD) |

| Speaking of Mac OS not seeing it, the "Woodpecker Grbl CNC" board uses the CH340G USB chipset and Mac OS doesn't have drivers by default for this import chip. You can get the driver from Github here (https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver) - just follow the instructions on that page to install the .pkg file |

| Running "vlc -vvv qtcapture://" will initiate a capture window with the default camera while also outputting verbose logs. If you scroll through the logs you will at one point see a list of the available qtcapture video devices. My output looked like this: | |
| [0000000100610128] qtcapture demux debug: qtcapture 0/2 FaceTime HD Camera (Built-in) 0xfa20000016ac850b | |
| [0000000100610128] qtcapture demux debug: qtcapture 1/2 iSight 0xa28100413a366-video | |
| Since I wanted to use the (old) iSight camera (after some trial and error) I added the device ID from above to the qtcapture command (I also changed the destination port to 3000). So it now looks like this: | |
| vlc qtcapture://0xa28100413a366-video --sout '#transcode{vcodec=MJPG,vb=800,scale=1,fps=5,acodec=none,width=640,height=480}:std{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:3000/webcam.mjpg}' | |
