Testing cut, observe cutting section to judge if the focus point is too big or small. Slag (too big), Grain (to small).
Turn on the focal point control panel before cutting head to do manual focal point adjust.
When focal point data is 0, turn the focusing wheel to the left, then do cutting test.
When the focal point data is too small, there is slag at the rough bottom of the surface of the cutting sample (the focus is too small to cut through).
When the focal point data is +5 or bigger, turn the focusing wheel to the right, then do cutting test.
Cutting surface has obvious pattern on when the focal point data is too large.
After cutting test, observe the cutting surface and adjust the focusing wheel till the right data.
When the focal point is at the right place, the surface of the sample is smooth and without hanging slag.
Finish the testing.
Focusing adjust for carbon steel ( the same as manual laser cutting head focusing)
Focusing adjusting for stainless steel (the same as manual laser cutting head focusing)

A computer controlled (CNC) mill can turn digital 3D models into metal parts with ease. However, turnkey CNC mills are often too expensive for the garage DIYer who doesn’t plan to turn a large profit. Dr. D-Flo took the more affordable approach and converted a manual Precision Matthews mill (833T) to CNC by swapping in ball screws and stepper motors. While the mechanical portion of this video is specific to the 833T, the electronics and software can be used in any mill conversion or the creation of any large CNC machine for that matter. Learn how the Mesa7i76e controller board, LinuxCNC, and Probe Basic work together to translate user input and 3D models to real life movements of the mill. This addition to the Dr. D-Flo garage has acted as a catalyst for some awesome upcoming projects so get subscribed!

This video is for the Concord Kids – a group of 5th grade students studying STEM! And, of course, it’s for anyone to serve as a basic beginners guide to a manual milling machine (Bridgeport) and a computer controlled CNC Milling machine (Tormach PCNC 1100)!

Curious how we film? http://bit.ly/2q8MfoV

Their teacher, Dan, email saying a video on milling basics would really help the kids understand some of the work they are studying. I love helping kids and would encourage everyone to reach out to any number of local programs – STEM, FIRST Robotics – anything to help increase interest and passion for engineering in our youth!
