Using WHILE and IF in Macro B

6/1/20 8:00 AM / by camInstructor Mike

Making a program that will face ANY size block using Macro B. This was taken from one of our YouTube Live Streams.




This video is pulled from our last live stream. The full stream was roughly an hour long.

Stream starts at about 5:11

Basic g code is just a way to 'connect the dots'. Custom Macro B allows the programmer to put some logic into the g code with tools such as loops and branches. It also provides additional Math functions and the ability to access information from the machine. Custom Macro B programs can be simple, they can be complex. From custom canned drilling cycles to probing routines to cutting simple shapes, there's almost nothing you can't do with Macro B programming.
