Macro B Fundamentals

Write real Fanuc macros in your browser, from your first variable to a probing routine that writes its own work offset. Nine lessons, each one graded against the same engine the Macro Playground runs.

1. 1Variables & AssignmentStore a number in a variable and use it in another expression.
2. 2Arithmetic & FunctionsDo trigonometry in a macro and know that Fanuc works in degrees.
3. 3Reading Machine StateRead the control's own registers — work offsets and live position — into your own variables.
4. 4Loops & DecisionsRepeat work with WHILE/DO instead of copying blocks.
5. 5The Bolt CirclePut variables, trig and loops together into a real parametric program.
6. 6Writing Back: Touch OffWrite a work offset from a probe result — the pattern behind every probing routine.
7. 7Arguments & G65Read the values a G65 call passes in, and know which letter lands in which variable.
8. 8Alarms & GuardsStop the machine deliberately when a measurement is out of tolerance.
9. 9Named System VariablesWrite the same touch-off with 30i names instead of numbers.
