Description
This alarm (Fanuc Alarm 34) occurs when you are starting (Start-up block) or ending (Cancel block) Cutter Radius Compensation using G41 or G42, and write Circular Interpolation (G02/G03) instead of Linear Motion (G00/G01) in that block.
How to Fix Alarm
To fix this, remove G02/G03 from the block with G41/G42 in your program or from the block following it (G40) and use G00 or G01 there.
