Fanuc alarm PS0033: NO INTERSECTION AT G41/G42
PS alarm (program/operation) · Fanuc 0i-D
What it means
The intersection calculation needed by cutter comp / tool-nose radius compensation could not find a corner intersection between consecutive blocks. The control cannot construct the compensated path, so the program contour must be corrected.
Likely causes
- Contour blocks too short relative to the cutter radius
- Concave corner tighter than the compensated tool
- Duplicated points or zero-length moves in the contour
