Fagor alarm 1001: Plane change in rounding/chamfering.
CNC 8055 CNC error · Fagor 8055/8055i
What it means
A work-plane change was programmed in the block immediately after a controlled corner rounding (G36) or chamfer (G39). The CNC needs the following path in the same plane to compute the blend, so it refuses to execute the block and stops the program.
Likely causes
- G17/G18/G19 (or G16) programmed right after a G36/G39 block
- plane switch hidden inside a macro or subroutine called between contour blocks
