Fagor alarm 1004: Tangential output programmed wrong

What it means

The movement following a tangential exit definition (G38) is circular instead of straight. The tangential exit concept requires a linear departure path tangent to the previous contour; the CNC rejects the block and halts execution.

Likely causes

• G02/G03 programmed directly after the G38 definition block
• tangential exit defined at a point where the next planned move is an arc
