Fagor alarm 1008: There is no information about the previous path

What it means

A G08 tangent arc needs look-ahead data about the preceding path, but none is available within the 48 blocks before the tangent move. The CNC cannot compute tangency and stops the program.

Likely causes

• too many non-geometric blocks between the reference path and the G08
• G08 used at program start or after M30 where no previous path exists
