HEIDENHAIN 280-03F7 - Too many points

Too many points

Maximum point storage exceeded during digitizing range creation. The system can store up to 893 points.

Root Cause Summary

HEIDENHAIN alarm 280-03F7 occurs when the digitizing point buffer exceeds its maximum capacity of 893 stored points during manual data input operations. This typically happens during extended touch probe digitizing sessions or when the point storage buffer is not properly cleared between operations.

Safety

  • Refer to Heidenhain service manual
  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    Access digitizing point memory

    Press MOD key, select 'Touch Probe' menu, then 'Point Memory' to view current point count and stored digitizing data.

    Check the point counter display to confirm you're approaching the 893-point limit

  2. 2

    Clear digitizing point buffer

    In Point Memory menu, select 'Delete All Points' or use DEL key to clear individual point sets. Confirm deletion when prompted.

    Ensure important digitizing data is saved to part program before clearing buffer

  3. 3

    Optimize digitizing strategy

    Break large digitizing operations into smaller segments, saving critical points to program variables or datum tables between sessions.

    Use preset point patterns or reduce sampling density for large surface digitizing operations

DIY Feasiblehigh confidence

Call a technician if:

  • ·Memory corruption persists after reset
  • ·Probe hardware malfunction suspected
  • ·Machine parameter corruption

Prevention

  • Monitor point count during extended digitizing sessions
  • Clear digitizing buffer between major operations
  • Optimize point spacing for required accuracy
  • Regular backup of digitizing data

Common Mistakes

  • Not clearing buffer between jobs
  • Using excessive resolution for simple surfaces
  • Ignoring point counter warnings
  • Attempting to digitize entire complex surfaces in single operation
