Siemens alarm 10753: Channel %1 block %2 selection of the tool radius compensation only possible in linear block
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
Cutter radius compensation may only be turned ON in a straight-line block (G0/G1) within the compensation plane, because the offset side must be defined unambiguously by a straight approach movement. Activation inside an arc or helix block is rejected. Insert a linear positioning move before G41/G42.
Likely causes
- G41/G42 written in the same block as a G2/G3 arc
- Postprocessor emitting CRC activation on a curved lead-in
- Helix or polynomial block used as first CRC block
