# ID 20347

Overflow of channel block buffer.
Description | Between two motion blocks during contouring (G301/G302) no contouring block (chamfer or rounding) can be inserted, because a necessary system resource is not available.
Response | Class | 1 | Continue NC program processing.
Solution | Class | 1 | The NC program is continued without contouring (G301/G302). As soon as the system resource is available again, also the contouring blocks are inserted again. This behaviour shall ensure, that the NC program is completely executed in each case.
Error type | -
