Realignment of Toolpaths
Some toolpaths may move relative to their geometry, on being inserted. This would happen if the cycle had parameters not linked to geometry, such as free digitises and lace angles (which are specified in the 'working CPL' at the time). This is most likely to occur when components are inserted with a rotation.
To avoid this base the cycles as much as possible on entity digitises, to lock them to the geometry.
Post Processors
You can only merge sequences that have the same code generator.
Safe Indexing
Index moves must be performed with the tool at a safe height in all parts. Check this after the merge.
Indexes in parts for insertion should 'Position to Name' rather than 'Position to Angle'.
Component Prefixes
Use 'Name Prefix' in the Insert Component dialog, to aid identification (CPLs, layers, sequences and so on are automatically renamed with appended number's but this can be confusing).
Rotary Milling
The Insert Component and Merge Sequence commands are not supported in rotary milling.
Wire Erosion
Merging Sequences is restricted to the milling and turning environment and will not appear in the wire manufacture mode.
PCI
PCI command recording and playback is not supported for merge sequences.
Turning
Datum shift is not supported by EdgeCAM for turning parts, so all inserted components with sequences must use the same target CPL.
