Release 4.7.2
A focused patch release for SLA memory use and support generation, plus CAM helical thread-milling controls and drill travel-boundary handling.
SLA / MSLA
- reduce SLA hollow-shell memory use by removing FDM-style solid projection from the SLA shell path
- reduce memory pressure in threaded SLA slicing by passing point arrays directly to minions
- improve SLA support generation performance
- improve SLA support progress reporting during contact collection, clustering, and route planning
- prevent SLA support trunks and branches from intersecting the model
- add slice crash progress breadcrumbs that report the last known stage after browser reload
CAM
- add helical operation entry conditions for neutral, center, inside, and outside entry
- add helical operation exit conditions for neutral, inside, and outside exit
- preserve legacy center-entry behavior while exposing the new entry condition control
- make center entry offset visible only when center entry is selected
- fix helical operation tooltip misspellings
- establish travel move boundaries for drill operations
FDM / Slicing
- reduce minion memory retention by sending slice point arrays with each threaded slice request instead of caching them in minions
