SoftFever/OrcaSlicer v1.6.4-beta

OrcaSlicer V1.6.4 Beta Release

on GitHub

OrcaSlicer now has an official Discord server OrcaSlicer Discord

What's Changed

• QoL improvement: Orca Slicer now remembers each printer's filament, bed, and process settings, making it easier to switch between multiple printers

• Single wall on top surface for Arachne by @Noisyfox in #1583
  

• Pressure Advance: add Ellis' pattern method for pressure advance calibration by @thewildmage in #1547
  

• Some other updates for Pressure Advance calibration:

  1. Speed: All PA calibrations now use minimum speed at 100 mm/s (still subject to max flow rate) as PA effect is not obvious under slow speed (one also probably doesn't need it when printing at 45 mm/s speed).
  2. PA tower: Only one wall will be printed for most nozzles (0.4 upwards).

• Make Overhang Printable by @Noisyfox and @odie5533 in #1615
  This feature based on Cura's ConicalOverhang algorithm by @BagelOrb
  

• Support for using a percentage (%) of nozzle diameter to specify line width by @iFallUpHill in #1578
  

• Add Lift Z only Above/Below, On Surface (e.g. Only on Top) by @iFallUpHill in #1562

• Optimise sandwich wall mode when perimeters are shared with multiple islands(Arachne only) by @igiannakas in #1352
  Previously, in cases where sandwich mode was used, Orca would fallback to inner-outer wall order in certain edge cases. Now, it will fallback to outer-inner wall order.

• Display print end time for in BL device page by @ZdDroid in #1568

• Add option for skirt-speed override by @scottmudge in #1371

• Optimized GCode Generation: significantly reduced the number of M106 commands to address the "timer too close" errors experienced by some Klipper users when printing with dynamic fan speed setting on. #804

• Improve z seam performance:

  1. Turn off wipe_on_loops by default
  2. Change default wipe distance to 1 mm
  3. Reduce Seam gap to 10% by default

• Overhang tweaks:

  1. Revert back to classic overhang slowdown
  2. Support percent for overhang speed

• Tweak profiles for Voron/Qidi X Plus3/etc

  1. Fix Voron Trident printable height issue #1641
  2. Revamp Qidi X3 printer profiles
  3. Turn on accel_to_decel_enable for klipper machine by default
  4. Many other profiles tweaks

• update latest BL profiles from BS 1.7.1, adding P1S profiles (Note: only BL machine profiles from BS)

• Port PrusaSlicer staggered_inner_seams

• Bugfix for zero-width tree supports by @scottmudge in #1367

• Fixed an issue that Orca Slice can't connect a printer that uses http protocal on Mac by @ammmze in #1157
