OrcaSlicer V1.6.4 Beta Release

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

• 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

• 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

Localization:

• Russian translation by @stasyan68 in #1509
• Ukrainian translation by @djperya in #1638
• Korean translation by @Hotsolidinfill in #1664

OrcaSlicer V1.6.3 beta

Changes:

New features:

• New calibration tests, refer to WIKI for more details

1. Retraction
   
2. Orca Tolerance Test
   

• Improve bridging for classical wall generator when only one wall on top surface is used.
  

• Fan Speed Delay + Fan Kickstart Feature by @scottmudge
  This feature enables the fan to start earlier than its target start time in order to compensate for the fan kick-in time.
  

• Support full_fan_speed_layer feature #85
  Fan speed will be ramped up linearly from zero at layer to maximum at layer full_fan_speed_layer
  

• Number of slow layers #796
  The first few layers are printed slower than normal. The speed is gradually increased in a linear fashion over the specified number of layers.
  

• Support interface fan speed #881
  This fan speed is enforced during all support interfaces, to be able to weaken their bonding with a high fan speed.
  

• Streamlined WIKI Publish. Many thanks to @chrisribe

• Merge BambuStudio v1.6.2 beta changes, including:

• Advanced cut with connectors: Thanks to @prusa3d for implementing this cool feature, and Bambu for porting it.
