Jabberwocky Errata - kinematicdigit/Jabberwocky GitHub Wiki

Below are issues that were corrected for the Batch 2 and Batch 1 releases.

V82 Parts

  • Split Mount - new carriage mounting system for higher tension AWD systems
  • Front mount block plate - now includes a keyhole so the mount screw can be preinstalled in the conch mount to receive it
  • LED_Carrier_LDO - tighter tolerance for better fit
  • NH36 Mounting Bracket - Slimmer design for better wire management
  • NH36 Mounting Bracket Strain Relief Offset - new tube offset that keeps it away from the main cable
  • Shroud Body - Wire channel updates and deeper channels
  • Blade Holder LDO - new print orientation to make it stronger and easier to install
  • Conch Mount - Corrected for some misalignment issues if the screws were too tight. The mount screw can now be partially preloaded to make installation on the carriage mount easier. New print supports
  • Bearing Install Cap - smaller install cap so it can be used for installing bearings in both motor and mid-body
  • Mid Body ECAS - geometry and engineering changes to improve flow (improvements made to address some poorly tuned prints or to compensate for build quality/user skill). A new bearing void profile has been engineered, and an improved boss helps ensure correct bearing installation. These improvements will also extend the life of the motion parts. ECAS bodies and P4-M10 body options have been strengthened.
  • Motor Mount - geometry and engineering changes to match improvements made in the Mid Body. Additional countermeasures were implemented on the motor mounts to prevent over-tightening of the main drive gear, which could cause excessive wear.
  • Guidler - adjusted geometry to compensate for improvements made in the mid-body
  • Front Cover - small adjustment made to improve printing
  • Several removable print supports have been redesigned and use wave supports to make it easier and cleaner to remove.

V81 Parts These are minor updates to get rid of small holes and missing counterbores. This is not a necessary update for users who have V80 parts.

V80 Parts New Mid-body and Motor Mount for the Extruder has been released. Use this for both Batch 1 and Batch 2. This eliminates the need for using the two M8x.5mm spacers that are part of the bearing stack for the drive idler gear. A new push-fit installation tool has also been included. This version removes some tolerances and makes it easier to assemble the bearing assembly without the spacers falling out.

Nozzle on Conch (Batch 2) Please check that the nozzles that were shipped with Batch 2 kits are tight. They should be hot-tightened after initial startup. This should not be tighter than hand-tight. If you have a nozzle torque wrench, this should be no more than 1N. Batch 1 Conch are integrated nozzles and do not require tightening.

Front_Body_Emount (Batch 2) Printed part has been adjusted to allow for the soldering glue used in the new construction of Logo neopixel in Batch 2.

Motor Mount Gear Mesh (Batch 1) For immediate release. The adjustment motor mount hole has been reduced to prevent the gears from losing mesh. It is recommended to replace this part to prevent the motor from slipping and causing damage to the LGX drive gear. The updated file is located in the project GitHub repository. This is now integrated into the V80 update. An optional printable washer is also available, which is a simple, temporary drop-in solution that will prevent the loss of gear mesh.

Filament Sensor Wiring Harness (Batch 1) For Batch 1 kit owners, please be aware that the yellow and black wires in the wiring harness for the filament sensor switches are reversed. The pins need to be swapped to ensure correct functionality before completing the installation.

Loose Guidler T-Nut (Batch 1) The T-nut used for the Guidler assembly may be loose, either initially or over time. It is recommended during the build to stuff the hole with three short pieces of 1.75mm filament to secure the nut. Once the filament is inserted, cut the ends flush. The nut will be held securely in place by the motor mount after assembly.

Switch Depressor Alignment (Batch 1) To prevent misalignment of the filament sensors, the depressors on the switches must align with the latch side of the extruder body. Please take a look at the build guide for image references. Once installed, test the alignment by inserting a piece of filament and listening for the audible "click" of the switch.

Conch Mount Screw Update (Batch 1) A late update was made to the design after kits were finalized. The lower portion of the Conch Mount now utilizes two M2.5x8 screws. These screws eliminate the need for the drop-in T-nuts and top-mounted screws from the original design, making them redundant. This change also simplifies the removal of the hotend for maintenance.
