Anet A8 Plus Stealthburner Conversion

Project done in collaboration with @Print3DPilot

We wanted to upgrade an Anet A8 Plus to a Stealthburner. 

We initially thought the Voron Legacy part would be a drop in fit but the distance between linear rod centres were 40mm vs ~50mm on the stock A8 Plus.

Print Settings: (Standard Voron Settings)

• ABS or ASA
• Recommended Cubic Infill
• Recommended 40% Infill
• 4 Shells
• 5 Top & Bottom Layers
• 0.4mm Nozzle
• 0.2mm Layer Height
• Print X Gantry Pieces Upside Down

General Notes:

• Linear rails have 3mm of float on the Y-Axis 
  • There are a pair of optional screws to move the linear rail out on the idler side
• Features Prusa-Style Square Holes in the X Gantry End Pieces for linear rod visual inspection
• The 4 heatset inserts for the lead screw nut have very thin walls so care is required to prevent overheating of the wall or wandering of the insert
• The X Gantry End Pieces are inspired by 
  • https://www.printables.com/model/43577-am8-bear-extruder-x-ends
  • Initially it was supposed to be a remix but I started from scratch
• The Stealthburner X Carriage was remixed from the Voron Legacy Project
  • https://github.com/VoronDesign/Voron-Legacy

Note on Belt Mount Bolt Direction:

• The Belt Mount & modified X Carriage are designed for screws inserted through the back of the carriage or through the front of the carriage
• The recommended method is inserting the screws from the back of the carriage and inserting the heatset inserts into the X Carriage instead of the front allowing for removal of the Belt Mount without removal of the Stealthburner
• The stock X Carriage requires the removal of the Stealthburner to remove the belt mount
• The Belt Mount should be installed with the open end facing the X Carriage to retain the belt
• A short and a tall Belt Mount is included to move the 1mm higher or lower for better belt routing and compensating for tolerance stack-up
