Riser Features (All Versions)

• Pass-thru Holes: 4 holes in the rear right corner for PTFE tubes. Requires 8 x PC4-M10 Pneumatic Quick Connector Fittings (Amazon Link).

  • Also available is a PTFE Pass-Thru Rear Right Model for those who would like to replace the PTFE Tubes with longer ones opposed to using the PTFE Connectors.

    • Found In Below Folder: "Extra_Long_PTFE_Pass_Thru_Alternates"

• LED Channel: (Original & 45°) Includes a 45° channel for an LED strip and wire. Suggested LED strip: Amazon Link.

⚠ Important Installation Notes:

• The PTFE tubes from the print head to the corner connectors need to be cut to a target length of ~500mm. This shortens the run and prevents the tube from getting coiled into itself.
  

• Ensure the connector holes on the corner part can clear a PTFE tube going through them so they meet end-to-end within the connectors. This ensures smooth filament pass-thru without snagging.
  

2. The Canvas Unit

This system relocates the canvas attachment to the center-side between filaments 1 & 4, utilizing a new dock and slider mechanism.

• Canvas Dock Plate: Connects to the top center screw between filaments and attached to the Dock Anchor Part.
  

• Canvas Slider Plate: Attaches to the back of the canvas unit to slide into the dock, making removal for troubleshooting much easier.
  

• Cable Clip: An additional block that holds the canvas cable, preventing tangling with the spools.

  • Attaches to the top of the Spool Holder Bar using the top screw positioned behind Spool Number 4

3. The Right Side (The Update)

The right side is split into two distinct pieces to accommodate the canvas bracket screws and provide a better anchor for the dock.

• Upper Right Side Panel: The top section.
  

• Lower Right Side Part: Uses the screws from the canvas bracket to hold in place and has an extended piece acting as an anchor for the dock.
  

• Modified Dock Part: Features an anchor on the back to attach to the Lower Right Side Part for added stability.
  

Installation Tip: Install the lower "Anchor" before installing the Dock. The dock uses the center screw between Filaments 1 & 4 to hold it in place along with the anchor part.

PTFE Tubing Configuration & Measurement Guide

Please measure first before attempting any cuts!

• A. The Main Run (OEM Print Head):

  • Source: Original OEM PTFE tubing.
    

  • Target Length: ~500mm.
    

  • Measurement Point: From the farthest corner opposite of the PTFE connector (measure from the top of the hub to the end of the tube).

• B. The Feed Lines (Canvas Unit):

  • Source: Purchase new or repurpose leftovers.
    

  • Target Length: 220mm.
    

  • Measurement Point: From the insertion point in the Canvas unit to the end of the tube.
    

• C. Variables & Variability:

  • Port Dependency: Depending on which specific tube is routed and which port connection is utilized, effective length may vary slightly.
    

  • Tolerance: Aim for the target lengths above, allowing for a ±5mm variance based on port geometry.

LED Light Wiring (Optional)

⚠ Caution: Attempting to wire or solder carries risks of personal injury or incorrect wiring if done improperly.

• LED Bracket:

  • Found In Below Folder: "LED_Light_Bracket"

    • JST Connectors Used: https://www.amazon.com/dp/B0D6KSMK1Q?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_6

1. De-solder the old LED light.

2. Solder the new cable to the new LED light (Positive to Positive, Negative to Negative).

3. Solder the existing LED light cable to the bracket (Note: Take note of which pin is positive/negative on the bracket).

4. Mount: Bracket screws in using the old hardware.
