• 2023-06-19 - updated to acomodate VZ lasercut tool head after plastic melted.
• 2023-04-21 - Updated to work with Offical VZ-PrintablePrintHead - https://github.com/VzBoT3D/Vz-Printhead-Printed
• 2023-02-01 - v4 uploaded and running. (LEGACY)

• Top Mount X Rail
• Simple install just new xy parts and stock standard VZ_Printable tool head.
• No major belt changes just the XY idler belts are now routed to rear of x axis beam. No cuttin no trimming of belts required.
• Ultra lightweigth design with high accelerations. See Input Shaper graphs below.
• 682gram Total X-Rail Full System Install.
• Bed Printable area ~336x ~(y is actually greater to access end stop and brush) 324y

Requirements

• Sensorless homing! Recommend Y home 1st with 100mm back off. Home X 100mm back off. Move Center bed Home Z with BEACON

  • https://docs.vorondesign.com/community/howto/clee/sensorless_xy_homing.html (remember to adjust homing acceleration to 1k)
  • Beacon Probe
  • Umbelical or some kind of no cable chain system.
  • Move the Z-Axis chain under the gantry. and replace the bed mount so they chain can sit tucked under between. - https://www.printables.com/model/279739-voron-can-bus-z-chain-move

• LEGACY Probe Requirements

  • klicky prob
  • https://github.com/jlas1/Klicky-Probe
  • My Custom adjustable KlickyProbe gantry mount that suits custom heights of different toolhead FanDucts in the STL folder.

BOM Build List Of Materials

New Material Requirements.

• 20x20 Carbon Fibre Rod at ~463 mm length
• x4 M5 x 50mm Bolts (preferably Smooth Shaft) (M5x40mm pins work however you can control the idler pressure with bolts)
• x4 M5 x 8mm HeatSet Nuts
• x4 M4 x 18mm cap head bolts (bottom of xy idlers)
• x4 M4 x 12mm cap head bolts or dome (top of xy idlers)
• x4 M5 1mm Shim Washers Re Use of Existing Hardware
• use existing x8 M3 Bolts to mount to y linear rails.
• use existing M5 Washers, Idlers, GT20 Pullys.

Official VZPrintHead Support (MIRRORED),

2023-04-21 VZ PrintablePrintHead Supported. Requirements to use the VZ-PrintablePrintHead mirror the Belt componetns on the X-axis. Mirrored parts are:

zChain Hidden

• Z-Chain under the gantry extrusion is crushed especially with short hotends. Custom length hotend extension can be required. I also designed a new bed frame extrusion mount to allow the zChain to squeeze between. See STL downloads.
