Y Carriages for the Railcore 250/300 ZL/ZLT

[More Railcore Upgrade Parts]
[Hemera Mount] [Single/Dual (SD) Carriage] [Dual Y Carriage]



Designed for the Railcore II printers, this is a mount for the E3D Hemera, made out of 6061 Aluminum. These are compatible with the direct extruder variant of the Hemera.

The Hemera mount was a joint collaboration with Mandala Rose Works and Filastruder.

The Hemera mount will use the printed carriage version of the James Tongue Shroud and you can download some STLs from Thingiverse for a BlTouch mount , a cable bundle mount and the needed spacer for the James Tongue printed carriage fan shroud.

If you are using the printed Y carriage, you will also need to either print a belt retainer and clip or upgrade to the machined aluminumin one.

The mounting location for the limit switch is built into the Hemera mount as well. Height on the carriage is the same as an e3dv6.

The Single/Dual Y Carriage (SD Carriage) is a replacement carriage for the printed carriage for the Railcore2 line of 3d printers.

This is the same carriage as our Dual Y Carriage, but with additional hole locations so you can use this as a single extruder plate.

The best part of this is if you want to upgrade to dual extrusion down the road, all you need to do is purchase the upgrade kit, which contains a Dual hotend Fan Shroud printed in high temp FunToDo Indistrial Resin, Adjustable Hotend Rail and Ajustable Groove Mount! (Listing for the upgrade kit coming soon!)

See the listing for the Dual Hotend Y carriage kit below to see more information about the upgrade kit.

The Dual Y Carriage kit contains everything you see in the pics.

  • Lightweight Aluminum Y Carriage with spots for 2 hotends
  • Adjustable Hotend Mount
  • Hotend Clip for holding Groovemount Hotends
  • Dual Fan Shroud and mounting brackets printed in High Temp Resin (225C max)

The adjustable hotend mount is locked onto a special rail in the Dual Y Carriage with 2 m3 nuts and bolts. The nuts fit in a slot on the back of the rail, and the screws go in from the side, allowing you the abililty to adjust the height of the 2nd hotend from the front of your printer without having to tear anything apart to get to the adjustment screws. The nozzles are 25mm apart from each other.

The fixed hotend mount uses any of the hotend mounts that we sell, for Mosquito, E3dV6 or J-Head hotends. If you choose to put a mosquito mount for your adjustable hotend, you will have to use a groovemount adapter for it, as the adjustable rail won't allow the use of a non-groovemount adapter.

The Dual Output fan shroud was custom designed for us by James Tongue to work with our Dual Hotend Y Carriage and are provided in the kit as a high temp resin print. Resin is FunToDo Industrial Black or Red and is good up to 225C.

We also have a modified BMG mount, actually, 2 of them. They are designed to fit over the fixed or adjustable hotend and can be downloaded from Thingiverse. The other hotend mount is assumed to be using a bowden setup. Obviously, you may change these as you see fit, or even make an adapter to use the Dual BMG extruder. We have left a lot of choice up to the end user on the implementation of this system.

Please Note: The use of this Dual Hotend Y Carriage will cost you approximate 45-50mm in the Y axis on your printer.

The Mandala Rose Works Dual Hotend Y Carriage was tested and approved by J. Steve White of Railcore Labs.
