Note: Robo3D R1+ ramps boards do not support dual extrusion. You would need to replace the Ramp1.4 daughterboard to run dual extrudersThis is a simple replacement carriage for the RoBo 3D printer designed as a drop in replacement for the existing carriage. Should be able to print without support for all parts though support on the Fan holder might be a good idea. Fan shrouds work for either the Chimera or Cyclops. Update 2/28: I added a new revision of the base carriage with the correct 15mm diameter for the bearings. Please download v2Instructions are still in progress.
