SolidCore CoreXY Y-Carriage
Hotend Mount to Y-Carriage Assembly Diagram
Aluminum carriage for the SolidCore Printer
Available for MGN12, MGN9 linear rails
Y-Axis Linear Guide Design Options
The goal is to have a modular carriage assembly with interchangeable print heads. The carriage was designed to be lightweight but strong and interchangeable. The all-metal design uses “c”-shaped aluminum channels to reduce weight and machine time. The current design mounts to a MGN12 and MGN12-H linear rail but a MGN9 is also available to reduce weight and increase travel distance.
Toolchanger
We plan to adapt an E3D Toolchanger eventually and are prototyping tool changing options.
Gantry Movement & Motion System
Balancing the pull to the center of carriage instead above it or below seems to be more rigid and minimize deflection. The belts should run along the same plane as the linear rails depending on pulley and belt brand used. To avoid rocking along the x-axis and belt tensioning issues, keep the belt path as parallel as possible with the x-axis with proper spacers to minimize vertical movement of the idler pulleys.
Belt Tensioning
The SolidCore uses a simple belt tensioning design where the XY-stepper motors move within slots to tension the belt system rather that belt tensioning on the y-carriage or gantry.
