V-Cast 1.5
About the V-Cast 1.5¶
The V-Cast 1.5 was developed as an upgrade to the original V-Cast 1.0 design. It was intended to be an incremental update, rather than a full redesign. It improved upon the original in several ways:
- Complete redesign of the X-axis transmission for both single and IDEX configurations
- Relocated the X and U-axis motors to be inside the frame, decreasing the total width of the machine by 62mm in IDEX
- New three point rigid bed mounting, using the same machined bed plates as the V-Core 3
- Updated Y-axis carriage, which is stronger, yet lighter
- Addition of a second Y-axis motor for additional torque when moving the bed
- Addition of axial thrust bearings & pillow blocks to both Z-axis motor assemblies
Variants¶
The V-Cast 1.5 features the same two variants as the V-Cast 1.0, both of which can be used with either a single extruder, or a pair of extruders for IDEX.
The wider frame, unofficially dubbed the "wide boy", was created to allow the extruder(s) to completely leave the print volume when not in use. This is important for the IDEX configuration as it allows both extruders to reach all points on the print bed, thus enabling the full print volume in multi-colour or multi-material prints.
Kinematics¶
The V-Cast uses standard Cartesian kinematics. Unofficially these are often referred to as "bed slingers", as the print bed (and as such the print itself) moves in the Y direction during operation.
