D300VS Barbell Carriage and Effector Set

thingiverse

This is a ball-cup arm upgrade set for the Ultibots D300VS, designed for use with Trick Laser/SeeMeCNC fixed-width barbells and Trick Laser Ball-Cup Arms. It also works with the stock Ultibots micro extruder. This set can be used on other Kossel Delta printers using standard 2020 or 2040 extrusions for towers (aligned edge-on to the build surface), as long as the Ultibots micro extruder is being used for the hotend. For the D300VS, use of Ultibots 375mm ball-cup arms is standard, but any arms 340-400mm should work. Other deltas will need to determine their own best rod length. Carriages are designed to make use of Open Builds eccentric spacers on the single tensioning axle. This requires using an Open Builds standard 3mm wheel spacer stacked on top of the eccentric spacer and standard 9mm axle spacers for the other two wheels on each carriage. The pocket for the eccentric spacer is quite tight to the spacer, making it rigid and reliable. You'll need to thread the M5 axle bolt through the hole, slip on the eccentric spacer, 3mm spacer, wheel assembly, and then use the M5 nut to tighten everything down and force the eccentric into the pocket. Effector platform fits without modification to the extruder body but may require filing for clearance issues. If one barbell comes into contact with the top of a corner, simply file the corner of the extruder body for clearance - the section of the extruder where the barbell touches is subject to wear and tear. You'll need to adjust your delta arm length, delta radius/effector offset, reset the bed zero point (paper snag test), and give the machine some extra headroom in the firmware prior to running calibration. Parts as pictured printed in Proto-Pasta HTPLA V3 as prototypes. PLA is functional for non-heated printers but will warp badly if exposed to heat. It's recommended using ABS-PC alloy, CF-ABS composite, or CF-Nylon composite for final parts.
