G2S 3-Bearing Carriage

thingiverse

This is a new carriage designed specifically for the Geeetech Delta G2S printer. It boasts three linear bearings, significantly enhancing lateral stability compared to the standard two-bearing carriage. The spacing between diagonal rods closely matches the original setup but is mounted as high and close to vertical rods as feasible. You will need to modify your firmware's dimensions after installing this carriage. The Carriage Base is a substantial and intricate piece that can surprisingly tolerate noticeable warping at its corners while still producing an entirely functional unit. The critical alignment in these structures is strategically located away from areas prone to corner warp zones. As the bearing covers are marginally taller than their originals, I had to lengthen my Servo Carriage Latch slightly. An updated version of this latch has been incorporated into the design. You will need to build a complete set of three carriages consisting of: 1. A Carriage Base 2. A Carriage Belt Block 3. A Carriage Belt Clamp 4. Three Carriage Bearing Covers 5. Three LM10UU linear bearings 6. Ten M3 lock nuts (nylon insert) 7. Nine M3x12mm cap screws 8. One m3 washer (for belt clamp screw) 9. One M3x40mm endstop screw (you can reuse ones from the original carriages, springs not necessary) Fully assembled, this carriage weighs 131 grams, significantly less than the original metal carriage's 244g. The three linear bearings account for more than half of its mass, at approximately 72g. You can observe these carriages in action here. UPDATE: I strengthened the middle post further to avoid a similar issue. I had previously broken one (due to my own mistake) and found it was weaker than anticipated. To address this, I've made the middle post slightly heavier. Print Settings: Printer: Geeetech Delta G2S Pro Rafts: No Supports: No Resolution: 0.25mm Infill: None Notes: I printed this in ABS using a shell thickness of 2 mm, no support, no infill, and 0.25mm for all layers. I use the CuraEngine slicer, with dimensions sized to accommodate slight (0.2mm) extrusion "outside the lines".
