Custom SV06 Plus X-axis carriage

V4 (Experimental) Now Available

Finalized version of V3, with a few clean-ups. Added tab slots for compatibility with certain fan mods.

I will print this one out and confirm its proper, then this is likely going to be the final version. Work on the Z-blocks is proceeding and will be the next file drop after this one.

This version only needs printed supports for the side caps. The main body is completely free of supports.

V3 (Experimental)

Not yet finalized, needs further testing and printing. It should be a lot better than V1 on several fronts;

• Much-improved printability. Shaped holes and further splitting into separate parts. Almost no overhangs that need support.

• Improved belt teeth geometry and placement.

• Finetunable printhead tilt - especially important for 3D-printed parts, where the printhead tilt is determined by not only the Z blocks but also how precisely placed the heat set inserts were. This becomes an issue for SV06 in particular since the bed probe is offset and any tilt of the printhead results in incorrect measurements. It can now be tuned by turning a bolt, and then locked in by tightening a second bolt. This extra part still fits within the footprint of the original part without interfering with anything, which was not easy to accomplish.

New Z blocks are also being worked on.

X-Axis Carriage

Custom X-axis carriage, takes inspiration from the Monoblock Carriage by @SilencedFros_2044064. Improved to fix some minor annoyances I had with it.

• Uses M3 heat-set inserts (henceforth referred to as HSIs).

• All critical dimensions are within the footprint of the original designs, so mod compatibility should be 100%.

• Flex cuts clamp the bearings in place. If you need a tighter fit you can change it in Blender, but this works great for me. Please leave a comment if you encounter any issues. The model has cuts that function as material stress relief and holes to allow punching out the bearings if need be.

• You will need a decently accurate printer, especially if you're using solid polymer bearings, else the fit might be too tight and increase stick-slip for polymer bearings.

• Improvements over the Monoblock Carriage:

  • Material removed on the back to account for the flex that happens when bearings are inserted; this avoids any rear mounted components (e.g. a fan) from being pushed out of alignment or squeezing the flex cuts.

  • No flimsy small holes and features that break. Uses just the material itself to squeeze the bearings. (Do not print in PLA!)

  • Bearings are kept in place sideways by a separate piece, so that we don't have to go overkill on the clamping force, minimizing friction when used with solid polymer bearings.

  • Requires no special HSIs, just the standard length ones, unlike the Monoblock which requires shorter ones to not interfere with the bearing channels.

Print recommendations:

• Print as oriented. We want precision and strength for the bearing channels.

• Snug supports.

• 15% gyroid infill.

• Vertical perimeters: 5.

• Horizontal perimeters: 5 top, 4 bottom.

• I recommend printing in PETG or similar, PLA will deform when under constant stress.
