If you appreciate my work and want me to create more, consider donating whatever you can. You can do this by visiting https://www.paypal.me/Blade893 on 13/10/2017. I've added a right slide mount for an 18mm sensor (Cap / Ind) if you're only using one hotend. The X offset from the hotend is +32, and Y is 0. This design requires M3 expanding inserts for assembly and follows version 3.0 of the principle design criteria. Drylin bearings are used, with the left hotend for part production and the right hotend for soluble (PVA) support material. The X rod pitch is 45mm, so ensure this is compatible with your other components (this uses Pursa spacing). When printing, use at least three shells for the bearing block as lateral force on this part is high. Infill should be at least 25% and up to 33% for strong parts. PETG works best at a height of 0.2. Check out the ordinal design at https://www.thingiverse.com/thing:2290564. The printed bearing block saves two-thirds of the X-axis weight and greatly helps with bearing alignment when using Drylin bearings. Fine spacing is achieved by folding cigarette papers around the bearings. Make sure your printer is calibrated in all axes as the tolerances are quite fine. If you're off by just 3%, the bearings will bind if using Drylin, but normal bearings are more forgiving. The extruder mount plate uses standard mounting holes and can be used with pillow bearings found on many 3D printer kits. If you have any questions, message me. By liking this, I'll continue to develop.
