Hi I have a question about mounting a wheel between two plates and the eccentric spacers adjustments. A similar question had been asked by kylesmth here : Tips for back to back plates on vertical gantry Rick 2.0 had mentioned the problem of the orientation of the eccentric spacers for the adjustments. This case can also be found on the X-axis of Voxel which uses 2 eccentric spacers. Voxel OX - Extendable 3D Printer and CNC Platform I'm actually remixing this very model. In my case, for practical reasons, both plates of the X-axis will be 3D printed so I have a choice in my own design not to have the same plates on both sides and choose the diameter of the holes. My questions are : Is it better to have 2 eccentric spacers on both sides of the wheel between 2 plates ? Or to have a single eccentric screw on one side and a aluminium spacer on the other ? I'm wondering how it would behave in the two cases. Thank you, Pierre
Better to have a rigid (non-eccentric) on the main load bearing side. if you have eccentrics both sides you can set things up skewed - a reference plane is a much better idea. Hope that makes sense? Alex.
Dear Alex, You reply totally makes sense ! Thank you very much. I wasn't sure with those 2 eccentric spacers and you've confirmed my fears not to do it. Yes, the Openbuid team already told me to take inspiration on machine bundles that already exist in the part store. I'm not doing this conception in a rush and take my time. Bonnes vacances (if you're on holidays). Pierre
