Hey, so I am currently assembling my XL Shapeoko 3, and while I am new to at-home-CNCs, I am fairly mechanically inclined, so I have a general understanding with what I am doing, but I am struggling to accurately tension one of the wheels to the V of the rail (I was able to successfully tension the other wheels).
The wheel seems very tight so that it does not want to rotate regardless of the position of the eccentric. I have loosened the screw portion relative to the eccentric nut, and while this has provided some freedom for the wheel to rotate, I am having a tough time tensioning it properly. The closest I have gotten allows the wheel to rotate when the carriage is moved (relatively) quickly, but continues to slide when the carriage is moved slowly. Further, none of the other screws seem loose at all and I’m concerned I am affecting the spacing by loosening the screw. I may be attacking this in the wrong way.
I have tried untensioning the other eccentrics, but that hasn’t helped.
I can provide additional information as needed.
