I’m assembling an out-of-box 2019 Shapeoko 3 XL(standard z axis), it came with upgraded X and Y steel belts. When the gantry is pushed all the way to the back of the Y rails (by hand), the belt idlers encounter a large resistance when they meet the area of belt doubling about 2" of final travel.
I see a post by jjohnson sep '20: Idlers Tight with Belt, had same issue. The workaround was to reduce the belt doubling length to 1" to avoid the issue.
- Are the steel belts thicker than the standard belts?
Has the reduced belt lap length introduced any problems?
Thanks,
Scott
