3d printed X-Axis stiffener for older models

[eried]

I have a 2016 X-Carve and this is my solution for stiffening the X-Axis:

X-Carve X rail stiffener to reduce chatter by eried

Each pair is composed of 2 plastic pieces, 1 screw, 2 washers and 1 thread insert (check the link up for the dimentions details):

Of course, there is the 30 minute mod:

My feed rates were limited by chatter with the stock 300W spindle. I just upgraded to an 800W GMT spindle and wanted to stiffen the x-rail at the same time. I inserted M5 50mm hex cap bolts vertically in the gap between the x-axis maker slides. They are a perfect fit for the gap. I used 5 bolts spaced about every 6.25".

And the 60 minute mod:

I really liked the idea of not having to drill holes through the maker slide on the 30 minute x-axis mod (https://discuss.inventables.com/t/a-30-minute-x-axis-mod-to-reduce-chatter) but thought I could take it to the next level. Rather than using washers to clamp the two rails together, I took a trip to the corner hardware store and picked up two pieces of flat bar aluminum. One piece measuring 1”x1/8”x48” and the second one measuring 3/4”x1/8”x48" [image] I cut the length of both bars to ma…

I personally think my solution is superior because:

1. It enforces a precise distance between the 2 rails
2. Holds the rails using the shape of the rail itself
3. Is very lightweight (13g in plastic per pair)
4. It is completelly removable, does not even leave scratches or marks on the rails

In any case, after just fitting 1 piece, without even using screws I can see how the flex is completely gone.
