WobbleX ball size

Question

WobbleX ball size

Closed this issue a year ago · 5 comments

I ordered 6 WS8kits from the Mellow store and just installed the first set on my Rat Rig 3.1. During the installation I lost one of the ball bearings, I can not find the specs for them, could you include the sizes for each kit? I also left a message for Mellow, it might be a good idea to either include an extra ball or have them as an option.

Same happened to me, I replaced the balls that came with the kit with magnetic ones I had to avoid losing more

Thanks for making me feel better, not being the only one that had lost a ball. I have an assortment on order from Amazon, and will update if I have success.

These are 4mm ball bearings. I was in a hurry so ordered an assortment from Amazon

I would suggest that your order some from AliExpress the same time as you order the WobbleX

Sorry to hear that, yes they are 4mm Steal balls. I have asked Mellow to put extra in the kits.
Thanks for reporting this.

Thanks for the reply! I am sure it was my fault, but I could not figure out a good way to get the WobbleX stack installed in each Z axis arm without balls dropping out. I ordered an assortment that included 50 4mm ball and I think both of my Rat Rigs are now running well.My friend Tim of DWIT3D Canada is going to install on his RatRig in the next week or so, I ordered the same set for him so he will be prepared.I think he will do a live steam of the install. Here is his channel ***@***.***/streams I see a couple of problems, the magnets don't seem to be powerful enough for the stainless steel balls and they are not constrained. I putting everything back into the Z axis printed part it is easy to slightly move the alignment and the balls find freedom. dave wilson 816 792 1060 On Wednesday, May 17, 2023 at 08:58:11 PM CDT, Mirage ***@***.***> wrote: Sorry to hear that, yes they are 4mm Steal balls.
