Flsun QQS Ball Mount Effector

This is my version of the Flsun SR effector and rods for the QQS. It improves accuracy, reduces noise, and can improve speed.

This design is for the use of 10mm ball stud that are threaded with 4mm threads. I used 60mm long full thread bolts cut down to approximately 54mm long for the effector, and used 4mm x 12mm bolts for the slide.

The slides are designed for long series LM8LUU linear bearings. I used these https://www.amazon.ca/gp/product/B083XQTH41/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

But this will be up to you.

I would refrain from using 2 shorts bearing stacked, I tried this and has alignment issues, so a single 45mm long bearing is best.

For the balls, I used https://www.amazon.ca/gp/product/B07HQ72H1R/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
and work great.

For the Arms, I used 1/4" aluminum tubes I purchased from a local hobby store. I cut to a length of 255mm and glued one end on and let cure, I used 2 part 5 minute epoxy. once cured I used the fixture to set the lengths, do one at a time and the overall length is critical, only use one fixture to make all 6. this should make 285mm rods. But measure the best you can for yours and use that for your settings.

For the effector, I used PETG-Carbon fiber, as I found this material hold up to the heat, as well is extremely stable dimmensionally.

The rod ends can be made from PETG, Nylon, PLA, printer must be pretty well calibrated as the diameter for the ball cup is tight and may even still require some work to get them a perfect fit. I used PETG for mine. And I took a spare ball and used a grinder to cut a slot in it, then mounted in an electric drill to shave the inside of the cup, the fit needs to be perfect, and no resistance to move the ball once installed.

Once you have all printed and installed. Perform calibration and enjoy.
