Tronxy P802MA Anti Z Wobble Upgrade

myminifactory

I designed this based off of my Tronxy P802MA printer and can confidently assure others that it will work for them as well. A crucial piece is included for both the left and right side, so be certain to pay close attention when adding them. Each piece measures 10mm in height and securely holds a single 608 bearing in place. The fit is precise, requiring you to press or hammer the bearing firmly into position. The Z wobble upgrade attaches to the 8mm guide rod, the 8mm lead screw, and the 3mm screw that secures the guide rod's top piece. Each of these holes' centers are 17mm apart, creating an equilateral triangle that fits my printer perfectly but can be modified using the Tinkercad file if yours differs.https://www.tinkercad.com/things/7IeIgmBBuYe To install: Press the bearings firmly into the Z wobble upgrade pieces until they are flush with the top. Remove the two screws on each side that hold the top pieces in place. Carefully lift each piece up enough to pull the lead screw and guide rods free. Gently press the bearing-bearing side over the lead screw to test for a snug fit. If it's too tight, use sandpaper wrapped around a smaller tube like a screwdriver shaft to smooth out the inside of the bearing. I only needed to gently sand for less than a minute with 320 grit paper. There are left and right pieces! Once the fit is perfect, press the upgrade part over the guide rod and lead screw. You may need to wiggle it slightly to get it to slide down properly. Ensure that you press it down far enough so that the guide rod and lead screw can easily fit back into the top piece. Tighten the screws that hold the top pieces in place, replacing the piece that holds the guide rod as you go and inserting the screw. The upgrade piece should be able to securely hold this screw without a nut. Be cautious not to strip it by over-tightening.
