Zonestar P802qr2 motor mount Z axis

thingiverse

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/1lsOqybtPPp I took Simhopp's Replacement Motor Mount, and I adjusted it for Zonestar p802qr2 metal. I took Adjustable Z-Axis Motor Mount by djnicolosi3148,and I adjusted it for Zonestar p802qr2 metal. I took Anet A8 motor mount fix by klownius,and I adjusted it for Zonestar p802qr2. Also, A big thanks to Simhopp, djnicolosi3148, klownius for doing this! I printed this using ABS and 40% infill .14 HOURS PRINTING TIME. Klownius took Simhopp's Replacement Motor Mount, and adjusted it so that it has slotted (oval) screw holes for the four motor screws. Also, I adjusted the motor hole so that it is also slotted (oval). Each Z Axis motor can be slid to the left or right. This should straighten up those threaded rods and allow the Z carriages to slide up and down smoothly. Now, it is possible to reprint the carriages on either side so that they straighten up the Z threaded rod, too. They can still be used with this mod to tweak it just right. And replacing that fragile acrylic is always a good thing (I keep mine as spares). Klownius measured the center of the threaded rod to the center of the non threaded rod on each side. I now have 23mm on top and bottom for BOTH sides, so I know they are pretty parallel. (They can bear weight if tilting the printer). I pounded the top plate onto each side plate with a rubber mallet, and I screwed them together (tight parts fit = no vibration). Then, each mount box slid right into the frame, no issue, no mallet, no anything. It is an easy replacement, but it took a little bit of fiddling to get the axis perfect straight. Also, I installed a cork gasket over each motor to help with vibration. Each mount was three separate pieces (rather than one single piece), and this was done for two reasons: 1) Strength of materials - long thin layers on the side walls are more brittle than a large layered area. 2) If your Z Axis is really bad BUT at least can print under about 10mm (probably closer to 8mm), you can print this (still need good X and Y axis). Work in progress . It's on my ZONESTAR P802QR2 right now.
