Solidoodle 4 build platform wobble stabilizer

thingiverse

I notice a lot of wobble from side to side in the build plate as the print head changes direction, and I think it affects the quality of the print. After upgrading my carriages to the Lawsey carriages, I had some extra LM8UU bearings, and also the X and Y guide rods, since I had upgraded to hardened rods for the new carriages. I used one of the bearings and one of the Y Guide rods to stabilize the bed so it could not move from side to side. Working like a champ! Print Settings Printer Brand: Solidoodle Printer: Solidoodle 4 Rafts: No Supports: No Resolution: .3mm Infill: 100% Notes: I use a 20mm brim to keep the part sticking to the plate, should use ABS or PETG, PLA probably won't like the heat. You will need a 14-1/4" 8MM guide rod, I used the one left over from my Lawsy carriage upgrade, and an LM8UU linear bearing, also left over from my upgrade. You will also need 2 x15mm M3 Screws and 2 M3 nuts. Push the screws up through the bottom clamp, put the nuts into the cavities in the top bracket, then loosely attach the clamp to the bracket. Push the rod onto the bottom anchor, snap the LM8UU bearing into the end of the Top Bracket, it should fit tightly and stay in place due to the two inside ridges. Then slide the bearing onto the rod, and cap the other end of the rod with the other anchor. Finally, insert the slots in the two anchors onto the frame of the Solidoodle at an angle, putting the top one closest to the left vertical frame, then sliding the bottom one on from the right. Adjust until they are close to the left vertical frame and as straight as you can get the rod. I just eyeballed it to start. They should be fairly tight, and should not move without a bit of pressure. Slide the bracket up until you can clamp the bracket onto the aluminum build surface support, then tighten the 2 screws. Run the build plate up and down in the Z axis, adjusting the anchors so that the bearing slides freely. If everything is lined up, the bracket should keep the end of the build plate from wobbling back and forth, and should run up and down with no resistance. In the photo I included, you can see I just keep the anchors in place with some tape. Once I am sure of the position I'll drill holes through the anchors and screw them into permanent position. So far it is working like a charm, the build plate is rock solid and moves freely up and down. If you notice the bracket flexing or catching as it moves vertically then you may not have the anchors adjusted right. You can also loosen the clamp to adjust it's position.
