Answer to: Z-Axis screws are not perfectly vertical and cause rattle/ vibrationsI checked the seating of the smooth rods on the x-axis, there were ok, they are all the way in. But I think I found the reason for the rattling sound of the z-axis lead rods at the top holders: the distances of both (z-axis) lead screw/ smooth rods is not constant. If i measure at the bottom, right next to the stepper motors, the distance is 2.52cm (B in the pic below). But the distance just above the x-axis holder is almost 1mm wider (A in the pic below). When the x-axis is all the way at the bottom, both lead screws are therefor pushed to the center. With heavy x-axis movement, the z-axis lead screws then touch the inner perimeter of the top holders and create the rattling. Am I the only one where the distance between the z-axis lead screw and the smooth rod is not all the same when measured above the x-axis and above the z-axis motor? Printing the z-axis top holders with wider inner diameters (of the lead screw cavity) may solve the annoying rattling/ vibrations but why is the z-axis smooth rod and the lea...
Answer to: Z-Axis screws are not perfectly vertical and cause rattle/ vibrationsThanks for your replies! I checked several times if the screws are equally tightened and I even tried to tighten them differently to improve the misalignment of the rods. That had no success. I will check iloosion's remark about the x-axis smooth rods beeing not pushed in all the way. That didn't come to my mind yet and makes perfect sense. Thanks for the hint! I will report back as soon as I could check..
Answer to: X axis assembly issueIf I look at your 4th picture it seems you have inserted the linear bearings from the wrong side or you pushed them in from the correct side but the first one in too far. Did you do Step 3 of the manual as described? '''Insert LM8UU linear bearings into the printed parts (X-end-motor and X-end-idler) as shown in the picture. DON'T TRY TO PUSH the bearings from the other side. There is a rim (smaller diameter of the hole)."'' 3. X-axis assembly
