Hi all,

What is the best way to re-align the wanhao duplicator i3 plus y axis without being able to 3d print a tool for it? The tutorial I found on youtube is for the non plus model where the electronics are housed outside of the frame.

I noticed the print quality was getting worse and the y axis sounded funny. I checked and found that the screws were loose for the y axis rods so I printed 2192046 from thingiverse and attempted to realign it.

Now my bed will not level at all, I can get 3 but not 4 corners right and I can not print at all. If I print a square, the right side will be 0.3mm wider than the left side and it immediately lifts off the print bed and sticks to the nozzle once it does anything within the square. Before leveling was no problem.

Thanks!

Best way is to slightly loosen the Y bearing screws and then while pressing down on the bed, move the plate from front to back a few times to align the bearings. Do not let go, slightly tighten a few of the bearing block screws and move back and forth again while contributing to tighten.

If you heard crunching bearing noises then some of the bearings may be going bad.

Thanks for the reply. I have attempted that but it seems one rod is slightly higher than the other (in the Z direction) because no matter how many times I try, one corner of the bed seems higher than the other. I have tried using both the upgraded aluminum plate and the stock plate.

I did manage to contact wanhao and they gave me instructions for the V2.1 to loosen the screwed on the front of the printer that hold the metal plates together and to press the printer onto a hard surface to align the frame. I have not tried it yet.

ifits not the bearings that are crumbling, which it normally is,( get some more ball bearing type or thre the new plastic printed slides) then start to level the bed from the beginning. it may be that the bed is that far out of level that no amount of compensation will work. this also has the effect that x and y values can be printed out of wack. Start with a level playing field :slight_smile: . What are you standing the machine on? Buy a cheap level and make sure the surface is near level. once done stand machine on it. loosen y rod end screws, moving table out of way place level on y rods front and back. tighten when level. assuming you have checked bearings, go to bed adjusters and try and level bed in middle of their adjustment, at same time checking both z axis limit switch for firing when bottoming out and preset Z axis origin limit. if you don’t have a depth checker then you will have to run the g code consul to check. you may be surprised that you are totally missing the z axis stops now. That’s how far your base level was out. These machines are made to compensate for minor variances only,they will settle and they will run out.
