My prints come out very well but I’m noticing on larger prints that one corner of my bed prints tighter than the opposite. What’s causing this?

Printing on an Ender 3 Pro with upgraded metal extruder, beefier bed springs and metal levelers, and upgraded hot end. Not direct drive yet and no auto bed leveling.

    The soft bed on my old ender 5 had a noticeable wave to it. Levelling it was kind of a compromise. A few areas would end up with more squish than others.

    Actually no bed can ever be absolutely ideally flat and level. As long as you get close enough, it’ll be fine. Print smaller parts on the best area if you can.

    But, like others have said, matrix leveling helps a lot. Which pretty much means getting a levelling sensor.

      The print came out great so it wasn’t really an issue. Just more of an exercise than anything else. I am looking at getting a CR Touch. Not quite ready to convince my wife to get a vastly faster printer (and I’m not interesting in investing a lot more time to upgrade the E3Pro to Klipper). I’d rather throw money at the slowness problem and solve a lot more issues at the same time like direct drive, multi color, etc. in future. She’s gotten one functional print she loves out of this one so far so the pump is being primed so to speak.

      Thanks for the matrix advice!

    If one corner is tighter that would seem to indicate a heigh spot on ur bed hence the extrusion is being squished into a thinner layer

    Probably an unlevel bed, it’s thinner there because the bed is higher.

    I highly recommend a CR touch add on for ender 3s, probably the best upgrade I ever made. Not only will it fix stuff like this, but it will also let you plug the printer into your computer and you can use octoprint to render a 3d depth map of your bed which makes bed levelling super easy.

      100% agree on the bed level sensor. I have a BL touch and it is far and away the best upgrade for my ender 3v2.

      I’d definitely recommend anyone adding a touch sensor play around with different firmwares. I was running a very buggy firmware for about 2 years and didn’t realize I could just find something that works better. My new firmware works so much better and has so many more features, all in a $0 upgrade.

        As someone who’s currently upgrading his setup, I’ve had no luck so far with firmware.

        Can you point to some resources? I’m still a novice and I’m sure I’m not the only one. I’ve done some DDG searching and turned up some hot garbage, maybe I’m looking in all the wrong places?

          I had the same issue myself when I added my bltouch to my CR-10v2. Maybe check YouTube videos for GitHub links? I used the 3dprinting Canada video which had a link to a firmware build that worked.

          Sorry, I’m not able to access my PC for a while so I can’t look. All I did was google something like ender 3v2 bl touch firmware and went from there.

    Had a similar issue with my Ender 3 Pro. In my case, turned out the bed wobbled. A quick Google search said that it’s apparently a pretty common problem with Ender 3 Pro’s. I had to tighten the wheels that held the bed in place, and that completely resolved my problem.

    So, my advice would be to check if your bed wobbles

    Check to make sure your carriages are tight to the rails, both for the extruder and for the gantry. On the ender 3 pro there’s 2 wheels on one side and one wheel on the other, the one wheel is attached via a hex shaft that’s off center and by spinning that you can tighten/loosen the wheel to the rail. Mine were loose and it was resulting in something similar to this

    Your whole model needs more squish, but that corner a bit more than the rest. There shouldnt be gaps visible between lines

        When I say more squish, I mean get your nozzle closer to the print bed or increase extrusion rate. Gaps between print lines are visible and they shouldnt be.

        Sorry if I was unclear, I was even surprised I got downvote LOL

    Do you have any kind of ABL (BLtouch, etc?). If so what does the bed mesh look like.

    Regardless it may be worth looking at leveling (tramming) your bed.

      It was leveled pre-printing and with a heated bed. Could still be a level issue because I don’t have ABL but I’m not a noice to leveling.

      Print came out great regardless. Also, not my model.

            Ahh. May be physical then. I do have a longer write up I did for somebody else who was having issues who was running Klipper I can link to shortly.

            But basically it may be worth making sure everything is solid physically. E.g. extrusions are square, not overly tightened, vwheels are tight enough without being so tight that they end up having bumps and presenting weird issues like this.

            Here’s the link. Nothing more frustrating than when everything should work and just isn’t. Been there so many times myself.
