Wobbly/lopsided UM2 Frame

Posted · Wobbly/lopsided UM2 Frame

Hi all,

When I bought my UM2 back in February, I noticed that the front left corner didn't touch the table that I'd put it on, but I assumed the table surface wasn't flat and thought nothing of it.

Recently though I moved it onto a surface that I know IS flat, and can see now that the frame itself definitely is lopsided - the FL corner is about 5mm off the ground.

A bit of context: As well as other under-extrusion related problems I've had with this printer, I've never been able to achieve a good level - the back left corner of the bed always seems to be a bit higher than the rest, meaning that first layers don't show up there, the head being too close to the bed (or they do but are far too high everywhere else, depending on how I level it).

Are the two related, and is there a way that I can fix this - would it be viable to somehow loosen all of the screws and re-tighten them with the frame properly built?

Best, Damon

    Although I have a UMO, I think the construction is similar. I've also read about people doing exactly what you suggested...loosen all of the frame screws off, press down from the top to square things up and get it level, then retighten everything. Simples!

    Ok, I'll try that!

    You mean the frame or the bed? I wasn't quite sure about what part you refer to.

    If it's the bed check this post:

    If it's the frame I would contact your reseller since the bed leveling depends on the frame as the assembly manual suggest:

    As you say, I think it's likely that the frame is causing the level not to work.

    But is there anything that the reseller could do seeing that I've had it for 9 months now?

    Well don't know. worth to try? Check that post about the bed since it might just be a bad screw. About the frame I really have no idea. But I bet there's someone that can drop good advice about that.

    Ok I have emailed Dream3D and am awaiting a response, hopefully they will be able to do something, seeing that it is still under warranty.

    I have checked the buildplate and no screws are sticking up but thanks for the suggestion. :)

    Hi Damfal003

    I have noticed similar issue with my Ultimaker 2. Would you please let me know if you managed to reduce the gap? Is it sitting flat on the table now? mine has about 3mm gap in front left corner.

    Kind Regards

    I have the fuzzy memory of someone else having a warped frame (one foot not touching) on a UM2 maybe a year ago. Maybe it was @Titus or @NicoLinux, not sure.

    As I recall what he did was to loosen all/several the frame screws just slightly, then press all the top corners down so all feet touch the ground, then re-tighten all the screws. The ground needed to be really level though.

    Anyway, this is just a fuzzy memory and my details might be wrong. But a bit of searching for warped frame or something might lead to help.

    Also, if your printer is still new enough, the contacting your reseller is probably the smarter first step.

    Anyway, hope it helps. Good luck!

    Wasn't me

    Plan sounds legit though, but if it's a new one contact your reseller indeed.

    I did this to my printer. Loosened really all screws touching the frame and pushed everything down and in shape.
