Print Head Cover won't close

Recommended Posts

Setting up our new 3 extended and can't get the printhead cover to close. The printhead cover was taped shut when we unboxed. We removed the tape to put in the BB printhead and the cover won't close. Tried to close it without the printheads installed, and it still won't close. The magnets appear to be spaced too far from the bolts.

Advice?

That's a good question. I see that slideblocks are black. The shaft should be inside the block. Move it yo a corner to avoid torsion onthe shafts and click it in.

The magnets look (I could be wrong) a bit out, mines are more 'in' and not glued, but my um3 is beta. I would drop a mail to the reseller asap with photos or this post link.

I was able to push the shaft back into the sideblock.  

The magnets are pushed all the way back into their plastic holders so I don't think they are extending out too far.  The magnets work and other magnets stick to the bolts, but even when I take both printheads out and press the cover closed and see that they are touching the bolts, they don't stick.  The cover itself is flexing like a spring and pushes the magnets away from the bolts when I let go.

@ASL_MILL I know is a silly question but have you check if there's anything between the fan/plastic area there? Is weird. Try to take out the cores and see if closes? (thinking outloud)

Can you make a video? I don't see anything different than my um3 that could do that.

Also afaik all printers are used to print once before shipping it (there's a print cube on the foam made with your printer, probably in silver/black pla).

Several testprints are made with every printer that leaves the factory, and one of them is in your styrofoam packaging (dual color piece).

The metal shaft is supposed to be clicked in the black sliderblock. Feel free to click it in.

Seems to me your printer had a rough ride on its way to you. How did the box look like?

How much do you want to do yourself to get the printer running? I have some tips for you. The front fan bracket should be hinged on the back of the printhead. Is the bracket attached to the hinge points?

Secondly, the front fan bracket may be bent a little. See this illustration.

You may carefully bend your bracket slightly to get it to click right.

Of course, you have every right to not do this and ask your reseller for support. You paid for a premium product, and I'm sorry to hear it did not arrive right.

Hi Folks,

Very interesting. I would remove both cores and investigate closely inside with a good flash light. If you just hold the cover lightly toward the position where it stop, you might be able to see the problem here. Also, as there is a fan inside the cover, -is this one installed right? Study the hinges to see there is no "sudden stop/hard stop" that's preventing a free swing in.

Maybe the taped cover is just used as a transport protection.

Well, just my 5 p.

Good luck.

Thanks.

Torgeir.

Good news! After some bending and twisting of the front fan bracket, I closes and stays in place as the printhead moves around. Thank you for the advice tomnagel.

The bad news is that I can't get it to print anything. I completed the setup steps and loaded a print onto the USB, but it just keeps telling me that "the difference between the height of the printcores exceeds realistic values."
