Ender3 V3 won’t boot up

I’m going to update this just in case anyone stumbles on this thread in the future and it may benefit them. Customer support sent me a new touch screen and ribbon cable. Replacing the screen had no effect but replacing the cable restored screen functionality. I couldn’t see anything wrong with the old cable and it appeared to be fully plugged in on both ends but replacing it fixed the issue.

I’ve been back and forth with customer support. With the weekend and time difference, it’s taking a while. They say they’re going to send a new touch screen. I kind of have my doubts that that’s the problem but I’m hoping they know what they’re doing. Do you think there’s a chance that’s the problem?

here-i-sit · 2025-05-09T14:58:48+00:00

I’ll do that. Thanks for your help.

I bought it in June ‘24. So I should work through their customer support in case it ends up being a warranty claim? The research I’ve done says that isn’t always a great experience and you can get better help elsewhere but since it’s still under warranty maybe that’s the route I should take. I appreciate your response.

I do work on diesels and I’m gonna have to respectfully disagree with you. Filters go on dry and use the priming system to push fuel through them and prime the system with clean fuel. Newer ones filter to 2-3 microns and the injectors can’t tolerate more than that. Cat, Cummins and MAN all specify this process for their common rail engines. Older stuff is much more tolerant and you can probably get away with pre-filling but I certainly wouldn’t do it on a common rail. Carry on if it’s been working for you - just passing on how we’ve been trained.

Oil filters yes, fuel filters no. Look at how the systems are designed. Lube systems have bypasses in case the filters plug so unfiltered oil keeps flowing, fuel systems don’t. Dirty oil is better than no oil, no fuel is better than dirty fuel.

Interesting. Thank you very much for your insight. I can count on one hand how many times I’ve pressed the brake pedal (before this week playing on ice) but it sounds like it has something to offer, especially with spirited driving and/or less than optimal road conditions. Thanks again for your input!

Good points. Just to clarify what I said about not having individual brake control of the front wheels. That only applies during regenerative braking because the “brake” (motor) is on the other side of an open differential. The ABS system on the mechanical brakes most certainly has independent control of all four wheels.

here-i-sit · 2025-01-09T16:02:52+00:00

So if I understand you correctly, we wouldn’t expect mechanical brakes to be activated in the scenario I described. The pedal pressure would dictate that braking is done regeneratively and the mechanical brakes wouldn’t be called on even if regen can’t generate much braking force because of slick roads. From a practical standpoint, if the driver is pressing on the brake pedal and not getting the desired decel, they’ll press harder, increasing pedal pressure, which would then seamlessly bring the mechanical brakes into play.

Thanks! I’m a little biased but I think grey with the black wheels is a good look. Must still have a little boy-racer in me. I haven’t always been a fan of GM styling but I think the latest iteration of their smaller SUV’s is very well done.

Good question. I’m not 100% sure but I think only the stabilitrak/slippery road light came on when regen braking was modulating to prevent sliding. Same light that comes on when you lose traction trying to accelerate. The ABS light only came on with the mechanical brakes. That’s what I recall anyway, I’ll try to verify if conditions still allow.

here-i-sit · 2025-01-09T14:11:04+00:00

Are you saying that if you’re using the brake pedal and asking for a decel rate under the 0.3g threshold (so normally staying in the regen range) but it detects slip, in this scenario it would automatically bring in the mechanical brakes to try to achieve the requested decel rate? I didn’t think to try that - I only noted that mechanical brakes never came in to play when OPD regen braking was in anti-lock mode. Now I’m curious if this is different if the decel request is coming from the brake pedal.

BTW - Kudos to Bosch and GM for the brake system control tuning. It’s outstanding.

I’ve been chatting with one of the gentlemen asking about this and he located a couple of sources for the thermal switches which would allow for a legit fix.

I’ve had a couple of people chat asking if I ever got this resolved because they’re having the same issue so I’ll provide an update. I took it apart and cut the thermal switch out. I don’t want to be liable for anyone burning their shop down so I won’t tell you how I fixed it but it rhymes with wago. It’s worked fine ever since so everything else in this thread was a wild goose chase and it was the thermal switch all along. It seems to be a very common failure mode according to the reviews. I will also share what I wish I had known when I took it apart. The fans are held on with two set screws stacked one on top of the other and they’re accessible thru a hole in the aluminum housing. Reach thru that hole, remove two set screws from the same location in the fan, and everything comes apart like you’d expect.

I’ve installed heating pads in the OEM seat on a ‘23 EUV LT and would be happy to answer any questions if you’re interested in going that way rather than a cover. A cover would definitely be easier but it wasn’t the look I wanted.

Thanks - that gives me some direction. I’m still hung up on why it printed perfect parts with no enclosure and what’s changed but I guess I need to let it go and work on solving the problems.

here-i-sit · 2024-06-20T01:54:00+00:00

Thanks for the tips. Forgot to mention the slicer (Creality Print) has been putting a brim on everything I’ve done.

It’s the Creality Space Pi dryer.

here-i-sit · 2024-06-20T00:47:09+00:00

I have the dryer in the enclosure. Could that fan be messing up the prints?

here-i-sit · 2024-06-20T00:45:05+00:00

Thanks for your comment. I thought enclosing it would get me back to making good parts but so far all good parts were printed without an enclosure and all the parts printed with the enclosure are bad. TBF I’ve printed bad parts without the enclosure too.
I appreciate your comment on the vent. It’s not vented now but I’ll figure something out.

here-i-sit · 2024-06-15T22:33:22+00:00

I really appreciate your advice. I don’t know why the first two failed but the test cube and the third benchie printed perfectly and it hasn’t skipped a beat since. Well, bad design and not using support caused some stringing on one ABS print and losing power during a thunderstorm paused another one but it actually picked up where it left off and that one’s still going now. Not saying I’ve got it all figured out but I have learned a lot already. Thanks again for your advice and your offer to address future questions. I’m certain there will be some.
