Oh., man, "Gunnar".
I'll think, we've discussed this issue a while back.
We just discussed this and you said there is no need for this relay, -only needed in the "wood" versions (for fire protection)..
I'll hope this is the problem, -it will be an easy fix to do. 🙂
Thanks
Cheers

I've come to think about a failure I got on my UM2E+.
Got the same indication as you had in the beginning.
In order to get the printer working, I had to re switch the power switch sometimes several times to have it working..
One day this was not possible, -just as you describe.
Anyway, after some fault tracing I found that the 24 VDC power relay was not working.
So first thing, check that this relay is delivering power to all stepper drivers and to the heaters.
If this one fails, the failure you have will be the same.
I'll think the power supply switching circuits is more or less the same in all PCB versions of UM2 series (except Connect).
Maybe this could be your problem.
Good luck.

Edit: Forgot your random question.
I'm never afraid of this as I have installed two fans (2 * 12) VDC in series, which keep the PCB "cold". But you have a good point there .. 🙂

Does the Z stepper move at all?
I would do a factory reset first.
Also the stepper driver might be the one failed.
If you have the PCB with "the" original five stepper drivers (the extra extruder E2), it might be possible to redict the Z using this "free" E2 driver.
(There is a complete wiring for this UM2 to be used, -as you're familiar with electronics..)
Thanks

Edit: If you measure the voltage at the other side of the R111, you will see the switching voltage for PA7. If this voltage is zero all the time due to a short in the cap, then it is easy. ref: @gr5.
So not needed to pull off the Cap.
Good luck.

Forgot one thing..
I'm assuming (🤔) that the firmware detect "a loss" of this sensor, -and will not continue printing before the error is fixed..
So, even if you deselect it, there is still an error preventing the printer to work.

Hi Eric,
Greg already guided you and sure this will/should (?) be an easy fix.
Here is a link to a site in Sweden, giving details about how to release those small pins.
https://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide
Just roll down a little and you'll find the same type of connector, but here only 2 pin -just the same locking type and series.
Anyway, good luck.

Hi there @kmanstudios,
Sorry to hear about your mishaps.
Let's see a picture(s) where the broken wire is located on this sensor and maybe someone can shear some more info about it. -Even if the wire is broken, -there might be a fix for it.. 🙂
Regards
Torgeir.

Hi @SilverDynamic,
I doubt this is an error due to firmware update, -but this very much looks like a faulty forward fan (the one cooling both nozzle "cold" end).
If this fan stop, due to collected filament stringing blocking the fan or due to an electrical issue.
The heat creep up into the upper tube and softening the filament to early. This issue block/reduce the feeding and will lead to under extrusion that finally may stop all feeding..
This is a known issue.
Good luck
Thanks

Hi @Darkstang5887,
Did you really go through all the thing advised by @gr5 in this tread:

Does anyone know why I am getting this weird effect on my prints? I am using the exact same settings, and same print on a different ultimaker 3 and am not having this issue. It seems like the only thing that could be the issue is something with the printer itself. I've done almost every calibration, bed level, swapped printcores, checked to see if the fans are working. The temp was at 200 C for PLA which is what I use for the other U3 printers. It looks almost like the PLA "rises" and then the nozzle pushes it down, and squishes it over and over. It just looks fluffy. Again, I have the same exact cura settings on another U3 and it comes out perfectly fine.
Hi @UALib3D
You've already got good advice from @gr5 here, -so I'll just add something more..
This is quite interesting, first I noticed the brownish color on the front (inlet side of cooling fan) that tell a story?
This color indicate high temperature, a black debris just in front of the printed object and finally the nozzle in the middle of the print. All this indicate too high temperature to me. How does your print head look from below?
So, -inside the head there is a control PCB (printed circuit board)and this board also include the precision amplifiers for both print cores.
Say that no1 print core amplifier by some reason say that the temperature is to low, then the control circuit will increase the temperature as high the error signal tell.
If this is the problem, it would not help to change (swap) the print cores.
You may also use an infra red temperature sensor in order to check if the temperature is correct.
A better close up of "all" sides of your model may give more info about the problem.
Also try to turn the model 45 deg to see how this work..
Good Luck
Thanks

It's easy to press a key - sometimes...
Way to go Greg..

Hi @Reddley
Great Readdley.
Maybe you should try the "new" version of Cura, the Cura Arachne Beta, still an experimental version -but this version handle the layer width much better.
There is some issues with it, but think it will work well for your model and give you some good prints..
You can use your project file from Cura 4.11.0 and see how it goes in Cura Arachne Beta.
You'll find it here:
Good luck.
Thanks

Hi @Reddley
Well, -it just was the function (under walls), "Fill Gaps Between Walls" that was enabled and made all this extra wall infill.
Just changed this from "Everywhere" to "Nowhere" and then the infill become normal..
(I've never been using this function.)
Hopefully, this was the problem.
Thanks

Ok., just loaded your model into Cura (4.11.0) and used my printer (an UM2E+) with default setting "Normal 0.15 mm".
With this default setting the model comes out fine with normal infill and top/bottom as it should be..
So this problem seems (to me) to be some setting "confusing" Cura.
I'll try to tweak a little around with your profile, may take some time..
Thanks

Hi @Reddley
This was weird, looks like the infill in the wall is mixed with a solid layer (top or bottom?).
1) When the walls are printed it start with outer and inner walls layers then infill are done normally and a new layer start.
2) The outer and inner walls starts as above, but instead of continue with infill -it start a top (or bottom) layer.
3) The outer and inner walls starts as above, this time normal infill -and continues on like this every other layer.
Hmm, have to say that I've sever seen this before -just wondering if this is a new function in Cura -or is it a bug?
Hi @GregValiant, can you share some light in here?

Aha, I'll see you have an Ender CR3-Pro -so I'll think this is a question for @GregValiant
Greg knows all about this printer and much more.. 🙂
Thanks

A better way is to go to "file" menu in Cura then select save project file, this will save your model as; "Buck Converter Box.3mf". This file will hold your model with all setting selected in cura plus your printer info, this way we'll see exactly the same as you're seeing your model.
Thanks

Hi @Reddley
Welcome in here.
The only picture that's some strange looking is the first one, -as you can see some of the infill in the top mixed with yellow (infill is amber colored)..
You'll need to save your model as a "project" file here, then someone can have a look in order to help you.
Thanks

By the way, I'm not sure what version of Cura that's used here, but I'm using ver 4.11.0 at the moment and there's some changes..
Thanks

Well, since the two walls are red, I assumed it's a solid block.
-
Is not this because of the selected wall thickness is 1 mm and using a 0.4 mm nozzle the problem here?
I would try to select wall to 0.4 mm and do another view..

Hi there,
Prime Blob is found in Cura under "Build Plate Adhesion".
It's normally hidden, but go to Preference then select "Cura Settings" and next press settings.
Write "Prime Blob" in the search window.
Here you'll see that "Prime Blob" is selected by default, so just deselect it here.
Thanks

Hi there.
Don't we forget an important "detail" here, -that we're also using carbon fiber rods along the entire wing, and that this is also used in the tail section and the rest of the hull (air frame) -when necessary.
This reinforces the entire "aircraft" and maintains the needed flexibility.
Also, a horizontal printed wing will be stronger, -but suffer for the aerodynamic shape..
Just some thoughts.

Hi @CalvinCR
If there is any 3D printer there is worthy to repair, -it's for sure an UM2E+!
So let's see the pictures of the damages and also a picture of the mother board.
There's just four 8mm shafts and two 6mm shafts to change. But those shafts can take many thousands of work hour before any need to change.
Shafts pulleys and belts is standard parts in the robot industries -so it is easy to find.
How many hours have this printer been printing?
Thanks
