- ghost print in fist layer. Beeps and weirder stuff. my ultimakers hate me :)

Posted (edited) · - ghost print in fist layer. Beeps and weirder stuff. my ultimakers hate me :)

Hi all. My name is Michel from the Netherlands. I sure can use some help. 

Ok. Prepare for the strangest thing everrrr. For me it is like what is at the end of all planets and this.

Ready!?$#  It will get stranger step by step.

Suddenly. Since a month. Problems starting to occur on our ultimakers. We have 2 so that helps excluding causes bit.

At the end of most prints the nozzle stayed on the print and a huge blob appears. So we have to be there when it ends

to save the object printed.   

-Material PLA also  just gets pulled back 10 cm sometimes.

- We have the cannot print out of printing area on some occasions. On very small objecs.

Since a week. And that must have been when i updated to the latest version of cura. 3.5.1  i think. Problems became weirder.
We load a model in cura. And put it on a sdcard. (What works for the last 2 years) And then print that on one of the 2 ultimakers.

It starts perfectly. But then at 75% of the 1st layer it starts printing the first layer of an older print. Of a print that we printed before. WTF.

see the picture below. Like a ghost print. first i thought it where hidden messages :) But later i noticed it is a part of the print printed before.



After many MANY hours of failing. We printed let's say an L on the first ultimaker. And a B on the second.

Then he magicly puts a part of the L in the new B. This moment i started testing EVERYTHING i could think of.

Proof is my messy whiteboard. Full of useless tests. Don't reed it ? its abracadabra. But i tried all i could think.



This moment it had to be within the software itself.  My friend helped me out putting cura fresh on his laptop that never seen a cura.

I let him install 3.1 because that is after googling the most stable version for our ultimakers. He loaded the models that failed here.

And what you know. SOME are printing perfectly. It went to second layer. But got stuck in middle. There it started

printing in the air for a while. Cannot tell what model. Then beeps and goes trough the side. Where the machine gets

stuck and start shaking. What leaves us with nothing. 

At this point when we print anything. the machine ends in shaking horribly. Until a point it gets damaged for sure.

Motor wants to push all trough the glass. Nothing works anymore. As soon as we print like 5 small parts next to

each other it will crash with the last model on its first layer. If it is just one object it prints an older object right trough.


Below the things that we have tried. and excluded as the cause.

- Ultimaker factory reset.
- printing a cube. ( works )
- Printing on old cura V 3.1. ( running now )
- Removing ALL files of cura. Appdata. all single files. And fresh installation of cura 3.1. 
- many different sdcards.
- formated a sd card.
- fix stl programms. But it gets stuck at simple shapes with 20 polygons. (BTW it is not my 3d skill :) )
- Upgrading firmware.. after that a factory reset
- Older firmware. ( Marlin firmware) after that a factory reset
- beer


My final thought. 
We have 2 ultimakers.  1 Um2 extended and 1 Um2.
It is not the 3D model. Although it prints just a cube. Every other simple models fail. And this problem never ever happened for 2 years. 
It is not a broken printer. We have 2. Chances are very low right?. Else the software did it somehow. Almost impossible.
It cannot be the software :S It happens with all vesions of cura. even with a new laptop and new cura. All signals pointed to a

   software related problem. But why the file from my friend does the same. whaaaah.

Then all possible causes are gone. soo Here i am. Does anyone have ANY idea to try? That would be very much appreciated.
Greetings Michel D.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
