First Layers problems (thin, not stick, etc) - Tried several solutions without success.


Recommended Posts

Posted (edited) · First Layers problems (thin, not stick, etc) - Tried several solutions without success.

Hello guys, you probably heard about this problem, pleasee see picture:

As you can see the first layers are very thin and unstick.

2015-08-06-2005.thumb.jpg.fd61af74b8857da5a5afcd212a2ccdcf.jpg

I tried:

-Print a default part (A part with CURA setting that used to print perfect)

-Clean the bedplate.

-Adjust the bedplate (many times with many techniques)

-Clean the nozzle (Athomic Bob, and I also dissassembled the whole thing and put the nozzle into a oven at 400 *C - I can see light through the nozzle)

-Tried with different filament (Original Ultimaker PLA and GlowFill Colorfabb)

Points to consider:

1-I used to have this problem, but I solved it adjusting the bedplate + Athomic Bob.

2-The problem is worst and more likely with Glowfill PLA than others.

3-My nozzle is a bit flattener (because of Glowfill abrasive nature).

Tomorrow I will Try:

-Try with a complete new filament.

-Repleace the nozzle kit.

Any advice will be apreciated.

Kind regards.

EDIT:

SOLVED THE PROBLEM repleacing the PTFE insulator and NOZZLE.

I also adjusted the height bethween the PTFE and Isolator in 1mm.

Now is printing like the first day, I will try to find the Olsson Block, I would like to try the colorfabb XT which according to the supplier is also abrasive.

Regards

    What did you clean the bed with? Make sure you use achohol and don't touch the glass.

    Is you temp to low. If it's not hot enough it acts like a gewy rubber band and pulls off.

    Check initial layer height. Make sure it's not to low or high. 0.3 is default

    Check to see if you feeder is slipping.

    I think your point 3 is very important and might be the main reason for your issue. I recommend a replacement with an Olsson Block. Then you might consider the usage of a stainless steel nozzle for the glowfil filament. And, as @labern pointed out, make sure the bed surface is clean.

    You can also print on a cold table PLA and similar materials.

    The first layer need not be perfectly adhere to the table and does not need to be closed door.

    Simply use glue to 3D printing PROGLU3D PLA-cold, the adhesive solves most of the problems of deflection, warping and detachment a printout from the table.

    Of course you need to level the table and improve print settings but you do not have a heated table and really save money.

    You can also print on a cold table PLA and similar materials.

    The first layer need not be perfectly adhere to the table and does not need to be closed door.

    See this picture, these are prints of 50 hours or more without heating the table and printing is constantly on the spot.

      • 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 5.3.0-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.
