  1. Due to the nature of my work I can't.

     

    I just tried adding an Ultimaker S5 again and now I have them back (didn't work previously but closed and restarted Cura)

     

    We're trying to use a workflow where they send me their project so I can see the model and Cura settings (similar to what we do with S3D).  This way if their settings are incorrect, I can either make changes...or if it is quicker to use one of Cura's built in profiles, I can use that.

     

    Is that a good process or do you advise another method?

     

    Thanks

    I have done a few things on my S5 so far.

     

    The first thing I did was to replace the UM glass plate with a spring steel print plate by Filafarm (for PLA, PETG, ASA, TPU...). The set came as 4 seperate parts: the spring steel, the print surface sheet, the magnetic sheet and a thinner glas plate. The magnetic sheet with an adhesive side is mounted on the thin glass plate and clamped in the S5 bed sheet metal tabs.  The thin glass plate broke in half a few weeks ago but Filafarm quickly send me a free replacement. They told me this has never happened before.

    Nonetheless the trust in the glass plate was lost. That is why I have replaced the thin glass plate with a nice carbon plate and it looks like this at the moment:

    We installed magnetic spring steel / PEI (Buildtak) sheets from PrintedSolid a while ago.  

    Lately we have great difficulties with Tough PLA sticking to the PEI.  After a few failures we went back to glass.

     

  3. Hi

     

    This one has me stumped.

    My peers send me the Cura Projects so I can open them and see the print settings, model and how everything is set for their print request.

     

    One thing I notice, even if I close out and start new, is the various Profiles are missing.  Such as the 0.1 , etc etc...   How do I get these back?

  4. Hi,

     

    We have two Ultimaker S5's and noticed with active leveling, printing on glass,  the prints are very difficult to release from the bed.

     

    Trying to improve from this, we purchased some magentic bed/spring steel/BuildTak sheets offered by PrintedSolid a while back. 

     

    Due to the COVID thing, I haven't had a chance to try those out until this week (we are allowed back in the laboratory for short shifts for now).

     

    The prints release with that lovely spring steel wiggle but on one printer, you can see the "ghost" of the location where the print was.

     

    My experience with PEI surfaces have been you need to be a tad further away from the bed or the sheet will eventually fail (prints have to be peeled off or eventually rip the PEI sheet).

     

    On my home Marlin-based machines, I know I can Babystep my first layer and adjust it (ideally during the skirt layers of a first layer).

     

    How do others adjust for this?  On the printer?  In Cura?

     

    Thanks! 

  5. Hi there.

     

    I have an Ultimaker S5 and I was hoping to print some multicolor labels to place on some toolboxes and cabinets.

     

    I have found some nice Customizable labels on Thingiverse but those only generate one file.  I do not see a way to make it into two files, as the Cura documentation explains for multi-color prints.

     

    Is there a way to do this within Cura?  To split up the model?

     

    For reference, I was looking at this... https://www.thingiverse.com/thing:2768920

     

    It seems many people pause the print and change the filament [on their single filament printers]

     

    Thank you in advance.

     

  6. Screwhead is inside, thanks for that reminder.  It always makes that un-nerving SNAP when you open the feeder.

     

    I think I have narrowed it down a bit more.  When feeding filament in, it doesn't seem to always hit the hole in the level to glide into the bowden.  It definitely takes some finesse to get through there but it seems like more than usual.

     

    With the cover off, we can see how it should work.  

     

    With the cover on (tension screw under the cover), we tension it to the middle position, per the service manual.

     

    This last time, we loaded PVA and heard a SNAP sound, and it broke the PVA in the tube.  There was a few inch gap between the two segments, so we used the Move process to push them together.

     

    Side note, is there a way for the PVA extruder to do the prime blob as the primary one does at start of print (we checked that on in Cura)  I know we can do a prime tower but that's overkill.

     

  7. I've been working with Erin over to support on this.

     

    To update, I've done some cold pulls on the BB hot end and the first one had a lot of PVA stuck to it.  The second came out clean.

     

    I reloading the PVA and it was trickling out of the hot end.

     

    This morning I had a student start a print with support and nothing is coming out the PVA side.

     

    Still working through some ideas.

    Can you push the filament so far into the Bowden tube that you see about 5cm of it? I always load it that way, then you don't have to wait funtil it comes out of the print core.


    Same here.   But that’s the issue.  Pushing the filament into the extruder isn’t smooth.  There’s something about how it’s connecting to the bowden tube that seems problematic. It can take several shoves to finally get it in there.  But that leads to the failure and grinding 

     

    Only using new PVA that came with it

     

  9. I think one thing I found is the collet piece holding the bowden into the extruder has some play.  So there may be some misalignment there causing friction.  I just put it together again but left a bit of filament in the extruder as a guide to getting the collet/bowden to align/fit right.  I cleaned out some more debris before putting it all back.

     

    More testing

  10. After several months of lobbying, I was able to finally purchase Ultimaker S5 printers for the workplace.

     

    Now, it's one problem after another.  This wasn't the trouble free printing experience I had envisioned.

     

    We received these printers a few weeks ago and just started doing basic test prints, to tech the students.

     

    Printer One keeps having an issue grinding into the PVA material.  Or not feeding at all. 

    We frequently have to manually "move" material for the prints to print with material.  The feeder tension is set to the middle position and I'm still seeing these grinding issues.

     

    Printer Two is even worse.  Feeding filament into extruder two is nearly impossible.  Filament doesn't smoothly pass through.  It takes a few pushes to get it into the Bowden, which just leads to a ground up filament segment if we attempt to move the material or print.  I've had the extruder cover off, referred to the manual and I have 6+ years of experience with Ultimaker UMO/2/2+ printers.  I don't know what's messing up that extruder but it's clean, no debris...and just not right.

     

    I know PVA is tricky and brittle, but no matter how much we change the tensioner, it's grinding and again, that feed from extruder to bowden seems compromised.

     

    I've reached out to Support and hopeful they can offer some advice I haven't thought of.

     

    Have others had issues with their feeders?   I thought I would inquire with the community while awaiting a response.

     

    I spend a lot of effort promoting the ease of use of Ultimaker at work.  Now...I'm pretty red faced.

     

  11. I did a ton of things to my Ultimaker Original but on my personal Ultimaker 2+ and my work Ultimaker S5's...I have left them alone.  Asides some SD card holders and a guide pulley for the filament path of my 2+, they are stock.

     

    I'm printing some Core holders for the S5's I setup last week and perhaps have the students find some novel USB holders to print.

    I agree w the plate in the freezer, takes too long. 

     

    I was able to make tweaks to the UM ABS profile and air manager to:

     

    Make easier to remove

    Get rid of the elephant's foot i was seeing (more of that)

     

    Thanks, please post a link to the plate ypu are getting. 

     

    I did in the first post  🙂
