UM S5 grill mod to prevent blocked front fan

Posted · UM S5 grill mod to prevent blocked front fan

hi guys

first clogged nozzle on my UM S5...

Over a +48h Print, the front fan pulled in that many fine PVA hairs. Up to the point that the fan stopped rotating and the space behind was filled with plastic hair.

The now uncooled cold-end of my 1st AA core of course clogged soon afterwards.
lucky that the S5 noticed the stopped filament and printing halted.

 

So, i found the factory front fan grill unsuitable for filtering the debris eventually produced in the UM.

I will put in this as quick fix:

Fine stretch mesh. Got it from an Architecture model builder materials shop.

    Were you able to save the print?

    I had the same problem with my Ender.  I call it "cotton candy" and it's so fine I haven't been able to measure it.  Heck, sometimes it's so fine it slips between my fingerprints and I can't grab it.

    I tried a grill but it needed to be cleaned or the same problem arose (lack of air).  I decided to move the air intake to the side but it still picked up the hairs.  This is the final design.  It moves the intake to the top and away from the cotton candy producer.  It works.  I stripped the plastic off of a refrigerator magnet and glued it into a pocket.

    Thanks for this! I had no idea I had to clean the front fan every 90 days, but even though my fan still spins, it doesn't seem to be spinning fast enough to cool properly and I guess I'm having to replace it now. Hard to say, since Ultimaker doesn't have specs on the rotation needed and so *shrug* -- but I'm going to try both of these "mods" as I also have a Ender3 and don't want this to happen again to my S5 or to the Ender!
    This really seems like a design flaw in the S5, given its price and the fact that newer models have the fan placed to prevent the hairs from getting in the fan.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
