  1. They work very nice out of the box. Only thing you have to "learn" is to chose the right profile. Even changing betweens cores (nozzles) is easy, the machine does reliable bed levelling, and also the first layer is no problem. The Um are the only printers where i fully rely on, i dont watch the first layer anymore...
  2. Like GR5 says, pva does not need much more then 10hrs exposure to the environement to become "bad" I only unwind the needed length from the spool, the rest of my pva goes directly back in a sealed bag with silica gel. For really big jobs, i use a drybox. But it you leave pva to long in the drybox (under 20% RH), the pva becomes to dry, and starts to be brittle. So, if you don't use the pva, put it in a sealed bag with its initial silicagel. Best practice 😉
  3. Sorry, I have no material station, don’t know how it would work? Maybe wind the length you need on an empty spool and load that in the material station?
  4. Welke printer? X-Y gecalibreert? Is je Pva droog? Werken let pva vereist grote zorg dragen rond de vochtigheid.
  5. I only unwind the length pva needed for the print. The rest goes back in the silica gel protected bag. Cost me some extra length, but i can use almost the whole roll. And the S5 stops when it detects end of the piece i cut. Btw, i use Polymaker PVA S1, never any problems since i use this method with this material. And, breaking pva is to dry, to flexible pva is probably to wet...
  6. PVA is very sensitive, like even 24hrs exposure to humidity can give big problems. In the early years i wasn't aware of this, and it made me having lots of troubles which i never could identify. Since i changed my behavior with these kind of filaments, i no longer have any problems. You can use a drybox, but, and this is my current way of working, you can also only cut the needed length of the roll PVA, and put the rest back in the original sealed bag with its dessicant.
  7. Yes, i probably wil try one out. The simplicity is everything! Also the printquality with the lightweight head.
  8. Great printer made better again! For me this is still the best Ultimaker in the pack.
  9. I use this a lot! perfect product for my mechanical parts. Although heath resistance is not high. I would say, dont go above 50 degrees celsius.
  10. Mine is in this state from the beginning. No reliable wifi connection. Don't know where the problem is. I guess my network. But there are no diagnostics utilities. So very hard to resolve.
  11. I love my S5, but the printer is not as precise (tolerances / elephant foot), as my UM3 and UM2+ I can't speak of the S3, but my feeling is that the weight of the head and the moving axes are the most important factors in this behavior. For me, the only thing missing on the UM3, is the filament detection. (and the levers of the feeder for easy loading of the filament)
