  1. @MobyDisk Thanks for the reply. I had the same idea about the support horizontal expansion, and i increased it before starting my second attempt. Will se how it comes out tomorrow. As for the extruding problem. After my first attempt i printed a different part at 0.1mm using the same PVA spool and it came out perfect. So i dont believe it's the spool. ( is there a way to see the production date of the spool? ) The problem comes when it has to create the support inside the part ( picture a rectangle with one side open ). The printer goes along the path of the support buth extrudes just a few mm of material and the jumps to the next. After it skips a layer the rest ( if material extruded ) are useless. Meanwhile the prime tower is perfect. Sorry i cant provide pictures, im at home now and the printer is at work.
  2. Has any one managed to print Ultimaker PVA at 0.06mm or 0.1 and short lengths? I have a part that has to be with a tolerance of 0,1mm. The PLA prints perfect but the support is bad, it doesn't extrude the material correctly. This is with the prime tower. I have noticed that on short lengths (5.5mm) it doesn't work well. The prime tower is perfect, but the support isnt. Any advice?
  3. Brand new 500g PVA spool and BB core. I cleaned the core after each attempt. It still hapends.
  4. HI, My PVA clogs the nossle (BB 0.4mm) 30min to an hour in printing. It's like baked. Any recommendations?
  5. Has someone tested a material that withstands 250C (form a fan) that can be printed on a US5 printer with PVA support? I have a searched the marketplace but max spec is 150C+. Thanks
  6. The S5 is set to auto update the firmware. This should resolve by itself. On Monday i will see on what firmware it's running
  7. Hi, On every print i get a popup error on the printer touch screen saying that the print job was sent from a Ultimaker Cura 4.4 or older but we all use Ultimaker Cura 4.12. This started happening after some update of the printer software and Cura. This happens from multiple PCs. Any ways to fix this?
  8. Hi, Like it says in the title. After an hour or so of printing the core clogs. The first layer is ok but after it goes to standby once it doesn't start again. it's clogged, burned in. if some PVA comes out of the extruder is yellow and brown. I cleaned the core 3 times today and the cleaning filament on the first cold pull was brown. I dried the filament on the printer like it says in the PVA manual (on 55C for 2h) , but it didn't change anything. I reduced the standby temp to 50C but when i monitored it the nozzle temp got down to 200C and it was time to heat up again(it went down slow). I set the printing temp to the minimum and it was the same. Next i plan to set nozzle switch retraction distance to something like 80mm and speed this up by 30%. Does anyone have any other suggestions or has tried something else and it worked (or didn't so i can skip it)? The print is 1d19h long. The first time this happened 20h in. I don't have a filament drier yet. Hope to hear your opinions and advice. Thanks.
