  1. Thanks for all the suggestions. After a lot of wiggling and pulling, I was able to pull the bowden tube up from the head - pulling the ground end from the feeder into the bowden tube. That gave me a bit of slack and I was able to expose more of the filament by undoing the 4 long bolts on the head to increase the gap between the core and inside top of the print head. That gave just enough space to bend the filament and pull the core out - the filament was actually not stuck in the core, just the melted collar it had made couldn't go up or down. It
  2. Yes I can see how the front fan not working could cause this. But the front fan on my S5 is working OK. I've been offered a back-to-base repair by the reseller, or a new head, but would really like to be able to fix it myself as the print core is brand new.
  3. Hi, Yes its 2.85mm 'Standard White', and the same happened with the old print core using 2.85 orange The printer is otherwise working normally and I can heat the print core, but it is not possible to pull the print core out with filament that has formed a flange like this as it cannot move up or down and the gap between the print core and head is too small to bend the filament to pull the print core out. I'd also really like to work out how this is happening in the first place. Recently updated the printer to 6.3.0
  4. Hi, I have just replaced my S5 print core, as PLA became stuck in my old one, and the same has happened on first use with a brand new print core. With the brand new AA0.4 Print core, I successfully loaded white ColorFabb PLA which extruded ok, and had printed XY calibration OK. Set it to do a weekend long print on Friday and left it while it the first support layer of PVA was printing from the other BB core. Today it looks like the PLA was stuck even before it started printing and I cannot remove it. Looking at the printer closely in
  5. So it was still like it this morning. OFF and ON seems to get it going again, though this is the one thing it says on the screen NOT to do!!
  6. I have the same problem too. One hour so far. I’m going to leave it overnight
  7. Have added a 2.2kg roll of material from ColorFabb to each of these
  8. Hi, We have 3x Ultimaker 2+ Extended for sale if anyone is interested: http://ebay.us/XfoFa6 All very good condition and well maintained with new parts. They include the long and short spool holder, new nozzle and original packaging. Would ship by DHL and include a test print. Selling to upgrade to an S5
  9. Ah - I think I've found out more The the slow support speed setting only works on the second layer. The first layer everything is still printed the same speed which seems to be Initial Layer speed whether support or not. So only the first layer ignores the Support Speed, but it would still be helpful to be able to set this as the default is still too fast for the PVA to adhere to the build plate. Changing this to 10mm/s now works for PVA but also makes the rest of the print very slow.
  10. Hi, I'm having problems with Cura settings not being recognised or used while printing I want to set the PVA support printing speed to 50% of the PLA print speed. This is the only way I can get a particular print to work, as the PVA normally creates a birds nest. If I manually slow it down while printing PVA it prints OK but I have to keep watching the print. In Cura I have set Print Speed to 35 and Support Speed to 15, but they still print at the same speed. I've tried resaving, renaming, resetting, even experimenting with Support Speed of 1mm/s but it still prints support PVA at 35mm/s
  11. I'm also getting this error ER19, it happened 95% through a 4 day print that it had managed OK previously. It has just failed again with the same ER19 just over a day into the re-print. It seemed quite happy after a restart to have another go before it failed again. Spent a week on this so far :( I've attached photos of both prints at the point the printer broke down. Already reached out a few times to UK support but they have not seen this error before on an Ultimaker 3 Taking the cover off and looking at the connector it looks seated OK, it is flush on the right and possibly a tiny bit
  12. Thanks Neotko! I'll start again with these settings. If anyone has thoughts on selectively editing supports to get rid of thin ones or selectively assign materials to them I'd be really interested.
  13. I'd also add Cura 2.3 generated more supports for the PVA than I'd previously had. I have already printed this 54 times on my UM2+Extendeds single extrusion and it takes an hour or so to clean up each one. The Faberdashery White PLA gives an excellent finish - no bobbles or stringing, but I still have to hand finish where the supports join the housing. It would be really nice to just dissolve the supports with UM3ext dual extrusion, but once I've dissolved the PVA that has been dragged through the walls it will have lots of holes and the part will not be presentable. Cura seems to want to b
  14. Hi, Thanks for the reply. I agree PVA sticks to the base! I guess it is not clear enough from the photo so I've taken a screenshot of Cura at this layer of the build It seems happy to build fully enclosed PVA supports (in the rectangle top right) But you'll see from the Cura screenshot there are freestanding towers of PVA that it generated that in the photo are now the debris that is penetrating the PLA on the left hand side. So for these PVA supports which are causing problems, ideally I'd like to: - change the settings so they build correctly (maybe "support horizontal expansion" as
  15. Hi, I'm printing with Ultimaker branded PVA and Faberdashery White PLA. From experience the Faberdashery White PLA is a very reliable material to print on my UM2+s with. I'm not sure the settings for the Ultimaker PVA are working at all well though - what can I try next? Attached is a photo - you'll see the UM PVA is a birds nest mess creating loose debris, which is also getting dragged through PLA regions. These are out of the box settings for a new UM3 extended on "Normal" quality with support "everywhere" with standard settings/cores for PLA and PVA. I think the default with PVA is als
