Hi, I’m printing a part that we’ve printed several times before. It was sent to reprint from the ultimaker website Digial Factory to a UM3extended. This file last finished successfully yesterday. Today’s print though has stopped at 90% and the screen says “Detected a move outside normal printer volume” and it won’t let me navigate away from this. The button is slowly flashing green and the print head is touching the print. Never seen this before. Clearly the print head is in the right place. Weirdly it says the print has finished in Ultimaker Digital Factory - not true. Please can you tell me how do I continue and prevent this happening again? (Cura 5.2.1 and think firmware is latest stable but can’t navigate to check) Thanks Guy

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 could have been caused by moisture in the filament creating a backflow, and perhaps the filament was too far into the head while the first PVA layer was printing. I set it up again after hot/cold pulls with the same filament having cut a couple of meters off it, and it printed without any problems.

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.

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

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 the photos, a wide flange has formed in the filament around the top of the tube going into the print core, which also means the filament can't be pulled up through the head. This also means I cannot remove the new print core or filament. It is absolutely stuck. The front fan is spinning OK and inside the head is clean and free of obstructions or fibres. This must be what had happened to the old print core with a different PLA, as when I tried a hot pull, the filament cracked rather than pulling out, breaking at this point and is impossible to remove. I'm not keen for the same result with this brand new print core and would like to stop this happening. Please can you suggest how to get the filament and new print core out, and what to try to fix the recurring issue? Thanks in advance

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!!

I have the same problem too. One hour so far. I’m going to leave it overnight

Have added a 2.2kg roll of material from ColorFabb to each of these

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

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.

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 whatever setting I put in Cura. I'm running Cura 3.1 and latest UM3+ Firmware 4.1.4.20171204 How do I get the support speed I need? Thanks

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 higher on the left / black end but we are talking >0.25mm Will try firmware and playing with the printhead cable but I really need a reliable printer... If it is the cable, is there a way to keep it in place rather than wait for this to happen again?

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.

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 build thin towers of PVA (which my UM3ext can't seem to build, especially on top of PLA) up to meet the side of any holes in the print, where previously Cura would have just created local supports inside the hole. I've never edited g-code but if I can't get rid of the PVA towers in Cura can I do it by editing the g-code somehow? I'd rather have a robust g-code file for repeated printing that has the towers removed or re-asigned to PLA (with the central support still PVA) if I can't nail the settings or get PVA to stick to PLA - is there a way I can edit the gcode to do this?

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 you suggest) - or selectively delete the worst ones in Cura - or selectively reassign them back to PLA in Cura Any other ideas welcome Thanks
