Difference between detected height of both PrintCores exceeds realistic values (S5) Uploading as after many months of repeat sending of jobs to overcome this error when auto leveling. We have had this issue intermittently since receiving printer and just assumed it was just the norm. We overcame it by sending print job again and if that was unsuccessful, by then unloading and reloading printcore BB0.4. Sadly we had our first ever significant print fail with a 15 hour job and were met with a giant bird's nest and a jammed printer, with filament wrapped all around Y axis mechanism. It had even caused the Y motor to move thus requiring us to retension the belt. Anyway, after clearing everything out, and getting the machine up and running it started failing every time during the auto leveling process at the start of each print. Finally to the point (sorry for the waffle) it turned out that the silicon nozzle cover was the issue, further more the little metal plate inside the print head that helps retain the nozzle cover was bent! After removing and straightening the said metal plate the silicon cover fits better than it has ever fitted (since even from new- I always thought it looked a little saggy). Also the magnetic catch functions better than ever before! Hopefully this will be useful to others in the future as we had tried everything suggested on the main Ultimaker trouble shooting guide and various searches have not stated this solution. Point worth noting is the auto height was triggering fault as soon as it tried to action the auto height on the second nozzle - the nozzle was nowhere near the build plate - can only guess the metal plate was forcing pressure on the nozzle causing a false positive. Kind regards, Daniel

I have only had the machine a week, and the first thing I noticed before even using any filament was how easy the front flap opened. Oh well I can't be too wrong as there are at least two fixes for this on thingiverse.

Sorry forgot to point out I have a very weird sense of humour - please don't take any notice ?

????? - is this an attempt at humor or is your link broken ?

I posted up a good five pics. I can't see them - maybe I have to insert them - let me look HAVE NOW ADDED THEM -

The fan cover - you can see the pic with the improvised spring.

Oh please elaborate - what needs to clip in, is there a tab or something to look out for?

Hi all new to this forum. I am a teacher and managed to get an S5 :). Having had a 2+ extended I knew my next machines needed to be Ultimakers. The students were nearly falling out last year due to the waiting times, their mastery of Rhino (3D CAD) had meant they were all desperate to print! Have KS4 and KS5 classes using 3D printers but want to get KS3 groups using them too so have also got a new 2+ just to give me more printing capacity. OK, new S5 machine arrived and having spent many an hour stripping PLA support material I was excited to finally try PLA. I quickly mocked up a design for a cactus, pot and little cap to close the base of the pot later. Idea is to make an illuminated USB extention. But main reason is to check PVA support effectiveness and to check the dimensional tolerance to create force fits etc. So, half way up the support, the PVA nozzle blocks (unbeknown to me as it was an over nighter) - tried again the second day after clearing the nozzle but same thing happens. Tried some manual advancing ( and that cold pulling technique ) of the PVA and a whole load of black stuff came out - thought this had solved it but no; still not working. Went in today and tried a new spool of PVA and the job is doing really well now - 2hrs left and the support part has finished! Problem is the old PVA is the reel supplied with the machine had only been opened minutes before the job. Also, what is with the nozzle cover any slight knock and it flaps down, even more so when nozzle 2 is down? I found two mini magnets and adjusted those which has improved the situation but seems a little worrying given it is a brand new machine. I have managed to use a small weak spring (you can see it in one of my pics) to keep the flap up and have cleared any filament between the silicon pad and nozzle 2 which did build up during the first misprint. Sitting at home like an excited child waiting for the final print to finish so I can pop up to the lab and get it. Darn ICT lot still haven't put the camera on the network so I can't view it from home ? Anyway - I have waffled on a lot but hello to all and thanks for adding me! Daniel
