  1. All in all a learning process, and nothing really damaged! Amazing how, with PLA, just boiling water softens it enough to sort out what looks like a complete mess! Great forum
  2. Thanks for all your responses. I use hairspray to get things to stick and usually it's absolutely fine. I was having a few issues with this large based bowl though - some lines just weren't laying down properly. Then the problems happened! I guess it could have gone up past the shield and above the print nozzle - now its all fine though and my test print worked fine. I will be watching the video to see what more I can do to get the larger based pieces to stick. I had thought perhaps a higher bed temperature. The lump of PLA made the metal shields of the fan enclosures bend too, and scra
  3. Managed to completely clean the block in a glass dish of boiling water. Did the same with the nozzle external thread. Then went back to the printer, raised the bed and placed the dish of water on the bed to immerse the heater and temp sensor (with temp set to zero). This enabled me to then carefully pick off the PLA from those. reassembled, heated to 260 degrees to tighten the nozzle and now I'm doing a test print. Will post the result!
  4. Having used my Ultimaker 2+ purchased form you in December quite successfully for many weeks, I had a major problem develop with it during a print yesterday. I left the machine running for a few hours and came back to it to find this. The first photo shows the hot end after I partially disassembled it quickly to avoid it all sticking together with hot PLA. The PLA has leaked above the Olsson block and formed a large block of PLA around the Olsson heating element and the temperature sensor. By heating the block carefully after disassembly I have managed to free t
