  1. Given that Ultimaker gave up on the aluminum build plate, would it be possible for them (as an open source company 🙂 ) to release the data and specs that lead them to that conclusion? There are enough engineers/designers etc on here that someone could make this work in much the similar way to the olssen block/dual extruders that were made for the ultimaker2's? Surely that has to be more of a compromise position than 'we cant get it to go, so you cant have it'? and gives people the option one way or the other? You never know, you could even solve these 'issues'. I'm pretty sure that those that absolutely want an aluminum build plate could get their own made and possibly work around any issues that Ultimaker came upon?
  2. Having had Ultimaker 2+'s before, I just bit the bullet and got a new Ultimaker 3 extended! For the first couple of big prints that I've generated, Cura is coming back with print times in days and not hours :( With this in mind, I was thinking that there's a good chance that with that amount of time exposed to the air sat on the back of the printer, my PVA is gonna be in a pretty poor state by the end, so my question is this - what do you do when you've got a long print using PVA? Are my concerns real? Is this a non-starter beyond a certain time period? Would I have to pause the print, remove the spool and bake some moisture out? I'm also thinking about getting some 0.8mm cores so does that make my life easier in this case or worse? I've got both Ultimaker PVA and some Formfutura stuff so not sure if they're going to behave differently..but either way, I dont want to come back to a print after a day or so and find that the support materials not extruding/jammed or fizzing all over the printbed.. Thanks in advance.. Shaun
  3. Thanks for your responses so far - I must admin that I am a bit surprised that for something as exacting as getting the prints to stick to the plate especially with the .25mm nozzles that the whole affair is so hit and miss. I'll give kolia's suggestion a try and I'll feedback when I get the chance Shaun
  4. Hi, Coming from a print background where 'level the bed with a sheet of paper' gives a huge scope of variety, I'm coming to the conclusion that my best bet would be to use a metric feeler gauge to get the exact distance set. So, my question would be, does anyone know the required distance from nozzle to bed required to get the .25mm, .4mm and .8mm nozzles to work without playing the 'adjust it when it's starting to print' game - something that I really dont want to do with the .25mm nozzle in case I crash into the build plate.. Is it dependent on the first layer height and so depends on this or is this an absolute value and the printer takes care of the rest? Regards Shaun
  5. Nozzle unclogged and then found that the filament wasn't feeding at all....tried a different filament and now all is well :-P Cheers..
  6. Hi, Just got my hands on a used Ultimaker 2 and am having a few teething problems (jammed nozzle for starters!!) Anyone in the local area, feel free to get in touch as I may need your expertise!!! Thanks Shaun
