    Have to ask though, mostly because it would have been the first thing I did..

    Did you touch the hot bed where it says "do not touch"? :D

    Of course, and I always touch wet paint and walk on the grass that's what those signs are for lol

    Hi,
    If anyone in the UK would like to buy a 3D printer I have two for sale.
    I knew the novelty would wear off after a few months.
    Both work well and could be fine tuned to work even better.
    I have got my fishing tackle out of the shed.

    I've been thinking about buying one Ian but don't have a clue how they work?

    These have been set up and just require STL files to make them work.
    I`m not very good with computers so I can`t design my own stuff for them but you can down load lots of things from thingiverse and other sites but they have mainly nerddy things I`m not interested in.
    If you have kids they would be great fun for them and if you can operate a CAD system they are great for making parts for planes like Sterling and Malukk does.
    I thought I would be using them to build planes but I`m not convinced the printed planes would be suitable for where I fly.

    Now that's a bloody good idea!

    I was considering somehow making a holder for multiple servo leads so I could bundle them into a single "plug". Was awkward with all the connections in the Hawk but the "winter" build I've got planned (more to come soon, but it'll be a big one again) will need at least 5 per wing so as you can imagine a single plug option would be a great advantage!

    I can send you the .stl if you have a need for something like this. You just need to order the connectors.

    This one is set for an mpx-8. I can adjust for an mpx-6 tap quick.

    I've not decided on how it'll all be connected yet but the file would come in handy if I do decide to use the mpx connectors.

    You may recall I printed this.
    TallThin1.JPG
    It was a part for a printed 'pod and pylon' for a 52" pusher plane.
    Complete2.JPG
    I commented that 3D printing was not really an economic use of time as I was never going to make more than one.
    How wrong I was! Whilst flying a bit too enthusiastically the wings 'clapped hands' and separated from the fuselage. That beautifully streamlined pod came vertically down from a 200' and buried the nose (& battery!) up to the start of the wing pylon. 09Apr18.JPG
    The wing halves are virtually undamaged as they 'fluttered down' long after the fuselage! Surprisingly all the electrics survived.
    So I do need another complete set of printed parts! As well as some fairly serious repairs. :eek:
    So after good number of printing hours we have Big Dragon 2.1
    19May18.JPG
    You would be hard put to tell the difference and it flies just as well too but this time that centre wing joint should be significantly stronger. ;)
     
  14. It's bad when wing tips clap, right??? ;)

    Hi Chaps, I am having a few under extrusion issues when printing at 0.4 shell width (3dlabprint). I am using an old version of Cura because my PC is only 32bit and on the whole I think I am pretty close, I have correctly calibrated my esteps for the extruder, but every now and then I have this issue, anybody got any ideas? thanks in advance

    I'd say it was the slicer running it a bit thin at those points and the extruder not being able to keep up effectively.

    Have had problems slicing thin wall properly in anything other than simplify3d but it's not a cheap option sadly.

    Thanks Leigh,
    you could be right as it does do it repeatedly in the same place, I was having a look at S3D and yeah it costs more than my printer lol, plus I would probably have to upgrade my pc as well.

    I have started to play around with some more settings on a simple oval tube and see if I can improve things. It prints the parts off perfectly at 0.8 wall thickness but unfortuately it would weight the same as a boat anchor and probably fly the same way!!

    Incidently, what do you personally use to design parts? I have downloaded Rhino and it looks like a bit of a steep learning curve for an old duffer like me!

    For most of the stuff I do I use TinkerCad as it's quick and easy.
    I've been using rhino but I really need to spend some time really learning how to use it properly I think!

  19. I would recommend setting up the extrusion width to 0.42mm and try in cura along with printing at a little high temp. But then if you get more stringers, you’ll have to play around with speed and retraction.

    Thanks for your advice, I will give that a go:)
