    silent ventilators

    When I got my Ultimaker 2 a few months ago the rear fan was really noisy and vibrated heaps. I also noticed on forums some people had quiet ones. I contacted Ultimaker and they sent me out a new one. Unfortunately it was just in an envelope with no protection and it gave more of a screaming sound. So I sent them a video and they agreed it's not normal. So now I'm waiting for my 3rd fan this time hopefully it will be in a box and will be nice and quiet.

    Head Hitting the sides

    in UltiMaker 3D printers

    Hi

    when I was printing something the other day that was quite large, the print head hit the right side when doing the skirt. it kind of kept going fine so i just left it as after the skirt it was fine.

    the thing that puzzled me is that it was blue in cura not grey and was central on the bed.

    I have now just started to try and print one of those wallets from XYZ.

    It was grey when i loaded it and after a lot of playing around i found it went blue after turning the skirt off.

    I kind of moved it away from the right side as much as i could as its very wide but when i started the print it hit the front and the belt jumped a tooth with a bang.

    So, If the item in cura is blue is this meant to mean its ok and won't collide or is it just saying yip thats on the glass or do I have a setting off?

    Thanks

     

    UM2 Raspberry Pi holder?

    in Coffee corner

    Posted

    My raspberry pi arrived today. I was looking for a case also. Cool to know there are mounting holes. There are also extension cables here http://www.bitwizard.nl/shop/rpi-camera-extension

    apparently they tested them successfully up to 4m/13 ft.

    I researched this before I order my pi.

    I was going to mount the camera at the rear by the stepper motors looking forward and run the cable in behind the covers. But seeing you can get really long ribbon cables it could run along with the led cables and up the front looking back.

    It would also take forever to print this especially if you want to paint it straight out of the printer. with all that detail you wouldn't want much cleanup work after printing before you paint it. otherwise you will be sitting there sanding until your graduation day, unless you vapour polish. if you vapour polish then you might loose some of those small details like the small spikes on its nose.

    You may want to find a new piece to hang on your wall. maybe a cute waving octopus?? :-P

    It seems like the day it will eventually be released will be a busy day for sales at Ultimaker.

    I'm just patiently waiting for it to arrive. If they release it to soon then it will be rushed, problematic and probably not the best solution. So it's better to give them time to implement it properly.

    When you dream about the possibilities and things you can use it for does really make you want it now though.

    It will be nice to have a bigger nozzle on one side so then you can use the bigger one for woodfill and other problematic filaments but still retain the smaller one for pla etc.. without have to swap out nozzles.

    Printing Filaflex

    Yeah I have seen this. Good cheap idea. I have found the chamfer on the snap on bit is to big and allows for much bendage. A bit of Bowden tube in there might help reduce the friction if there is enough room for it to. I'll see if I can make room for a bit of pipe cleaner. Not sure where they sell them here though.

    I'll try and jump on solid works at work and see if I can come up with something a little bit better for the snap-on piece. I have had it pop off both side of the bearing now. There must be a way to getting it printing a bit more reliable and having prints look more like ones on YouTube.

    I was thinking of having a auto oil wipe just after the knurled drive somehow. As long as it doesn't add any more restriction.

    I've had a similar thing with ninjaflex. I found by moving the knurled nut further in on the shaft (about 2-3mm so the textured part was more central to the filament) stopped the filament from slipping off :)

     

    Thanks, I'll give that a go first.

    Hey

    Has anyone found any decient settings for Filaflex on the UM2?

    Im using Roberts feeder and oiled the filament with sewing machine oil.

    I have tried the recomended settings and another I found on another topic.

    It will print fine but will still under extrude on a few layers every now and again and the finish is pretty rough. ( will Post pix later )

    I use Solidworks at work but since I got my UM2 I started to use sketchup make at home. It was easy to pick up and I'm still able to draw what I need at home but if I need a more complex design I just wait till I have spare time at work.

    I just wish solidworks did a cheaper home version.

    retraction

    Hi

    One of my prints just finished and I was watching it print the 2 last pieces. It was printing to tubes in PLA and one tube had stings coming off and the other was fine.

    I noticed it was only retracting from the tube on the Left to the right but when it would return from the tube on the right there was no retraction.

    would this be one of my settings or is it a fault Somewhere?

    I'm not sure how to post the gcode or settings here. If you need them I can find out.

    At work we Teflon coat alloy to use as seal heads to seal plastics. The Teflon prevents the plastic sticking to the seal head and We have Teflon coated steel and bronze etc as well. It's an industrial coating but similar to the coating on frying pans.

    The Teflon is sprayed on then baked but it can withstand temps up to 600 degrees.

    You could coat ceramic or another suitable material to lower the resistance.

    Actually Robert (IRobertI) has a great guide that he will be publishing within a day or two. It's very visual (lots of photos).

     

    Hi gr5

    Thanks for the great info. you do really provide some really great stuff on this forum. I had started some trials of my own and your info will save me some time.

    I will also look forward to seeing Robert's guide.

    It would be good to start something on wiki but I don't know anything at this stage so it would be very empty.

    Hi, I'm new to 3D printing and just received my New Ultimaker 2 a few days ago.

    After a few trials and printing various items with varied results. I had been reading heaps of posts here on the forum.

    I have found some good information but I was wondering if anyone knows of a good book to recommend or any documented format that explains how different settings can effect different prints?

    Something that has a basic explanation of material properties, causes of common problems and how to solve them.

    Also after looking at the settings in Cura things like wall thickness and speed variances between infill and outer layers. it Has a guide but would like to know a bit more of the background of why these cause differences to the finished results.
