After 2+ days printing I made a ....leg !

You might also try to put some more weight on the Z-stage, this helped for me

This is the tallest print I have made so far, printed on my Ultimaker+ at 0.3mm layer height and is 36cm tall it was a test to see if my new Alu Z-platform would move smoothly, as I was getting gaps when it got stuck several times, due to being too light. took around 4 Hours to print.

Dremel is just a bad tool, it has only two settings, melting plastic fast and insanly- I dont't want to hold it in my hands -fast. I use a Proxxon, it is much better, 1- very good slow speed for plastics , 2- no more special 3.2mm bits 3-quiet !

I had the same problem, I had a lot of gaps on tall prints, making the Z-platform more heavy solved it for me.

Well after some bad prints and major overhaul of my Ultimaker+, I finally finished what I wanted to print for a while. I printed the TinTin rocket some time ago, but felt it missed something the rocket exhaust needed some major cleaning as it was covered in strings, and I still have to work out what is causing that. the base is made from 15mm polished perspex. and all the parts are connected with M8 rod for stability. https://dl.dropboxusercontent.com/u/8108870/IMG_1011s.jpg https://dl.dropboxusercontent.com/u/8108870/IMG_1008s.jpg

After some testing it seems the Z-platform is not moving smoothly, maybe there is some junk in there, or my design is just plain wrong then I would have to take drastic measures to make it stable. and also some shaking is also not making is a smooth surface at higher places.

Made my first tall print on my Ultimaker+, it took 30 something hours. it looks ok, but still need to work on the Z-axis, the print has gaps at multiple places. and lots of stringing on the bottom part. overall I'm happy with the result, but it needs some work :-P

After a 30+hour print on my experimental Ultimaker+, I noticed that Cura put some kind of plane or divider into the drawing ? It did not effect the printing as far as I can tell, but still am curious what this is.

Hehe no sorry, this is not your TinTin rocket, I drew this myself in Rhino3D, in segments one of my first bigger prints my Ultimaker+ can print up too 400mm in hight !, the rest is just a normal Ultimaker

do you mean Cura has a file size limit ? the size easily fits my Ultimaker+, and scaling the object would defeat the purpose of printing it, it is supposed to be a base for my TinTin rocket, and that too is pretty big

I'm trying to print a large object on my Ultimaker+, but Cura doesn't seem to like it, when I press print, the dialogue screen comes up, and the G-code is loading, but soon after it becomes unresponsive in activity monitor, even after 30mins. I tried several things: -several versions of the latest and older of Cura, same problem -printing a small object, works fine -using Cura on faster imac and transferring to print Mac mini, same problem. -just loading the G-Code, same problem. -rebooting, same problem. is it possible that Cura doesn't like objects larger then the normal size of the UM ? or is the G-code the culprit ? here are the files, if someone likes to take a look https://dl.dropboxusercontent.com/u/8108870/rocket%20exhaust%20combine%205.gcode https://dl.dropboxusercontent.com/u/8108870/rocket%20exhaust%20combine%205.stl thanks

I also think it would not be a great idea, as all the questions regarding UM1 are relevant for the UM2, and vise versa maybe for some technical aspects of the machine you can create a separate thread.

and are getting more popular

Nice to see a fellow R2Builder joining the Ultimaker party

Also same here, using the latest iMac. Help me obi-Dade kenobi !

I find Cura is not far off with printing estimates, I have printed some large objects, and after slicing I get a estimate of, say 40hours, but when I start to print the window gives a much larger estimate like 75Hours, but after around 30mins this goes back down a lot, and I must say that the original estimate is not far off after printing a lot of objects I have a pretty good idea what the total duration will be, and longer print times are more accurate the the short prints.

[Whiny voice] thanks Daid

Don't get me wrong, I love AutoSlicing, but the 20sec stuttering delay when making adjustments is just silly, that is a great example how AutoSlicing COULD work, but try that same trick with a 100MB file, and you won't be so happy I really hope this is just related to the wrong version in the OSX download, and that the latest version works better, or else I will be sticking to the old version :cool:

as long as Daid doesn't repair the download link for OSX, I don't know what version I have it says 13.06.02 in the header, but after installing the 13.06.03, it stil says 13.06.02 !!

well after a short time with the new Cura, here is my request so far - turn on / off auto slicing - center object on platform on / off - turn on / off auto slicing - turn on / off auto slicing - turn on / off auto slicing did I mention - turn on / off auto slicing (sorry about being a little miffed, not being able to use the new Cura)

My god Cura slices really fast, and works great....unless.... you have large files it turns my super duper fast new iMac into a slow 1990s pc ! every - little - adjustment - I - make - I have to wait for the slicer to finish doing its thing, -move the object to the center, wait......20sec. -lay flat on surface............wait 20sec. -rotate it to fit the platform, wait......20sec. -scale to the right size, wait.......20sec. -turn on support, wait......20sec. and so on... it takes 30 minutes just to load the object and have it placed and ready for printing, come on ! how come Daid never though about having an on / off switch ? is there a reason why this is not switchable in the expert setting ? I can understand to make an idiot proof program, but why make it more difficult for us, who use the expert settings. I have to stick with the older version, I rather press "prepare" and get a coffee, then to have to click every 20seconds for half an hour

Oh darn, I got confused with MeshMIXER :???: sorry ! watch this at the 3:36 minute mark http://www.meshmixer.com/download.html I find meshmixer works better them meshlab, and is more easy, all cuts made are always watertight.

Why not cut the model in Meshlab, there you can choose of the cut is closed or open.
