  1. Hi Guys

    So I have been printing some parts for an air duct which need to fit together squarely. I had some problems with warping in corners and went through this forum for tips.

    I tried the disc method where you incorporate discs 0.2mm thick at the corners of the base of the object. I used a varying diameter depending on the size of the object and also changed the first layer thickness to 0.2mm and made the fan turn on during the 3rd layer rather than 2nd. I can safely say that warping has been almost eliminated. :D

  2. Hi guys - I started a print last night which cam to an abrupt stop after one hour. On inspection I found the PLA I was using got stuck just before the nozzle. On measuring the filament I found it was 3.2mm!

    This is a silver PLA I bought from ultimaker back in June. Measuring at different points gave me a range of thickness from 2.8mm to 3.2mm! :oops: It's so bad you can even see the thickness variation with your bare eyes!

    Do I have a bad batch?

  3. I tried 12.12A but still no luck. Strange thing is I was using the older 12.08 fine - but 12.12A just doesnt show me the preview window - and I have uninstalled 12.08 already so now I am not able to do anything :|

    Daid - I have the drivers and Direct X installed.

    Is there a link so that I can re-install 12.08?

  4. Hi Guys

    I just tried to install the new cura on Windows - it seems to install fine but then when the main window opens, the preview window showing the object etc just doesn't show. it's as if the program is crashed but I can go through the menus fine. I have tried reinstalling a few times now but same problem.

    If i move the Cura window around on my desktop the preview window has a trail of menu bars - if that makes sense?

    What am I missing?

  5. Hi Guys - so i printed "The thinking man" last night at 0.1mm layer height and 2mm retraction. I am using the V2 hot end and extruder. This is how the print came out - as you can see there seem to be some layer "shifting" going on? You can see the lines more clearly on his back. Any ideas what might be causing this?

    I have aligned the belts and clamps. I also have additional tensioners on the belts.

  6. Hi Guys - so I printed and installed some belt tensioners to get the belts to "sing" as per the instruction video. I also realigned the axes - but now I find that there is a lot of resistance in trying to move the head by hand. It isn't free at all as shown in the assembly video.

    With the lower belt tension (which was very low) the head felt less resistive (obviously) so I'm not sure if there is something I have missed - or use less tension in the belts?

  7. or, once you've loaded the model in printrun, go to the file menu and select edit. Change the second line with the M92 Exxxxx with the xxxxx being the value you want.

    Right.

    Also, I dunno M2210 but Joergen is usually pretty clever so you may want to look into that, too.

     

    In print run if I extrude 50mm the actual length drawn is about 46mm.

    If you didn't already know, multiply your current esteps value by 50/46 (1.09) then measure again. Keep repeating and adjusting esteps by desired/measured until it starts behaving.

    Thanks - I did this and entered the new value in Printrun, then clicked extrude again - but it didn't change the length much. Out of interest I entered an E value of 850 and 1050 and did the same 50mm extrusion - the length was the same - around 46mm??

    When you change the E value through File - Edit, does it only change when you print the model or does it change globally and thus should take affect when you click the extrude button?

  8. Hi guys. Recently picked up some blue glow in the dark filament which I am having trouble using. It almost looks like it comes out of the nozzle like a gel and forms little lumps which stick to the nozzle messing up the print.

    I have tried increasing the temp to 215 but still giving me trouble. Any tips??
