  1. Printer settings can sometimes be strange. I have a small part printed in different orientation:


    The right part is printed with a little support for the curved part that is sticking out. And the left part is printed with in model support. Printspeed and temperature and cooling (on) were the same for both printes. Well the right print is a disaster and the left part is very usable. I have printed them 0.2mm layerhight at 250 degrees at 50mm/s. It is clear that orientation has a very large influence on this design.

    On an other print I was printing at 260 degrees and it was very weak in some areas. Then I printed at 250 and it was strong..


  2. Well I have been printing XT with a little fan on. Giving the amount of problems you have it might help a little. I also print ABS with a little bit of fan. Don't overdo it with the fan otherwise you get layer bonding problems.

    If look at the photo drop the temperature a bit might also help fight the stringing (be aware that dropping the temperature might result again in bad layer bonding). And check your retraction distance.

    Well that is a lot to tune for. And conflicting actions it just looks like engineering.

  3. Draaid de z motor soms de verkeerde kant op waardoor die beneden op de endswitch komt? Als dat het geval is dan zou je de motor draden in de connector moeten omdraaien (ergens heb ik daar nog een instructie voor maar weet even niet waar, ik zoek wel voor je als je dat nodig hebt). Je kan ook een custom marlin laten bouwen waarmee je de Z omdraaid. 2 mogelijkheden om hetzelfde te bereiken..

  4. - De Z-axis die niet beweegt tijdens een print. (Bij de start van een print gaat deze wel omlaag indien deze nog niet beneden was)

    Hoezo omlaag het bed moet toch omhoog naar de nozzle toe om op laag 1 te komen?

    Voor je heated bed zou ik eens naar de power supply kijken. Note dat die PCB heaters behoorlijk veel meer stroom trekken dan aangegeven bij het opwarmen. Als ze dan op werk temperatuur zijn dat trekken ze minder stroom. Leuk voor het opwarmen maar slecht voor de voeding. DIt verschil kan denk wel eens tussen de 20 a 30% zijn. Dus als je voeding krap bemeten is dan trekt die het niet in de opwarm fase.

    De weerstand van PCB heaters loopt op bij oplopende temperatuur ...

  5. The original filament of ultimaker is quite smooth on the sides but colorfab has this little texture so I think that is causing it.

    The coming weeks I will be running some XT filament and that does not have this textured surface.

    I don't know what Arjan used for his experiment but he had also issues with PLA and the E3D. He did not use any oil.

    People report clogs with the E3D but I have never clogged the hotend.


    However if you plan to print PLA it will stick and get stuck against the metal.  PLA is very good at sticking to the metal and if you do any retractions at all (if you don't you will get horrible stringing) then your print will likely fail.  But ABS does not stick so much to metal and will work great.


    What is this...? Seriously?

    I have run lots of PLA prints with 6mm. @ 60mm/s retractions... Never had any PLA stick to anything...

    I also do not use sunflower oil...

    I agree with waiting untill the hotend is cold to turn off the printer....


    Well it is not the retraction that is causing the issue it is the friction of the bent filament touching the long cooler. Since colorfabb PLA is a little rough on the outside I think that that is the cause in my case that I get under extrusion. This is where my sunflower oil comes in. I think that smooth PLA it might not be an issue but I can't say from my own experience. I print usually at about 50mm/s for 0.1 layer height.

  7. I run quite a bit of PLA through my E3Dv6. I can say it only works well if I add 1 drop of sunflower oil to the filament (colorfab PLA) and after 12 hours of print it needs an other drop. No issue for me. Without the oil I get underextrusion there is simply too much friction in the hotend to get it through. Since I hardly print longer then 12 hours per print I don't have an issue but for long prints it might be. The benefit as I see it that the hotend can handle higher temperatures so for ABS and colorfab xt this is beneficial.

    I never had a clog but I only turn the machine off when the hotend is below 50 degrees (keeps the cooling fan of the hotend cooler running). Otherwise the heat can get into the hotend cooler and melt the PLA there which would result in a nice clog.

  8. Here my project has been growing over the last 2 weeks.

    I first made sections with one glass and I coupled them


    And now it is the final size and very difficult to move:)


    And here it belongs as you see the station still needs a lot of work


    But it is getting somewhere.


    And difficult to put it on my camera it is getting to big...

  9. The E3D is 12V but you can also get a 24V version for the same price. I bought a 24V version since it fits well with the 24V power supply of my heated bed. Running the E3D from 19V is a bit problematic. It eather gets too hot or does not heatup enough. I know some people using the 12V version on 19V and tune the PID bit stayed away from that. If you connect the 24V version with a external power supply make sure the 24V can never enter your board electronics. I connected it with a external mosfet just to make sure.

  10. To my experience it is not only the hotend that needs cleaning when going from ABS to PLA. In my printer small ABS particles travel from the feeder into the bowden tube. So when I switch I atomic pull with PLA a couple of times until it pulls clean. Then I clean the feeder with a brush and the bowden tube. If small flakes get into your PLA it can cause a clogged nozzle at PLA print temperatures.

  11. Hi Sander

    My phone is a Sony Xperia model MK16i. It is a little older device and it is running android 2.3.4.

    The previous version of the forum was no issue.

    The cause is probably that it is running 2.3.4 but it is a pity that it now fails so badly.

  12. Here is a good example what I don't like. I made a screenshot on how the forum looks on my phone (not usable and that is a pity)


    Now if look in my gallery it does not display it well. It only shows the thumb nail I guess. Here in the post it looks correct.

    For my phone this layout it hopeless I stopped using the forum from my phone.
