  1. You will also need to install new library to your computer to handle these extra characters. My experience wasn't so good with this full graphical display, first of all, it doesn't give more information than i expected, or in other words it's not as usual as i thought it will be. But the problem i was encountering that this display was taking much more juice from my arduino than i thought and print quality was much worse.. for e.g. if i would press my encoder during print, print would even pause for 0.5s or so until menu opens... But i heard that other people had much better success than i
  2. Guys, you could also use the PCB cooling fan circuit with 7812 voltage regulator, just split output to 2 fans and it will work fine. As long as the total current use is no more than 0.6-0.8A you will be fine.
  3. So when it is printing and when you click your encoder, to go into menu, does the print slow down or even pause? Or when you print a part with complex shapes, doesn't it work slower? That is very weird. I have tried mine, but since it affected print quality i have decided to go back to older controller. Also I did some research online and found that this full graphical LCD is not recommended to delta bots, since it's too much to handle, so i thought that this might affect my printer as well. Any ideas what could be wrong then?
  4. Smaller controller, like ulticontroller with 3 lines, works just fine, but that big display looks like was too much for arduino to handle..
  5. Does anyone notice that their printer is working much slower with this full graphical display? I have tried using it, but it almost looked that it was too much for arduino to handle and when printing you could see micro stops of the printing process.. and if i would press menu while printing, everything would micro pause until menu opens..
  6. With your help i think i have found a problem. If I scale whole model (uniform scale) - print path looks good (no extra moves around) If I scale only Z - it doesn't work anymore and it creates extra paths. Thank you for your help on this!
  7. Could you give a try with my stl file and see if this happens as well? Like i've wrote before - i scale only Z to 150 mm.
  8. Here is an stl file that i want to print, i scale Z down to 150mm, leaving X and Y the same: Link My cura settings are:
  9. I've tried cura 14.01 - no changes, it still generates rapid movements from one side of the print to start point allong these narow ribs, this will again create strings that will eventually block heads movement and steppers will loose their steps.. Any other ideas? Is this fixable at all? I cant print this
  10. I've tried newest cura beta 15.10 but there i cant seed movement paths at all.. I will a shot with with older version. Thanks
  11. Hi, I am trying to print spiral vase. I use cura 15.04.2. Everything looks fine, except every few layers, cura creates a path for a print head to move back to start point.. This rapid movement back, goes in a path, that create some strings (retraction does not happen, even though it's set to 1.5mm). After some layers, print head just gets stuck to some of these strings and then steppers loose their steps and the print is ruined. Is there any solution to this problem? I can't find a way to change that. Tried printing slower still same problem..
  12. Hi, I have some random scars on my printed parts. Most of the part looks good, but at random location, some blobs appears. What could cause this? Any ideas?
  13. I've partially fixed the problem. Spend a lot of time investigating, and found out that the extruder feeder hobbed bolt was not working as supposed to. So i've made a new hobbed bolt, now it works much better. Though very rarely, filament slips and after some time i can find some filament chips on the table below feeder mechanism.The feeder is tightened as much as i can, maybe i need very strong spring there? what do you guys use? Anyways, i want some more opinions now. It prints way better than before, but i get horizontal lines on my prints. Check the attached pictures. What could b
