  1. I'm pretty sure the ironing is applied to every flat surface you can see the thinner neosanding lines on both these flat surfaces on the same part Hi catohagen ! Good point , you're right ! I apologize to Cura , it's smarter than I thought, as I did not see any layers options in Ironing's settings, I thought that by default it would concern only the final top layer of the print. It works quite well, the result is not yet perfect time to practice more this feature and its settings !
  2. Sure nilrog you're right ! I had thought to this too, it was just for discuss...
  3. Hi ! without panels or additional cross reinfort tubes, despite a very tight corner junctions, with time any extruded aluminium structures would move as a 3D deformable trapezoid !
  4. Hi amedee Yes it's what is planned for the final
  5. I did a year ago. Transformed UM2 having corexy inside the frame, while using standard UM2 firmware. I did have some problems with "define Quick_Home". You should not use this option in combination with corexy. I'm also thinkering on dockable um3 cores. Downside of using ultimainboard, is having only 2 heaters available (+build plate ofc). While using corexy, there should be many more cores inside... Hi and thanks EdgE ! As it's very modular this cooling fan design could be applied to any print head system. For the coreXY project I'm not yet at the firmware management stage but I
  6. Hi to all ! Mark2-Dual ZGE more and more tests..... Cura 15.04.6 vs 2.7 version, with same basic print settings old Cura 1h28 2.7version 1h49 here the result before post cleaning of the print test done it seems a bit better on the right with Cura 2.7 vs the left sliced with the old 15.04.5 version, better temperature control ! It 's really a shame that Cura did not think to allow the Ironing application to specific layers during the print and not only on the last top layer which in many cases is not necessarily flat, as the sample here, or as thousand of others print model
  7. Hi ultiarjan Ofc I can! it's really worth to try, it will more reliable than the UM2 hot end I 'm in updating the design files for improving more some details noticed when testing, just wait a few days, time to complete the folder, included step, bom etc....
  8. of course neotko ! The subject here is the Mark2 Dual ZGE, it was just an ad effect when the project is more advanced I think it will be necessary to open a post specially for that
  9. Yeahh! CoreXY UM system upgrade... Now that gonna be a fun ride! the future to complete the whole UM heavy mod ! May be we will need a serious Main board to manage all this, a Duet3D for sample ?
  10. You know... New short belt pulleys (a-la um2 gt2 single dual pulley) New Z endstop New gudo-neotko-beyond slideblocks Done neotko we are a winner team ! and in very soon , the UM XYcore system !
  11. Thanks to you all ! @ catohagen Hummm!.... we are always more creative when we have small means and we can think more freely ! btw, today I tested an anti oozing device, it seems it works great, more long time print tests will confirm. The device consists on the use of a 0.08mm very flexible metallic strip on which the noozle tip comes to rely at the docking postion, as after docking retractation there is no pressure, the very very light metal contact, less to 2 grs. pressure force on the nozzle tip, is enough to stop the eventual material dripping during the docked head standby, the
  12. Thanks much ! your appeciation rewards all efforts.
  13. Hi to all ! Thank you neotko for the introduction, also thanks for the support and help of the entire Mark2 team, sorry for not mention all the names, you will easily recognize. As you can see, the goal was to adapt the ZGE DD extruder to the Mark2 magnetic tool change, for reasons of room in order to install a Dual ZGE, it was necessary to review and modify the Mark2 magnetic tool change system , print heads and routing while respecting as closely as possible the the Original Mark2 operations. It was necessary to install a second docking holder mirrored with the front right docking at th
  14. Looks like the light blue material was slightly too hot? Hi ! Yes you have a good look, I thought so too! 200 ° is not so exaggerated for PLA Polymax ? it's a old spool that I had in stock for a year, I think it has degraded and in addition, as the tool change sequences are very short, with the slight overshooting during this it oozed very easily.
  15. sorry ! I wanted said 0.4 nozzle, 0.1layers
