  1. Hi there, i am modifing my UM2 original, and building a new, somewhat longer hotend. Does anyone know what setting in the firmwate you need to edit, to alter the bed leveling interface. If i start bed leveling now, my bed will smash into my new, longer hotend.... Gr Jan-Willem
  2. I guess that when you uncheck every one of the four boxes in the combine everything options it will work fine. You can find these boxes in the lower right of the expert settings. It usually works for me. Only once it kept in filling some of the layers. Have fun. Gr Cor.
  3. Hi there, i am currently struggeling with some retraction heavy print. (one of them involving a sharp pointed church tower) And i'm running into some problems. As i near the tip of the tower one would expect a blob of molten PLA forming at the tip, but wat i get is severe under extrusion..... I was hoping someone on this forum whas smart enough to write a plugin which would enable me to play with my retraction/de-retraction.... Somehowe i get the feeling that when i'm printing the tip of a sharp print, the de-retraction is in practice somewhat less then the retraction. But where repetier
  4. I trie to print as much in the back of the printer as possible and it seams to reduce this vibrations drasticly. Gr. Cor
  5. in my first example there are no curves at all. and the effect only shows when the object is nicely alingend.???
  6. the lower part is really the lower part. so the fan was at 100 percent after five layers. but the reason that the surface on the right look really bad is that Cura appears to have no problem with for instance a incredible high res cube... but if one of the sides point outwards (see my sample picture 2posts back) that is where the problems start. it also happens if the top of a nice cube was made round with a fillet.
  7. Just confirmed the "when it's alingend it seems more problematic theory" in this picture you see twoo objects printed tonight. Both same settings, same cura 14.03-test2. The only thing changed is that the one on the left is printed 15 degrees tilted clockwise. Wich seems to result in a far better product......
  8. Just posting the above i saw that when the object is neatly aligned with the x-axis. somewhere in layer 14 it starts producing massive amounts of g-code..... The shape is stil a sqare shap, but it creates a g-code for every segment of the stl... So that is also a bit weird... ;TYPE:WALL-OUTER G1 F840 X117.74 Y107.76 E7.95765 G1 X117.74 Y107.85 E7.95801 G1 X117.74 Y107.86 E7.95804 G1 X117.74 Y107.95 E7.95839 G1 X117.74 Y107.96 E7.95842 G1 X117.74 Y108.05 E7.95877 G1 X117.74 Y108.06 E7.95880 G1 X117.74 Y108.15 E7.95915 G1 X117.74 Y108.16 E7.95919 G1 X117.74 Y108.26 E7.95953 G1 X117.
  9. Hi everyone (Daid somewhat in particular) I have been playing around with some of the things mentionden above and found somthing interesting. When i was having trouble printing super high res stl, i saw that the inner contours sufferd much more speed variing issuses than the outer ones. (although the outer contours were stille very ugly). At first i thougt this made sense because of the higher speed i was printing the inner contour. Bur now i found out somthing else. When printing a shape like the posted picture, the outer contour (with no infill just testing) can be defined by 4 G-code
  10. sorry daid...i'm currently trying to manage my household...(four kids). will get back on this as soon as i find some time...
  11. no idea....i'm also a bit concerned about this, because the reason I set the resolution so high, was for me to simplify " gluing" stl files together in mesmixer...because of the insane number of triangles it was very easy to "boolean" the stuff together. so for me it would be nice if cura/um2 could easily handle this kind of detail....
  12. after a lot of experimenting I have found my problem.... it turns out that my stl output of solid works produced just too detailed stls... I selected a max stl deviation of 0.01mm (not a problem) and a max stl edge length of 0.3mm (big problem)...even straight lines get converted into very tiny segments of g code and this results in varying print speeds during printing an intended straight line.(very very ugly print results) ...for now results are fine we will see what the future brings.
  13. downloaded "test 2" last night. I printed one of my self drawn models. with a very high resolution stl... and there where still artefacts and ugly bits due to super slow and "hopping" print speed... I am currently not at home but will try to post some pictures later....
  14. Printing my longest Print yet.... 56 Hours... now 22 hours on the way, i just needed to post a picture.... It is planned to be 17cm high. Fingers crossed for the next 34 hours...... :???: :???: :???: :???: :???: just counted the number of retractions.... 200000. say two hundred thousend AAAAAAHHHHH That means that 200.000 retractions and de-retraction x 3.2mm means 1.2 kilometers of filament movement.... If my extruder survives i will be really proud...
