  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 host has an extra option to de-retract more than retract, Cura does not. So i tried to write a plugin myself, but however how experienced i am at understanding G-code, "this challenge is beyond my skill" P.S i dont use ulti-gcode bur marlin/reprap...... gr Cor :mrgreen:
  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 X117.74 Y108.27 E7.95957 G1 X117.74 Y108.36 E7.95991 G1 X117.74 Y108.37 E7.95995 G1 X117.74 Y108.46 E7.96029 G1 X117.74 Y108.47 E7.96033 G1 X117.74 Y108.56 E7.96067 G1 X117.74 Y108.57 E7.96071 G1 X117.74 Y108.66 E7.96105 G1 X117.74 Y108.67 E7.96109 G1 X117.74 Y108.76 E7.96143 G1 X117.74 Y108.77 E7.96147 G1 X117.74 Y108.86 E7.96181 G1 X117.74 Y108.87 E7.96185 G1 X117.74 Y108.96 E7.96219 G1 X117.74 Y108.97 E7.96223 G1 X117.74 Y109.06 E7.96257 G1 X117.74 Y109.07 E7.96261 G1 X117.74 Y109.16 E7.96295 G1 X117.74 Y109.17 E7.96299 G1 X117.74 Y109.27 E7.96333 G1 X117.74 Y109.28 E7.96337 G1 X117.74 Y109.37 E7.96371 G1 X117.74 Y109.38 E7.96375 G1 X117.74 Y109.47 E7.96409 G1 X117.74 Y109.48 E7.96413 G1 X117.74 Y109.57 E7.96447 G1 X117.74 Y109.58 E7.96451 G1 X117.74 Y109.67 E7.96485 G1 X117.74 Y109.68 E7.96489 G1 X117.74 Y109.77 E7.96523 G1 X117.74 Y109.78 E7.96527 And when the object is placed somewhat at an angle (see picture in my previous post) the shape is maily defined by relatively long moves ;TYPE:WALL-OUTER G1 F900 X121.03 Y109.22 E30.24758 G1 X118.55 Y118.49 E30.28370 G1 X106.65 Y115.30 E30.33005 G1 X109.13 Y106.03 E30.36616 G0 F15000 X109.84 Y107.25 ;LAYER:88 G0 X109.20 Y107.31 Z5.53 ;TYPE:WALL-INNER G1 F1080 X109.42 Y106.52 E30.36923 G1 X110.30 Y106.76 E30.37265 G1 X110.78 Y106.89 E30.37454 G1 X112.24 Y107.28 E30.38022 G1 X112.72 Y107.41 E30.38211 G1 X115.64 Y108.19 E30.39347 G1 X116.13 Y108.32 E30.39537 G1 X117.59 Y108.71 E30.40105 G1 X118.07 Y108.84 E30.40294 G1 X119.05 Y109.10 E30.40673 G1 X119.53 Y109.23 E30.40862 G1 X120.57 Y109.51 E30.41268 G1 X120.44 Y110.00 E30.41460 G1 X120.28 Y110.59 E30.41688 chew on this daid...... :eek: :-P
  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 commands, and one could think that would also apply for the innen contours. But if you look at the sample of my G-code, it is clear that this is not the case.... Funny thing is, when this object is placed alinged with, for example the x-axis, the outer and inner contour for each layer do consist of only four lines. ;TYPE:WALL-OUTER G1 F840 X119.01 Y108.60 E8.52530 G1 X116.52 Y117.88 E8.56142 G1 X106.71 Y115.25 E8.59964 G1 X109.19 Y105.97 E8.63575 G0 F15000 X109.90 Y107.20 ;LAYER:16 G0 X109.28 Y107.19 Z1.21 ;TYPE:WALL-INNER G1 F960 X109.47 Y106.47 E8.63856 G1 X109.87 Y106.57 E8.64009 G1 X110.35 Y106.70 E8.64198 G1 X113.27 Y107.48 E8.65335 G1 X113.76 Y107.61 E8.65524 G1 X115.22 Y108.00 E8.66092 G1 X115.70 Y108.13 E8.66281 G1 X117.16 Y108.52 E8.66850 G1 X117.65 Y108.65 E8.67039 G1 X118.54 Y108.90 E8.67388 G1 X116.26 Y117.40 E8.70699 G1 X110.51 Y115.85 E8.72941 G1 X109.53 Y115.59 E8.73320 G1 X109.05 Y115.46 E8.73509 G1 X107.59 Y115.07 E8.74077 G1 X107.20 Y114.96 E8.74230 G1 X107.45 Y114.01 E8.74600 G1 X107.71 Y113.04 E8.74980 G1 X109.02 Y108.16 E8.76880 G1 X109.15 Y107.67 E8.77070 G1 X109.28 Y107.19 E8.77259 G0 F15000 X109.19 Y105.97 ;TYPE:WALL-OUTER G1 F840 X119.03 Y108.61 E8.81092 G1 X116.60 Y117.70 E8.84631 G1 X116.55 Y117.89 E8.84704 G1 X106.71 Y115.25 E8.88537 G1 X109.19 Y105.97 E8.92148 G0 F15000 X109.90 Y107.20 ;LAYER:17 G0 X109.29 Y107.15 Z1.27 ;TYPE:WALL-INNER G1 F960 X109.47 Y106.47 E8.92417 G1 X109.87 Y106.57 E8.92570 G1 X110.35 Y106.70 E8.92759 G1 X113.27 Y107.48 E8.93896 G1 X113.76 Y107.61 E8.94085 G1 X115.22 Y108.00 E8.94653 G1 X115.70 Y108.13 E8.94842 G1 X117.16 Y108.52 E8.95410 G1 X117.65 Y108.65 E8.95599 G1 X118.57 Y108.90 E8.95961 G1 X118.33 Y109.79 E8.96306 G1 X118.21 Y110.28 E8.96495 G1 X117.94 Y111.25 E8.96875 G1 X117.81 Y111.74 E8.97065 G1 X117.03 Y114.67 E8.98205 G1 X116.90 Y115.15 E8.98395 G1 X116.51 Y116.62 E8.98965 G1 X116.38 Y117.10 E8.99154 G1 X116.30 Y117.40 E8.99271 G1 X112.97 Y116.51 E9.00568 G1 X112.48 Y116.38 E9.00758 G1 X111.51 Y116.12 E9.01137 G1 X111.02 Y115.99 E9.01326 G1 X109.56 Y115.60 E9.01894 G1 X109.08 Y115.47 E9.02083 G1 X107.20 Y114.96 E9.02815 G1 X107.33 Y114.47 E9.03007 G1 X107.46 Y113.98 E9.03197 G1 X108.25 Y111.06 E9.04337 G1 X108.37 Y110.57 E9.04527 G1 X108.64 Y109.59 E9.04907 G1 X108.77 Y109.11 E9.05097 G1 X109.16 Y107.64 E9.05667 G1 X109.29 Y107.15 E9.05857 G0 F15000 X109.19 Y105.97 ;TYPE:WALL-OUTER and when placed neatly alingend ;TYPE:WALL-INNER G1 F2400 E3.24576 G1 F900 X117.01 Y108.10 E3.38543 G1 X117.01 Y116.90 E3.52337 G1 X108.10 Y116.90 E3.66304 G1 X108.10 Y108.10 E3.80099 G0 F15000 X107.70 Y107.70 ;TYPE:WALL-OUTER G1 F900 X117.41 Y107.70 E3.95320 G1 X117.41 Y117.30 E4.10368 G1 X107.70 Y117.30 E4.25589 G1 X107.70 Y107.70 E4.40637 G0 F15000 X108.70 Y108.70
  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...
