  1. Yes, that's right, when the bridge settings are not enabled, it just prints using the normal settings for walls and skin.
  2. Hello @perplex, when Enable Bridge Settings is not checked, none of those settings are used. There is some legacy code in Cura that detects unsupported skin regions and modifies their alignment but other than that, there is no special handling of walls, etc.
  3. https://github.com/Ultimaker/Cura/issues Please make sure you fill out the issue template and provide sample .3mf and gcode files, etc.
  4. FreeCAD says that it has "flipped normals". I un-flipped them and it now looks to slice OK. The Cura mesh tools didn't barf on the original file. Should it have done @ahoeben? bowl-flipped.stl
  5. Hello @bkrahmer, that sounds like it is an issue with the model. Could you please attach it to this thread. Thanks.
  6. Hello @ssashton, if you are using Cura on Linux or Windows, you may wish to try one of my builds that has extra settings for slowing down the printing of walls when the length of the feature is small (i.e. like a small diameter hole). The builds also contain many other bug fixes and improvements that have still not been incorporated into Ultimaker's releases. They can be installed alongside the Ultimaker releases. If you are interested, take a look at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0
  7. Re-reading @redslifer's words, if there is delamination then that would suggest too much cooling fan or too low temps.
  8. Hello @baxi, thanks for the files. I still think that you are likely to get underextrusion due to the long un-retracted travel moves so please try setting max comb distance with no retract to something like 20. Also, don't use the sharpest corner z-seam alignment as it rarely does what you want (model dependent). Instead, use the user specified location to fix the z-seam where you want it.
  9. Thanks. Actually, the STL isn't much use on its own. Far better is to save the project and attach the .3mf file as that has both the model and the settings.
  10. Hello @baxi, please attach the gcode file that exhibits this problem.
  11. My guess is that you are getting underextrusion following long un-retracted travel moves. Try setting the Max Comb Distance With No Retract to 20 or similar.
  12. Hello @obrterry, that setting is only visible when the infill density is > 0, the infill pattern is not cubic subdiv and spaghetti infill is not enabled.
  13. Hi @smsusi, looking at the Cura source code, the only effect that selecting Mach3 flavour is that the extruders are named A, B, C, etc. rather than E.
  14. OK, so what about the difference in retract amount & speed I mention above?
  15. BTW, are you printing these two gcodes using the same method? i.e. both from SD card or both using USB with the same host program?
  16. The next obvious difference is the repetier code is doing 6mm retracts at 80mm/S and the cura4 code is doing 4mm retracts at 30mm/S.
  17. Thanks for the files. The most obvious difference is that the cura4 file has part cooling fan running and the repetier file has no part cooling fan.
  18. Do you still have the gcode that produces a better result? If so, please attach it to this thread so I can compare it with what is produced now. Thanks.
  19. Hi @smsusi. Until recently, there was a regression in Cura whereby the mach3 option was being ignored (which you have found!) A fix has been submitted to the Cura devs and I should think that it will be in the 4.1 release. In the meantime, if you are using either Linux or Windows (sorry, not OS X), you can try one of my releases that already incorporate the fix. I don't know how well the Mach3 flavour works as I don't think it sees a lot of attention so when you get to try it out, if you find any issues, please report them. You can find my releases at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0 They do not conflict with the Ultimaker releases.
  20. Hi, thanks for the file. I would recommend two changes, enable the Optimize Wall Print Order setting to reduce the amount of travel required and also set Max Comb Distance With No Retract to some non-zero value (10 or 20?). Hope this helps.
  21. Great, glad you have found a solution.
  22. Hello @nagygabor679, to help us diagnose the problem, please save a project file (File -> Save) and attach the resulting .3mf file to this thread. Then we can see the settings you are using. Thanks.
  23. Ah, I just noticed that your file doesn't contain any settings so I was using my settings. You should do File -> Save not File -> Export. This confuses Cura users new and old but the Cura devs do not seem very keen on making it obvious that to save a project file you need to save rather than export.
  24. The slicer assumes that the lines are rectangular in cross section (of course, this isn't true in reality but, then again, FFF printing is all one big approximation anyway). So for a line width of 0.4mm and a layer height of 0.3mm, 1mm of line needs 1 x 0.4 x 0.3 mm of filament which is 0.12mm^3. The filament dia is 1.75mm so that gives a cross section area of approx 2.4mm^2 so we need to extrude 0.12/2.4 = 0.05mm of filament for each mm of wall line length. Reality and intention diverge? Sorry, haven't a clue. I recommend that you use slic3r, then.
