  1. I can not get rid of this bug, even though i probably changed every single setting i can. where the layers start, too much filament is extruded most of the time. According 3MF file: LayerUpwards.3mf Config: BugLayer.curaprofile Another example is this: Where the z seam should be, too much filament is placed. Also on every new part of the same layer, there remains an excess amount. I have Coasting tuned already. Is there like an option to increse coasting for only the first line of a part or so?
  2. I do not understand why on some prints, the layers deform upwards where the z seam is. on other prints, this is not the case: even though this little thing was printed at very high speeds. The first print is simply a cylinder, the 3MF here: LayerUpwards.3mf My configuration here: BugLayer.curaprofile I played around with Wipe Distances and Coasting but i simply can not resolve this. Any idea which setting in my profile could be causing this? Printed on a Hypercube Evolution with Bowden setup.
  3. @gr5 Thanks for the response! I have a github account and just created a bugreport. Good hint!
  4. even if i set skin overlap percentage to 80%, i still have the same issue: The damn bottom lines just do not attach to the walls on the right side. I has retract before skin enabled, disabled this and this also brought no improvement. I summed up the problems in a more organized way in this post: As this is apparently a bug in cura and should therefore be made easily accessible to more people.
  5. Dear Community, I am experimenting on the bridgeing settings for a while now. Some things may be due to me not having found a perfect configuration yet, others are defenite bugs: Bug 1 When selecting Wall Ordering from inside to outside and the print walls are thinner than the wall width (wall count * nozzlediameter) selected, bridgeing will start in mid-air, causing the print to fail completely (overexaggerated example with 8 walls): I see no reason why this could be any good, and why one would not implement a setting where for bridges, wall order from outside to inside is always selected. Bug 2) With wall ordering from outside to inside, the wall lines of the bridge are printed fine (as they have supportive "real" wall lines from the outside). However, the overhang (bridge without wall) fails on one side: This is printed with 4 walls. To make sure no other setting is causing this, i completely disabled coasting and linear advance, and set an infill overlap percentage of 50.0% Still, the bridges do not connect on one side, but perfectly on the other. From the layer view in cura, i can not see why the left wall would work while the right one does not. Bringing the wall count down to 2 for this model will solve the problem. But i do not want to print only this model fine, but any model. Normally i use many walls to hide infill better and give stabilty, and using bridgeing is much worse than not doing so. I hope maybe Bug2 is caused by my profile and can be solved somehow (without getting the wall count down) I appreciate any response! bridgeing_bug2.3mf bridgeing_bug1.3mf
  6. Setting the walls to 2 for this model indeed helped to print the bridge at it is supposed to be printed. However, printing with few walls is no option for me, i usually set the wall count to 5 so i have sturdy prints and no infill showing through. In this case, for every print that has some wall thinner than 4 nozzle widths, briding fails completely. is this the case for everybody? Can't i get this specific print to work without having to set the wall count down? I do not even understand why with 4 walls as in the picture, the retraction happens too early, before the nozzle reaches the yellow wall lines. From the gcode it looks normal:
  7. Lastly: Even with printing from outside to the inside, bridges are still REALLY bad, much worse then without bridgeing enabled. The shell layers arte printed fine. When starting with the top-layers that build the actual bridge, always one one side threre is a retraction BEFORE the nozzle reaches the bridge wall. This causes one side of the bridge top to be in mid-air, which obviously is really bad: To find out, where this is coming from, i first set bridge co3asting to 0, which did not change a thing. Then i set overall coasting to 0, still the same. Also my linear advance is disabled at the moment. What is causing this? BridgeBug_2.3mf
  8. Things i noticed: When using my normal "Inside to outside" Wall ordering, the first lines of bridges are always printed into the air: The more walls i set, the more in air the first green line starts. When printing with different wall ordering, things are a lot better. In my opinion it should be implemented that for bridge layers, wall printing always happens from outside to inside. I see no scenario where printing into the air as in my screenshot would be good.
  9. Thanks so much for the answers. Still, i just can not figure out bridgeing settings that give me better quality than just brideging disabled. Here, first an object with bridgeingh settings as in my config file before. Secondly the same object printed without bridgeing, but with a gcode modifier to reduce printing speed to 20 at layer where the bridge is. The latter is much better. 3MF of the bridgeing on file also included. CFFFP_Servohalter.3mf
  10. Hey Greg, thanks for testing. I already use Lines as Bottom pattern as is also expected this to cause a problem. Here the 3MF: BridgeBug.3mf
  11. So as a summary, the 0 point should not be the point where all axis are at the endstop (the minimum position every axis can reach in my case) BUT at the corner of the heated bed?
  12. I noticed my bridges always suck, even with the 'best' parameters. Upon closer 9inspection, i notices that the first element of the bridge is just printed in mid-air. It is the first thing Cura does in this layer: Start with the INNER part of the bridge, print it in mid-aior, then go outwards, then the normal walls. Why is this? What can i do about it? bridgeingBug.curaprofile
  13. Dear Community, When trying to max out my print bed, i realized that my printer can print next to the bed. In my machine, the traves area is much larger than the bed area. In 'printer settings', i can only set the Printer size, defining the maximum travel area. How i can limit this to only the print bed area? I do not want to use M206, because some of my Macros (e.g. Change of Filament) require the printhead to be next to the printing bed. I just want to add forbidden zones in Cura Slicer.
  14. I put so much effort in this post. This is my first problem with cura in years. i'd be really happy to get any response.
  15. I built a Hypercube Evo with a Duet Wifi Board. Cura has always been my favorite slicer - I mostly copied the Ultimaker S5 profile. I printed a beautiful Benchy but noticed some "wobble" at the back. Like z-wobble, but in Y-direction. Then i printed a hollow calibration cube - the same wobble appeared. Only in Y direction (Xmin and Xmax walls). It looks like a mechanical problem - BUT it is only on the outside walls. I wanted to see if it is a Slicer problem, so i sliced the same Cube with S3D... And the wobble is completely gone. First image shows outside wall with wobble, Second one the corresponding inside wall without wobble. Last image is the outside wall comparaision between S3D (left) und Cura (right). HCEvo.curaprofile
