underextrusion after a travel move is a different problem

Solved the issue for another person. Before - After

Infill Fan Speed Override does not cause any problems. This bug is exclusive to Support Fan Speed Override.

Hello everybody, I am using @burtoogle's most recent Cura build (20190826). I noticed that enabling the Support Fan Speed Override inhibits slicing of the model. When the fan speed override is enabled, the slicing progress bar moves to about 50% and stays there for a moment, then it falls back to 0% and gets stuck there. Disabling the fan speed override restores function. What model is being sliced appears to not be of importance. Please find attached my project file and the STL with which I noticed this error. Nimble_Mockup_left.3mf Nimble_Mockup_left.stl

I can't believe how quickly you figure these things out!

I posted the stl in a comment further up, called "cage.stl" along with the gcode and project file.

@burtoogle, it is a different STL that I was printing today. After the installation of your newest build got rid of the useless travels in the previous project, some of them have returned in this new one, albeit far fewer now. Finding them in the gcode is fiddly, but fortunately the first one occurs right in the first layer at line 1968. Since I was around while my i3 Mega was printing this part, I could also observe that this was not the only travel during the print that seemed to occur for no reason at all. I tried to think of something that could be causing this issue, but I am quite frankly stumped. I know virtually nothing about the inner workings of slicing software. I wish I could give you a more detailed description and maybe some hints as to what the cause could be. Thank you very much for your assistance and all your help so far!

@burtoogle, this has certainly solved the issue with about 95% of travels, but there are still some showing up randomly near the end of some layers. I can't figure out if there is any pattern to it or anything like that. I can definitely see though that there is no extrusion involved in these moves, neither in practice nor in the gcode. An example of this you can see in this gcode right at the end of the first layer. Sliced with your newest Cura build. Cage.gcode Cage.stl Cage.3mf

I'm already using your build anyhow 🙂

@burtoogle, that seems to have done the trick! The print is about half way done and I couldn't observe any unnecessary travels so far. The quality of the object already looks far better than all my previous attempts. What caused this issue? How can I avoid it?

@burtoogle, could this be about a plugin that may cause problems? I've been trying to make sense of the error, but I can't figure out what 'key' could possibly mean. As for combing, I'd prefer to find a way to keep it turned off as it has mostly been causing problems in the past.

done @burtoogle 😊

Hello everyone, since updating to the latest Cura version, I have problems with completely unnecessary travel moves at the end of some layers. This causes excessive oozing and greatly impacts the quality of my prints! I have located the corresponding lines in the G-Code and cannot find any reasons for these travel moves to exist. Please find the STL and gcode attached. The first example of the travel moves occurs in layer 2 in lines 9978 to 9981 of the gcode. What causes this problem and how can I solve it?

Hello everyone, it would be wonderful if "Infill Layer Thickness" could also round up to the next multiple of the layer thickness, the same way the "Support Z Distance" does. That way it wouldn't need to be changed with every print and one could set it once and never worry about it again. The same way that many people have set the "Support Z Distance" to a value like "0.165" to always have the Z distance be a multiple of the layer thickness until 0.17mm layer height, at which the "Support Z Distance" automatically starts being equal to the layer height. Currently, the "Infill Layer Thickness" is forbidden to be smaller than the Layer height and only rounds down. Thank you everyone for your consideration 🙂

It is running like a charm and gyroid infill now prints flawlessly, no matter at what speed! Thank you very much for that 🙂 If I have ideas for improvement, would you like me to pitch those to you or should I post these here, as usual?
