Many times first layer is visibly perfect, but still there is slight overextrusion/elephants foot in couple of the latter layers. And to get perfectly flat underside without line marks, this slight overextrusion is even needed on the first layer (I'm talking about maybe 5%) so reducing 1st layer flow doesnt really make it better overall (2nd and 3rd layer flow could maybe be reduced though to fix it) One could maybe play with temperature settings layer by layer if maybe the heating effect of the buildplate plays a role or something, but a negative 2nd and 3rd layer HE would make everything easier and have more room for error. Another idea, there could be an experimental "chamfer" option that applies to models facing the build plate, like there is "make overhangs printable". Aside from maybe adhesion, chamfer is always more useful and prettier than an elephants foot.

When will this be fixed? It is a common 3D-printing related issue, that should be solvable in the slicing part, not as a chamfer in the model. (3D-printer should be able to print the model out as it is modeled) Isn't it just a copy-paste thing from the first layer HE behavior? Please add even 2nd, 3rd etc layer HE, or, if there could be an automatic chamfer calculated from the first layer HE, even better! I'm using values of -0.35 or more negative when the first layer is otherwise perfect and there's still a lot of elephants foot. If someone fancies to make a working mod, I'll paypal 40USD.

Thanks for answering and good luck fixing it. Fill gaps between walls seems like the feature that should be fixing this, but it doesn't do it consistently and everywhere. One thing I noticed, is that the problem goes away if I use a non-zero infill. I was trying to print walls only, but 0.01% infill is the new 0% I guess!

A very minor issue in Cura 4.5, but one that I haven't seen before just like this. Inner wall is not generated, in my case, for the topmost 6 layers. It is generated fine on other layers that have exactly same width features. Somehow it ceases existing when another feature in the layer ends.In picture, lowest layer has 3 parallel lines, topmost layers only 2. This is enough to cause a visible 0.25mm gap in the final print. This "bug" happens also elsewhere in the print. The following settings have no effect: -Print thin walls. -Top Layers/Top surface skin. -Fill gaps between walls. -Compensate Wall overlaps. Only way to solve this is to try to manually find suitable Line Width -settings for your print so that there are no visible gaps present. Of course this is not optimal. So pretty minor issue and there is a workaround but want to report this as I have high standards for my overall best slicer. This issue is similar, but not quite: ------------------------------

If you meant "compatible material diameter", this didn't have any effect. But I solved this by adding command M92 to the start of my gcode. (Reseting printer will return extrusion setting back to normal.) Info for other zmorph VX paste extruder users through Cura: Right now I'm using code M92 E11 in the start of gcode with a flow setting of 45%. This is with original 100ml syringe and 2mm nozzle. Thank you for answers!

The printer is Zmorph VX, haven't found settings for steps/mm in the firmware. Will try to add instruction in the start of the gcode to alter the steps/mm.

Hi all! I'm using a paste extruder with a 2mm nozzle. It doesn't have gearing so I'm needing about 2,5% of flow to get proper extrusion. Cura however counts under 5% flow as an error. I can make the first layer right by using Initial layer flow, but I'd be interested in making 3D prints with paste. Stuff I've tried: -Increasing compatible material diameter from machine settings. (Didn't do anything) -Setting "initial bottom layers" to 100 so every layer would be initial. (Turns out that there are multiple settings for "initial layers" that are independent, this setting was for shell and the flow setting is independent.) -Trying to find a way to disable error checking in Cura (no luck yet). So, any other route to achieve less extrusion with Cura? Thanks for the help!
