Flow rate changes with layer height

Posted · Flow rate changes with layer height

Hi all,

I'm trying to diagnose print issues on a custom built printer, and I noticed that some areas of my print appear to be over-extruded, so I've been trying to find a way to visualise the calculated line cross-section. I found that I can visualise 'Flow' in cura, which is about as close as I can get. The problem is that flow is proportional to speed, so a fast section has a higher flow than areas of lower speed - I really need a visualisation that's independent of speed.


Anyway - what I noticed, is that as my layer count increase, so does my flow rate, even though the requested speed and line width are fixed. Why is this? I noticed on my other printer this doesn't happen, so there must be a setting in Cura that I've modified. Any ideas?









Line Width:



Overall Part - notice that the dark red sections are consistent with the over-extruded sections on my prints.



Thanks in Advance.

        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
