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?

 

 

Flow:

Line Width:

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

Thanks in Advance.
