Posted · Flow Compensation Weighted by Current Flowrate

Dear comununity,

 

I made recently few test with the FlowTestTool from Stefan from CNCKitchen and got that way very well feedback what my printer configuration is capable of. As the test of Stefan and also mine reveals the real flow drops as flow rate increase, more or less proportional to the flow rate up to a certain point. So one way to tackle the problem could be to simply adjust the flow to compensate the typical underextrusion at higher flow rates. This can be done in Cura by adjusting each flow rate, but it gets messy as any structure (fill, wall ... flow) has not fixed flow rate per se - So I would assume I will end up with some overextrusion. Is there any option to fix that easly in Cura or is this the wrong way to handle this issue?

 

Here one of my measurements on my machine.

And here what I mean by a not fixed flow rate
