Flow Compensation Weighted by Current Flowrate

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

        (Sorry, was out of office when this released)

        This update is for...

        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.
