Ironing Pattern Calibration

Needs: Flow Temperature

You need to do the filament flow calibration and the bridge flow ratio before this one. It's better if you have done the filament temperature calibration as well.

This calibration method will print test samples with various levels of above-bridge flow ratio, between 100 and 125. Choose the lowest value on which the top surface is smooth without rough "holes". Begin with the above-bridge calibraiton.

If the above-bridge calibration is not conclusive (same holes on all samples), then set it to 110% and use the top flow calibration. This setting is a bit more unpredictable so it's best to not move it far away from 100%.

Results

Example:


Not flat	Not flat	Not flat	Flat	Flat

Here, we can see that artifacts exist until the above-bridge flow was set to 115. It was flat from the flow calibration, if it's not now, it's because the bridges below the top surfaces are dropping a bit, and so it leaves more volume to fill afterwards. Here, 115 should be enough, but 120 is a more safe bet.

Notes

This test set the setting "Complete individual objects" to true, so you may want to reset your print settings afterwards
