The percentages work fine for me. I use 100 for medium, 75 for fast and 200 for high quality.
If you want to make them specific to each quality option (high, medium, fast) you can export the FFF and add in the following line to each qualityconfigure group of tags.
These sections determine your autoQuality options
Code: Select all
<autoConfigureQuality name="Fast">
<layerHeight>0.3</layerHeight>
<topSolidLayers>3</topSolidLayers>
<bottomSolidLayers>3</bottomSolidLayers>
<skirtLayers>1</skirtLayers>
<infillPercentage>15</infillPercentage>
<supportInfillPercentage>25</supportInfillPercentage>
</autoConfigureQuality>
<autoConfigureQuality name="Medium">
<layerHeight>0.2</layerHeight>
<topSolidLayers>3</topSolidLayers>
<bottomSolidLayers>3</bottomSolidLayers>
<skirtLayers>1</skirtLayers>
<infillPercentage>20</infillPercentage>
<supportInfillPercentage>30</supportInfillPercentage>
</autoConfigureQuality>
<autoConfigureQuality name="High">
<layerHeight>0.1</layerHeight>
<topSolidLayers>4</topSolidLayers>
<bottomSolidLayers>4</bottomSolidLayers>
<skirtLayers>2</skirtLayers>
<infillPercentage>30</infillPercentage>
<supportInfillPercentage>40</supportInfillPercentage>
</autoConfigureQuality>
Add in this line to each section (filling in XX with your percentage value): <firstLayerHeightPercentage>XX</firstLayerHeightPercentage>
Code: Select all
<autoConfigureQuality name="Fast">
<firstLayerHeightPercentage>75</firstLayerHeightPercentage>
<layerHeight>0.3</layerHeight>
<topSolidLayers>3</topSolidLayers>
<bottomSolidLayers>3</bottomSolidLayers>
<skirtLayers>1</skirtLayers>
<infillPercentage>15</infillPercentage>
<supportInfillPercentage>25</supportInfillPercentage>
</autoConfigureQuality>
This code assigns the Fast quality option to print the first layer at 75% of your layer height.
