The Advanced Retraction Test allows the user to tune retraction while taking into account variable distance.

This uses 4 pillars that start at 5mm tall and increments by 5mm. 5, 10, 15 and 20mm tall. This allows you to change retraction speed and or distance at specific z heights and see how they change a variable distances. The closest pillar is 10mm from the center pillar and then 15mm, 20mm and 25mm.

The center pillar test for stringing on parts with very close walls.

Example retraction test.

Using the script ChangatZheight we will insert the script every 5mm exept for the last pillar which we will change at 18mm to squeeze in one final test. Once you have determined you optimal range you can get more granular with your values.

Script 1 ChangatZheight

@0mm

Set retraction speed to 25mms

Set retraction distance to omm

Script 2 ChangatZheight

@5mm

Set retraction speed to 25mms

Set retraction distance to 2mm

Script 3 ChangatZheight

@10mm

Set retraction speed to 25mms

Set retraction distance to 4mm

Script 4 ChangatZheight

@15mm

Set retraction speed to 25mms

Set retraction distance to 6mm

Script 5 ChangatZheight

@18mm

Set retraction speed to 25mms

Set retraction distance to 8mm

Enjoy!
