4 Cube Retraction Calibration

thingiverse

I used this series of precision-cut cubes to fine-tune retraction for my large-scale deltaprintr machine. The cubes are strategically placed at precise spacings, measuring 10mm, 20mm, and 40mm apart from one another. Due to the extensive length of the bowden extruder, I began with a modest setting of 2mm of retraction and accelerated to a speed of 30mm per second. I continued to adjust the parameters until I reached an optimal level of 4.0 mm of retraction and elevated it to a speed of 55 mm per second, at which point everything fell into place seamlessly.
