Retraction / Temperature Test Tower 8mm

Test tower of 8mm segments to test temperature, retraction distance, retraction speed e.t.c.

Just add/change the process every 8mm.

For each tower, I first start with broad settings then hone in with a second tower.
e.g First tower retracton layers 1, 2, 3, 4, 5, 6, 7, 8mm, then pick the best, which in my case was 3mm, so then went with layers 2.4, 2.6, 2.8, 3.0, 3.2, 3.4, 3.6, 3.8mm and chose the best setting from that.
