Hi, thanks for bringing up this topic... I checkt it actually measured it and found that the axis are not 90°. From what I measured on a distance of appr. 80mm I have 1.3mm deviation from 90° angle of my old scool triangle roller.
Wow. I did not expect this. What can be done to solve this.
Look straight down from above the printer - do the two rods going through the head look perpendicular?
Push the head around with your hand to the center of each of the 4 sides. Do the end blocks seem to stop at the same time or is one block offset?
