Thank you! I'll give that a shot right now. In black and white 1/32 stepping makes me think that it's capable of more precise movement there fore capable of higher quality prints. Is the hardware...
View ArticleRe: Printhead and bed movements off
On a Cartesian machine 1/32 is over kill in my view. Due to the way steppers work, you don't get increased accuracy, just lower noise (steppers do not move on every micro step) It also limits the max...
