Hi,
Thanks for the reply, I have tried both already, I used the prusa calculator to get the best layer height, and that made no difference, or it did change the pattern position. the heated bed pattern would look different and it would fade further away the Z.
I go agree it has something to do with the layer height, but I am not really sure how to calculate the right layer height, unless I use one of this online calculator.also my leadscrew has a pitch of 2 that should make it really easy to divide.
