Duet 3 Zaxis and U axis motion

adhanabal

Hi,
As from my previous posts im making a SLS printer, My Z axis moves 0.1mm down in every layer, i want my U axis motor to go up 0.1mm on every layer change, what should i use in layer change script?

@adhanabal It could be simple, like:

G91 ; use relative moves
G1 U0.1
G90 ; use absolute moves

@o_lampe thank you

Why does the codebox look different after someone replied to my message? I've written three lines of "code" but now it's an unreadable single liner?!

@o_lampe looks fine to me here

@o_lampe looks okay to me, too. What platform and browser are you using?

I've noticed this as well. Reloading the page returns it to normal.

@o_lampe Hi it worked fine, i have one small query,
i want this layer change script to happen from 2nd layer, but when i put this code it works from the first layer itself, any idea to avoid it in the first layer?
im using simplyfi3d slicer.

@adhanabal if S3D allows it, you could try this:

if move.axes[2].userPosition>0.3
  G91 ; use relative moves
  G1 U0.1
  G90 ; use absolute moves

where I have assumed that 0.3 is greater than your first layer height but less then your second layer height. S3D may make the first layer height available to you as [first_layer_height] or something similar.
