Retraction Vertical Lift modifying printing height

[timcurtis67]

When I try adding say .6mm in my retraction vertical lift setting S3D adds that amount to my first layer z height? So if I'm wanting my first layer to be .3mm thick it actually makes it .9mm for the first layer. Is there a work around for this? I need Z retracts for this part I'm printing.

I'm using S3d 4.0.0

I'm using 4.0.1 and my first layers, even when using huge lifts like 1mm, I still have all my print moves printed at the correct height.

Are you seeing this in your prints or just the preview window's reporting of the Z position? I have noticed that when using retraction vertical lift along with preview by layer rathe than by line, the Z height reported is that of the last Z move in the layer, which would of course be the lifted height and not the actual layer's printed height.

I'm actually using 4.0.1. My issue is actually in the Gcode file. The first layer is trying to print at .9mm high. If I turn off the retraction vertical lift then my first later is at .3mm which is what I wanted.

It's got to be a bug? No one else noticed this yet?

I've not seen this happen to me. Can you attach your factory file?

[timcurtis67]

Yes I will attach it later tonight when I get home. Maybe I have something else set wrong?

In particular the posts made by me.

If you understand what I have posted, you'll understand there is no bug! And you have nothing set wrong.

Yeah it was my bad on that one. I looked father down in the gcode file and saw that the program starts out at the retract Z height and then drops to the correct height when the printing starts.

All is well.
