Vertical lift issue

Hello,
I'm using a custom profile for my Cetus 3D printer.
When I try to set up "Retraction Vertical Lift" of 1 mm, the Z axis starts with a retraction beyond the movement stroke, causing a loss of the stepper motor position.

This is the generated G code of the starting sequence:

G92 E0
; RETRACTION
G1 E-35.0000 F36000
G1 Z1.000 F1002
; process Process1
; layer 1, Z = -182.625

As you can see, the first Z movement is G1 Z1, but the Z ranges from 0 to -182.8 mm, (positive values are out of the Z range).

I've tried to insert a G0 Z-10 on the first script, but the result is still the same:

G0 Z-10
G92 E0
; RETRACTION
G1 E-35.0000 F36000
G1 Z1.000 F1002
; process Process1
; layer 1, Z = -182.625

Any suggestion ?
Thank you very much.

Regards,
Gabriele.

Re: Vertical lift issue

Is there any command like M82 / M83, than there is perhaps a missmatch with "absolute" and "relative" distances.

Have also a look to Tab GCode, left side, 2. checkbox. Uncheck it.
