I'm having a Prusa i3 derivative printer with a capacitive sensor for the z-axis. It switches a tiny bit before the nozzle hits the print bed and hence needs a z-offset to be configured.
In Slic3r I have configured the z-offset to
-0.1 on the General page of the Printer Settings, but currently I'm evaluating Cura and can't find such a setting. Slic3r seems to apply this setting directly to the generated z-values in the g-code, so it does not use a short version at the beginning of the g-code. My current (except of the auto-bed-leveling part default) g-code:
G28 ;Home G29 ; auto-bed-leveling G1 Z15.0 F6000 ;Move the platform down 15mm G92 E0 G1 F200 E3 G92 E0
Is there a way to configure Cura, e.g. using the Start Gcode options, to apply the z-offset?
For Cura 3.1(?)+:
Install the plugin: Menu / Plugins / Browse Plugins... / scroll to "Z Offset plugin" <-- Install
Configure the setting:
Printer Profile / Print Setup / Build Plate Adhesion / Z Offset
- set positive value for nozzle liftup
- set negative value to bring nozzle lower for first layer (like -0.1 for your wanted scenario)
