+# Voron V0 Cura Configuration
+Setup instructions for Cura and the Voron V0.
+
+<img alt="Cura Screenshot with Voron Test Cube" src="images/cura_screenshot.png" width="600px" />
+
+These instructions were tested on Linux and Cura 4.8, they should also work on MacOS/Windows.
+
+## Copy Configuration Folder
+Find the Cura `Configuration Folder`:
+ 1. Open Cura.
+ 2. Using the file menu, `Help -> Configuration Folder`
+ 3. The `Configuration Folder` will open in your file manager
+
+On Linux, the configuration folder is: `~/.config/cura/{cura_version}/`.
+
+Simply copy the contents `cura-config-folder` from this repository into the path above.
+
+## Adding Your Printer
+Creates an instance of your printer in Cura.
+
+Note, the Configuration Folder step above must be done before proceeding with the steps below.
+
+Add your printer to Cura:
+ 1. In the file menu, `Settings -> Printer -> Add Printer...`.
+ 2. Select, `A non-networked printer -> VoronDesign -> VORON V0`.
+ 3. Type a unique `Printer name` in the text box on the right.
+ 4. Click the `Add` button.
+ 5. Set the `G-code flavor` dropdown to `Marlin`
+ 6. Paste your Start G-code, see [Startup GCode](#Startup-GCode).
+ 7. Modify any settings, the defaults should be fine.
+ 8. Click the `Next` button.
+ 9. You should see your pinter in the dropdown.

+
+## Printer Definition
+Basic information about the printer is defined in:
+
+`{cura_config_folder}/definitions/voron0_120.def.json`
+
+## Print Platform 3D Model
+The 3D model is defined in:
+
+`{cura_config_folder}/meshes/V0_120mm_Bed.stl`
+
+The STL model is courtesy of [hartk1213](../../../PrusaSlicer/hartk1213/V0/Bed_Shape/Model/V0_120mm_Bed.stl).
+
+## Toolhead Definitions
+A set toolheads with various nozzle sizes:
+```
+{cura_config_folder}/variants/voron0_120_v6_0.25.inst.cfg
+{cura_config_folder}/variants/voron0_120_v6_0.30.inst.cfg
+{cura_config_folder}/variants/voron0_120_v6_0.40.inst.cfg
+{cura_config_folder}/variants/voron0_120_v6_0.50.inst.cfg
+{cura_config_folder}/variants/voron0_120_v6_0.60.inst.cfg
+{cura_config_folder}/variants/voron0_120_v6_0.80.inst.cfg
+```
+
+It is recommended to copy all toolheads, even if your printer only has one nozzle size available.
+
+These files can be easily modified if your extruder has unique sizing/requirements.
+
+Here is an example:
+```
+[general]
+name = V6 0.40mm
+version = 4
+definition = voron0_120
+
+[metadata]
+setting_version = 16
+type = variant
+hardware_type = nozzle
+
+[values]
+machine_nozzle_size = 0.4
+```
+
+## Startup GCode
+Start/End GCode runs before and after every print, it is unique to your specific printer.
+
+Here is an example for **Startup**:
+```
+G28                  ; home printer xyz
+G0 Y0 X40            ; go to tongue of print bed
+G1 Z0.2 F500.0       ; move bed to nozzle
+G92 E0.0             ; reset extruder
+G1 E4 F500.0         ; pre-purge prime LENGTH SHOULD MATCH YOUR PRINT_END RETRACT
+G1 X80 E10.0 F500.0  ; intro line 1
+G1 Y0.3              ; move in a little
+G1 X40 E10.0 F500.0  ; second line
+G92 E0.0             ; reset extruder
+G1 Z2.0              ; move nozzle to prevent scratch
+print_start
+```
+**NOTE:** The pre-purge prime (line 5) should match the length of retract in `PRINT_END` in
+your printer's `~/printer.cfg`.
+
+Usually the default `print_end` Stop GCode is enough.
