Directions and files needed to set up a RailCore II in CURA and display the build plate are outlined below. These instructions apply to Windows 10 and Cura 3.6, but can be easily adapted to other platforms. Step 1: Copy "railcore300zl.def.json" to "C:\Program Files\Ultimaker Cura 3.6\resources\definitions" Copy "railcorezl_extruder_0.def.json" to "C:\Program Files\Ultimaker Cura 3.6\resources\extruders" Copy "railcorebedcentered.stl" to "C:\Program Files\Ultimaker Cura 3.6\resources\meshes" Step 2: Open CURA and go to Add Printer. Select "Custom" and then RailCoreII ZL Step 3: Edit your Start and End G-Code (Examples Below) Start G-Code: G28 ; Home All G21 ; metric values G90 ; absolute positioning M82 ; set extruder to absolute mode M107 ; start with the fan off G92 E0 ; zero the extruded length End G-Code: G92 E1 ; Retract Filament G1 E-1 F300 ; Retract Filament G91 ; Relative Coordinates G1 Z10 F6000 ; Move Z out of the way M104 S0 ; Turn off Heat bed and extruder M140 S0 ; Turn off Heat bed and extruder G1 X290 Y290 F9000 ; move print head to back left corner M84 ; turn off Steppers Step 4: Adjust printer X, Y, Z to what you have set in the Duet config.g Step 5: Once that is all working, use Notepad++ to edit "railcore300zl.def.json" file "platform_offset" coordinates to get an exact line up of the build plate under the CURA build area. The format is X, Z, Y. If your build area is 300x300 and X lines up with the left side of the built plate you can use "platform_offset": [19.5, 0, 0], Step 6: There is a second Bed STL that contains a logo if you would like to use it, copy it to the meshes directory, change the "platform" file name in the json
