Has anyone had an issue with there being no retraction in Cura 2.7 when printing even though retraction is on? I'm getting great results otherwise but not having the filament retract is definitely going to fudge up the print. Also I wanted to know if Cura 2.7 has a gcode edit section like Simplify3D does where I can add a tool change script for a single nozzle dual extruder. {IF NEWTOOL=0} T0 ;Start tool switch 0{IF NEWTOOL=0} G1 X[next_position_x] Y[next_position_y] F[travel_speed] ; move to next printing location{IF NEWTOOL=0} G1 Z[next_position_z] F1002{IF NEWTOOL=0} G1 E0 F[toolchange_retract_speed] ; prime new tool{IF NEWTOOL=1} T1 ;Start tool switch 1{IF NEWTOOL=1} G1 X[next_position_x] Y[next_position_y] F[travel_speed] ; move to next printing location{IF NEWTOOL=1} G1 Z[next_position_z] F1002{IF NEWTOOL=1} G1 E0 F[toolchange_retract_speed] ; prime new toolG92 E0

So it turns out that updating to Cura 2.7 and then updating my .json file to reflect the 2.7 changes worked. I was able to get Cura to recognize not only my printer but the extruders as well. Thanks for all your help!

I'm using Cura 2.6.2. I guess I can update to Cura 2.7 then update the .json file and see if I have any luck with that.

A lot of the profiles are in that format. For example the Lulzbot Taz 6, and it shows up just fine. I don't understand why one definition would work in the older format, but another won't.

Thank you, turns out I needed a couple more. So now my json checks out, but unfortunately I still don't see it listed under "Add Printer" :( Are there any other reasons besides issues with the json that would prevent the printer from showing?

Thanks for the replies, I fixed it up to a point and then ran into a code blocker that I don't understand using the validation website: https://jsonlint.com/ Error: Parse error on line 210: ...default": 2 } } ---------------------^ Expecting '}', ',', got 'EOF' { "id": "davinci_jr", "version": 1, "name": "Da Vinci Jr. Mix", "inherits": "fdmprinter.json", "author": "Hacking Community", "manufacturer": "XYZware", "category": "Other", "file_formats": "text/x-gcode;application/x-stl-ascii;application/x-stl-binary;application/x-wavefront-obj", "platform": "davinci_jr_platform.stl", "machine_settings": { "machine_width": { "default": 150 }, "machine_depth": { "default": 150 }, "machine_height": { "default": 150 }, "machine_heated_bed": { "default": false }, "machine_center_is_zero": { "default": false }, "machine_extruder_trains": { "0": "custom_extruder_1", "1": "custom_extruder_2" }, "machine_nozzle_size": { "default": 0.4 }, "machine_nozzle_gantry_distance": { "default": 55 }, "machine_nozzle_heat_up_speed": { "default": 2.0 }, "machine_nozzle_cool_down_speed": { "default": 2.0 }, "material_diameter": { "default_value": 1.75 }, "machine_extruder_count": { "default_value": 1 }, "machine_gcode_flavor": { "default_value": "RepRap (Marlin/Sprinter)" }, "machine_start_gcode": { "default_value": "G21 ; set units to millimeters\nM107\nG90 ; use absolute coordinates\nG92 E0\nM82 ; use absolute distances for extrusion\nG1 F900.000 E-4.00000\nG92 E0\nG1 Z0.350 F6000.000\nG1 X3.000 Y31.000\nG1 F900.000 E4.00000\nG1 X5.000 Y31.000 F300.000 E4.46245\nG1 X5.000 Y131.000 E27.58519\nG1 X3.000 Y131.000 E28.04765\nG1 X3.000 Y32.250 E50.88011\nG1 F900.000 E46.88011\nG92 E0" }, "machine_end_gcode": { "default_value": "G92 E0\nM84" }, "machine_head_polygon": { "default_value": [ [-75, -18], [-75, 35], [18, 35], [18, -18] ] }, "overrides": { "layer_height": { "default": 0.2 }, "layer_height_0": { "default": 0.425, "visible": true }, "wall_line_count": { "default": 2, "visible": true }, "top_layers": { "default": 4, "visible": true }, "bottom_layers": { "default": 4, "visible": true }, "material_print_temperature": { "visible": true }, "material_bed_temperature": { "visible": true }, "material_diameter": { "default": 2.85, "visible": true }, "material_flow": { "visible": true }, "retraction_hop": { "default": 0.2 }, "speed_print": { "default": 50.0 }, "speed_wall": { "default": 30.0 }, "speed_wall_0": { "default": 30.0 }, "speed_wall_x": { "default": 30.0 }, "speed_topbottom": { "default": 50.0 }, "speed_support": { "default": 50.0 }, "speed_travel": { "default": 120.0 }, "speed_layer_0": { "default": 20.0 }, "skirt_speed": { "default": 15.0 }, "speed_slowdown_layers": { "default": 4 }, "infill_sparse_density": { "default": 20.0 }, "cool_fan_speed_min": { "default": 5.0 }, "cool_fan_speed_max": { "default": 75.0 }, "cool_fan_full_layer": { "default": 4, "visible": true }, "cool_min_layer_time": { "default": 5.0 }, "cool_min_layer_time_fan_speed_max": { "default": 15.0 }, "support_type": { "default": "None" }, "support_angle": { "default": 45.0, "visible": true }, "support_xy_distance": { "default": 1 }, "support_z_distance": { "default": 0.2 }, "support_top_distance": { "default": 0.2 }, "support_bottom_distance": { "default": 0.24 }, "support_pattern": { "default": "Lines" }, "support_infill_rate": { "default": 15, "visible": true }, "adhesion_type": { "default": "None" }, "skirt_minimal_length": { "default": 100.0 }, "raft_base_line_spacing": { "default": 2.0 }, "raft_base_thickness": { "default": 0.3 }, "raft_base_line_width": { "default": 2.0 }, "raft_base_speed": { "default": 15.0 }, "raft_interface_thickness": { "default": 0.24 }, "raft_interface_line_width": { "default": 0.6 }, "raft_airgap": { "default": 0.2 }, "raft_surface_layers": { "default": 2 } }

Hello, I'm trying to add my da vinci jr. 2.0 mix to the list of printers, but I can't get it to appear. Any ideas on what is causing the issue?
