Zip of def files.zip Instructions for adding these files to cura are available online. Open Cura: Help/Show Configuration Folder. I changed the platform offset in vscode to 33, -7, 17 to align in cura.

So sorry, I have not been checking this thread. Did you get software? https://support.smart3d.tech/hc/en-us/articles/360021232131-KODAK-Portrait-Reflashing-the-Smoothie There is a link there for flashing the raspberry pi. It's a project. Micro SD cards are accessed by removing bottom panel etc.

Agreed. Thx Greg

Thanx, I had the G28 Y code in there because I had not learned to put the delay for stepper motors to turn off. I was doing the "place item (magnet) in print" and the Y axis slide during the process so rehoming the Y axis fixed that. Don't know why but when I cut the G28 Y out, the problem went away. Oddly, I have done several successful prints with rehoming the Y but in the end putting a delay in stepper motor deactivation was the real fix. Just starting with the Gcode thing so I appreciate the feedback.

Can someone see why I get this Z movement after Pause? I have done this a few times with success but am unable to find what is causing the Z axis to move down to the bed and then the Head collides with the print. ;TYPE:CUSTOM ;added code by post processing ;script: PauseAtHeight.py ;current layer: 107 M83 ; switch to relative E values for any needed retraction G1 F1500 E-1 G1 F300 Z22.6 ; move up a millimeter to get out of the way G1 F9000 X222 Y222 M104 S200 ; standby temperature M117 2 M18 S1800 ; Set the disarm timeout M0 ; Do the actual pause G28 Y M109 S210 ; resume temperature G1 F1500 E1 G1 F199.998 E1; Extra extrude after the unpause G1 F1500 E-1 G1 F9000 X145.046 Y144.755 G1 F300 Z21.6 ; move back down to resume height G1 F1500 E1 G1 F2139.4 ; restore extrusion feedrate M82 ; switch back to absolute E values G92 E704.4168 ;LAYER:107 ;TYPE:WALL-INNER ;MESH:Cage3B.stl G3 X144.459 Y145.013 I-0.764 J-0.943 E704.43832 F1069 G1 X143.691 Y145.016 E704.46386

I just read this and, dang, I forgot that I printed a temp cal tower. I have a new file without it here. I will try to re-read this today but I already started the 2nd instance of the printer in Cura. -Also, u r right.. there is no start ugcode for either nozzle. -Also, either extruder (but not both) can be disabled in cura in the "Prepare" stage. Only the enabled extruder is heated with Kodak ( and now Cure with your {initial_extruder_nr} fix. Thanx so much! KP_Cal gcode 2.gcode

Boom! CalGcode1.gcode KP_Cal gcode 1.gcode

Thanx Greg! KodakCalCube.3mf

Hey Greg, 3mf attached above. Are you still there? Thanx

The Kodak uses that to center (ish) the head, brings z axis up fast to @ 10mm then slow til it pushes nozzle1 up slightly to confirm z offset. The head(s) are cylindrically constrained and signal as soon as plate pushes it up. Only Extruder1 is used for this so when using ext2 it switches for Zoffset on every print. Thanx again! Cal gcode 1.3mf

A Little Progress! I put {initial_extruder_nr} as you suggested and it allowed extruder2 to print. YAY! Worse case I can struggle forward from here. I hope it's not too much trouble to look at the gcode I last generated in text to see what was going on. My printer home's when turned on (firmware I'm sure) -Then changes to Extruder2 (as this file is on extruder2) -slowly creeps to center (maybe the mm/min vs mm/sec you spoke of) -heats bed/nozzle (i turned bed off for this test) -changes back to nozzle1 -homes again -then back to center -bed raises and bumps extruder1 to check Z offset -switch back to extruder2 -creeps again to center -prints gcode Also offsets are not right. prints off center unless i move the stl on the bed as I did here. ;FLAVOR:Marlin ;TIME:79 ;Filament used: 0m, 0.0567741m ;Layer height: 0.2 ;MINX:58.9 ;MINY:76.4 ;MINZ:0.3 ;MAXX:116.1 ;MAXY:133.6 ;MAXZ:0.5 ;Generated with Cura_SteamEngine 5.2.1 T1 M104 S220 M105 M109 S220 M82 ;absolute extrusion mode ;kodak begin G21 G90 M82 M107 G28 T0 G92 E0.0 G1 X100 Y100 F3000 T1 ;kodak begin G92 E0 G92 E0 G1 F2400 E-5 ;LAYER_COUNT:2 ;LAYER:0 M107 M204 S3000 G0 X60.294 Y77.171 Z0.3 M204 S2250 ;TYPE:SKIRT

Cura does read things that are in curly brackets and will put the correct number in when the gcode is created. I had a '76 wing. Great highway bike but short trips had me cleaning the carb needles a bunch. I now ride a triumph sprint and suffer from a similar old-man bar fatigue. Short trips are a joy tho : )

The Kodak Printer has no such xyz readouts or controls to move x,y. (core xy machine) The Z starts at the bottom and you can bump it up by preset increments (like 50mm) until you get close to the heads (20mm or so) and then no more. It is not an open source, user interactive machine at all. I was able to print an X in a square outline and print it out on extruder 1. (there are 2) I measured the distance to center of X to center of build plate at 40mm on the x axis. In Cura, I took the 40mm and changed the Machine/extruder "Nozzle offset x" from 0 to 40 for extruder1 and from -40 to 0 on extruder2 and that worked perfectly, I then changed the value of the "platform_offset": [-6, -7, 17] to 33,-7,17 to line up the stl of the kodak build plate mesh and that worked as well. Prints centered via cura's center option print in the center now so that is done. I went to print extruder2 to check but.....after auto-home from start gcode printer switches to extruder2 and preheats extruder2 and bed. Then the printer changes heads and tries to print with the unheated extruder1 I opened up the "fdmprinter" json from the kodak software pkg and compared it to the cura fdmprinter json looking for the differences and there are many. Any Idea why the extruder confusion? It seemed to know that the file was for ext2 and then switched back after heat up. Still would like to know why "overrides" in the kodak json definitions file are not used by cura. If you know, please share. I appreciate the help (luv the bike!)

Thanx for the quick reply. I apologize that I did not research enough to see previous queries on this topic. I went to try the suggestions but these controls are unavailable. I tried to connect do the printer via usb to control manually but noooooooo. I attempted to operate the printer directly with Chrome Gcode sender but also no. Cura built the Kodak slicer and I am able to operate with it on an older mac but it is painful to go between stations to design, slice and print. I wonder why Cura does not load the values in the definitions file for "overrides" like line 29 " "material_diameter": {"default_value": 1.75 }. Perhaps it is not also using the offset in line 38. Can I simply print an "X" at center of a mesh, center it in the Cura slicer, print it, measure distance of print to center of actual built plate, and enter those offset values in the machine setting extruder x,y values within Cura app? Thanx

I have the Kodak printer and am on Mac OS 13, looking to get it to work with Cura (5.2.1). I was able to put the definition, extruder, mesh files in to the configuration folder and I am able to print BUT... -The .stl file for the mesh does not align with the build plate presented by Cura. -More importantly, files sliced on the right crash the print head off the build plate when printing. I was able to move the .stl presented from mesh to align with the Cura platform via mods in the kodak definition file in VSC "platform_offset": [-6, -7, 17], to [33, -7, 17] But the print still crashes. I tried to change "false" to "true" in overrides as below and default value to "0" and back again with no change. "machine_use_extruder_offset_to_offset_coords": { "default_value": true }, "machine_origin_offset_x": { "default_value": -40 } I also don't know why the values for "material diameter" line 29 are not updated to the machine settings. I corrected them from 2.85 in Cura app { "version": 2, "name": "KODAK Portrait2", "inherits": "fdmprinter", "metadata": { "visible": true, "author": "KODAK", "manufacturer": "KODAK", "category": "KODAK", "file_formats": "text/x-gcode", "platform": "kodak_portrait_platform.stl", "has_materials": true, "preferred_material": "kodak_pla", "has_machine_quality": true, "preferred_quality_type": "normal", "platform_offset": [-6, -7, 17], "machine_extruder_trains": { "0": "kodak_portrait_1st", "1": "kodak_portrait_2nd" }, "supports_usb_connection": true }, "overrides": { "machine_start_gcode": { "default_value": ";kodak begin\nG21\nG90\nM82\nM107\nG28\nT0\nG92 E0.0\nG1 X100 Y100 F3000\n;kodak begin" }, "machine_end_gcode": { "default_value": ";kodak end\nG91\nG1 E-4 F300\nG28\nG90\nM140 S0\nM104 T1 S0\nM104 T0 S0\n;kodak end" }, "machine_name": { "default_value": "KODAK Portrait2" }, "material_diameter": {"default_value": 1.75 }, "machine_extruder_count": { "default_value": 2 }, "machine_heated_bed": { "default_value": true }, "machine_height": { "default_value": 235 }, "machine_depth": { "default_value": 210 }, "machine_width": { "default_value": 255 }, "layer_height": { "default_value": 0.2 }, "speed_print": { "default_value": 75 }, "machine_use_extruder_offset_to_offset_coords": { "default_value": true }, "machine_origin_offset_x": { "default_value": -40 } } } I'm new to coding and not brand new to 3d printing but have no idea how to proceed. Thx

Mac or PC? I have found on Mac placing the files as directed in the readme file does not work. It is possible that I am not doing it correctly as I am a newbee at Cura. When I place the files in Cura/Content........Resources/definitions etc folders, my printer/extruders/mesh shows up.

Update on the RawMouse install. All axes work except when spacemouse overall speed is set below a certain threshold. : )

Awesome! Spacemouse wireless working with your RawMouse plugin. Only up/down, left/right, and Zoom are working but it's soooooooo much easier. Thanx burtoogle!
