Kodak Portrait

Despite the name, it's 3d. Despite the vendor/label, it's surprisingly mod-friendly

General notes/instructions

  • the stock print surface is a mirror. don't print PET-G (and possibly ABS?) directly on it. they have a tendency to bond with glass too strongly.
  • the stock nozzles aren't hardened. don't print filament with additives using them.
  • the printer uses 12V PSU, so heating the print surface takes a while
  • the printer uses the hotend on the right as a Z probe
  • the printer has been klipperified (WIP)! stock slicer won't work anymore!
  • password for root user is, for now, identical to hswaw wifi password
  • don't do Nix things when a print is in progress; overloads the RPI and makes klipper unhappy
  • takes a while to boot; when it's done you should see KlipperScreen interface

profile(s) for slicer(s) (WIP)


Very rudimentary config. Works, including hotend swaps, but is a bit slow and messy klipper-kodak-portrait-bundle.ini (haven't tested with just a single hotend in use, may misbehave, whoops)

Hardware documentation

  • standard raspberry pi 3b
  • standard smoothieboard v1
  • LED driver board connected to the rpi (generic 4pin - rgb+ground - pwm-driven ledstrip)
  • removed most of hotglue as it did not hold the connectors anymore anyway

Raspberry PI

Nothing really surprising here


Almost all connected cables are labeled; motor connector labels are taken mostly from configuration file, as they were only labeled M{1..5}

Stock smoothieware config:

  • HE0: heater for extruder 1
  • HE1: heater for extruder 2
  • HBR: heatbed heater
  • FC: M106/M107 Fan; extruder fan(s?)
  • FA: M42/M43 Fan; “ambient fan”? possibly the exhaust/filter fan

Config also references the two free endsop inputs as filament runout sensors, but neither sensors nor cables are present.

Power supply

Again, nothing really surprising here. Just a “Mean Well RSP-320-12” and a stepdown board providing 5V to rpi and smoothie


  • solve filament/power switch access
    • moving bambu to the other shelf helped a bit
    • fully extending slide-out shelf should actually solve this.
  • obtain second print surface

  • hardware documentation (what's connected where and how)
  • calibration, at least to the extent reasonable before we have proper slicer profiles
  • general UI/UX:
    • klipperscreen running in cage on the touchscreen
    • fluidd for webui
    • moonraker accessible over network for slicers
  • fix camera/audio under nixos

Preliminary findings

  • controlled with a normal rpi3 + smoothieboard combo
  • screen is connected over hdmi (+ usb for touch?), 800×480 res
  • camera uses the camera interface
  • one usb port is used for connecting to smoothieboard, one is routed to the outside, and one is free
  • there's a speaker!
  • doesn't appear to do anything fancy to lock-out mods
  • disassembly, at least for getting to the electronics compartment is trivial:
    1. unscrew two screws on left and right (4 total) that hold the bottom panel (regular hex bit)
    2. unscrew the feet (next size larger hex bit)
    3. unscrew 4 screws on the *sides* of the metal box holding the electronics (the ones that you see in front of you hold the fans)
    4. remember to detach the fans when opening the box

no longer relevant

these items referred to stock software/firmware, leaving them here for future reference for anyone from the wider internets stumbling upon this page

  • ran raspbian by default
  • didn't complain about creating /root/.ssh/authorized_keys
  • on running system, root filesystem is by-default mounted readonly, which is a Good Choice™ on an rpi with sd card; mount -o remount,rw / and later mount -o remount,ro / work as expected.
  • password for pi user is, for now, identical to hswaw wifi password, passwordless sudo is enabled.
  • the printer runs its control panel using chromium pointed at a webserver running locally. that's listening on all interfaces. try http://printers-ip-address:8888/home (check setup → connectivity → network)

“stock” slicer (really just an old cura, reskinned), stock firmware images:

Many resources about the printer from, apparently, its actual vendor:


Would prefer to keep hardware mostly unmodified, except for following

  • replace the e3d v6 with e3d revo (and obxidian nozzles) which is almost a drop-in replacement
  • replace the 12V PSU with 24V
  • add filament runout sensors
  • buy angled cables and rotate the screen proper way round.
  • accelerometer for input shaping
  • brushes for automated nozzle cleaning
