Fewer “busy” screens, and clearer problems

• Uploads no longer bounce with “busy”. Phone and app uploads (the QR page, Touchpix and similar apps) used to be refused for the whole time a photo was being processed. They now wait in line behind it — up to six at a time — and the guest sees their place in the queue.
• A step that gets stuck no longer leaves the guest on “Plotting…” for ever. If an AI, line-art or G-code step does not finish in a reasonable time, the booth now shows a clear error and sends the usual alert so the session can recover.
• Plotter presets draw faster: “Smart join strokes” is now switched on by default. It joins line ends that touch so the pen lifts less often. Projects you already have keep their saved setting — tick it on the G-code node to use it.
• Booths now send their diagnostic logs to PromptPhotoBooth automatically, about every six hours, so support can see what happened without you having to send them. Guest names and email addresses are removed first, logs are visible only to our staff, and they are deleted after 30 days. Contact us if you would like this turned off for a booth.
• Updating from Settings is clearer. If the installer cannot start or fails, the booth now shows why instead of waiting for several minutes, and the update log is kept after the restart so it can be read afterwards.
• Wi-Fi settings: the network you are connected to now shows as connected even when several routers share the same name (common in warehouses and venues), instead of offering “Connect” again.
• Settings → Booth: the address shown for connecting an external upload app no longer includes the extra “/public-upload/” part.

Add a node and it connects itself

• New autowire for the node editor — when you add a node to a flow that already has steps, you are now asked whether to connect it automatically or place it yourself. Automatic placement puts the node where it belongs in the booth flow (a camera never lands before the start screen), links it in, and keeps your “go back to the start” loops intact.
• It wires the data too — photos and other media from the steps before the new node are connected to its inputs, photo-strip and GIF composers fill their photo slots in order, and screens after an effect (a viewer, say) now show the effect’s result instead of the original photo.
• Every automatic change tells you where the node went and has an Undo button. Tick “Remember my choice” to stop being asked, hold Shift while adding to do the opposite for a single node, and reset it from the bottom of the palette. It works from both the palette and the right-click menu.
• Simple (steps) mode uses the same wiring: a new step gets its main input connected, optional inputs such as Reference or Logo are left for you, and later steps pick up the new result.
• Sensors, LEDs, timeouts and the specialist mosaic and mural nodes have no fixed place in a flow, so autowire adds them without changing how your flow is connected.
• Plotter: the default minimum stroke length is back to 0. The 0.6 mm dust filter introduced in 1.0.210 could delete real line pieces on centerline art, giving choppy, incomplete drawings.

Surveys for your guests

• New Survey node — build a form right in the editor. Up to 12 questions: short or long text, email, phone, number, single or multiple choice, a 1–5 star rating, a 0–10 score, or yes/no. Mark each question required or optional.
• Guests can answer on the booth screen, one question at a time, using the on-screen keyboard — with a progress bar, large touch targets and an optional “Skip survey”.
• In the live-caricature QR flow, the survey now comes right after the optional name-and-message form and before the photo. It drops out on its own if you close the survey, and it works even if the Survey node is not wired into your flow.
• Guests can also take the survey on their own phone: the node gives you a public link to put behind a QR code, and open surveys are offered on the event’s gallery page.
• Every answer syncs to the event on promptphotobooth.com. Browse the responses, close or reopen a survey, and export everything to CSV from the event’s page in your account. Answers are also saved as a CSV in the project folder.
• Survey answers are never lost on flaky venue WiFi — they wait on the booth and are delivered when the connection returns, without ever creating duplicates.

Watch the plotter draw, and faster plots

• New Plotter Live View — show the drawing being inked on the booth screen at the pace the plotter is really drawing, with a pen cursor and a progress bar. Wire the plotter’s G-code into it and place it after the Plotter node.
• New Smart Join Strokes option for plotting — line-art strokes that carry on from one another are drawn as one line, so the pen lifts far less often. On our test portraits that is around 30% fewer pen lifts. Junctions where several lines meet are left alone, and it is off until you switch it on.
• Tiny stray marks are now dropped after near-closed outlines have been closed, instead of before. Dust that cost a pen lift without adding to the picture is skipped, and short closing segments are no longer lost.
• Guests can now choose how many copies to print right on the booth screen, and reprint earlier photos from a touch gallery.
• The Artist loader now ships with built-in artist clips, picks a different artist each time when set to Random, matches the cut to your screen’s orientation, and plays as the caricature wall starts drawing.
• The guest upload pages (QR upload) are now available in all 26 languages.
• New option on the pay-and-draw phone page to hide “Choose from gallery”.
• Node port names and default node titles in the editor are now translated, along with more operator screens that were still showing English.
• Looping video clips that stalled just short of their end now recover instead of freezing.
• The public printer QR code is now drawn dark-on-light on its own card, so phones scan it reliably.
• The empty-cell placeholder on the caricature mural now loads correctly, and the artist clips are included in the Raspberry Pi package.

Spanish throughout, and prints that keep their borders

• The whole app now speaks Spanish — every operator screen and every guest screen, from pre-flight and the node palette to the booth, the gallery and the assistant.
• On first run the booth follows your computer's language instead of always starting in English. Picking a language in Settings still overrides it for good.
• New Fit mode on the print node — "Fit whole image" keeps bordered and framed designs intact instead of cropping their edges away, with a margin control and a nudge for printers that feed slightly off centre.
• Overlay frames can now be scaled and positioned, so a frame that bled past the printable area can be pulled back inside the paper.
• New Base Image Scale and Background Colour on the overlay node — make the photo sit smaller inside the frame and choose what shows around it.
• Add your own logo to the live caricature drawing performance — pick its size and which corner it sits in.
• New waiting screen while a photo is uploading to the gallery, and on the Public Upload QR step — show a message, a still image or a looping video instead of leaving guests on a blank screen.
• Photos that failed to upload while the booth was offline are no longer lost — they are queued and sent as soon as the connection returns, and guests are no longer handed a QR code that scans to nothing.
• Fixed a blank white screen at the start of the drawing performance — the drawing now begins straight away, and when there is no line work to ink the time goes into the colouring instead.
• The finished caricature now stays on screen for the hold time you set, instead of cutting to a white mural view.
• Looping videos on Raspberry Pi booths no longer freeze on their last frame.
• Fixed the Apple Silicon Mac app shipping Intel-only helper tools, which silently broke caricature line work, video steps and remote tunnels on clean Macs.

Editor for iPad & the live print queue

• New Editor (Basic) — your whole booth flow as a numbered list of steps, built for editing on an iPad: large rows, large controls, tap a step to change it. The node canvas is untouched and one tap away as Editor (Pro).
• New live print & plot queue in booth view — see what is printing or plotting right now, on which machine, and what is next in line, with a thumbnail per job. Switch it on in Settings → Booth.
• New Print Quality setting on the print node — draft, normal or photo quality, read straight from your printer's own driver. Existing flows print exactly as before.
• New Fill Solid Regions option for plotting — solid areas such as filled eyes are hatched in instead of disappearing from the drawing.
• The assistant now shows example prompts above the chat box — tap one to send it.
• Plotter settings that only apply to outline mode are hidden while centerline mode is on, so every slider you see does something.
• Caricature presets now open with English booth screens by default; per-guest phone language is still available.
• Screen rotation now works on the Raspberry Pi desktop instead of failing with an error.
• In-app Update Now now works on Raspberry Pi installs, and no longer reports a false failure while the booth reboots.
• Fixed a hotspot leftover that could leave a booth "connected but with no internet" until it was rebooted.
• Dropbox connecting works again, and the booth now shows which Dropbox account it uploads to.

The living caricature mural

• New Living Caricature Mural — every guest caricature is drawn straight into its own cell of a giant wall that fills up over the course of your event.
• The attract screen shows the mural building live, with a scan-to-join code and clear instructions so guests know how to take part.
• Guests can add a handwritten message and signature from their phone, shown right next to their caricature on the wall.
• Messages and names are checked automatically before they reach the wall, so nothing unwanted ever goes public.
• Guestbook fields are translated into 25 languages.
• Print the finished mural as a branded poster, with a choice of grid layouts and A-series paper sizes.
• New operator Mural panel — reset the wall, clear a single cell, or swap in a replacement photo mid-event.
• More reliable face detection on phone uploads, plus a safety check so failed or unsuitable photos never reach the wall.
• Printer and paper-size selection in preflight are now instant, and the booth warns you when AI credits are running low.
• Fixed stretched prints on paper sizes other than 4x6.

Local gallery, instant sharing & plotter precision

• New local gallery mode — every photo from your event is saved on the booth and browsable on the spot.
• Guests can take their photos home instantly by scanning a QR code, straight from the gallery.
• Email sharing — send any photo to a guest by email right from the booth.
• Replot any photo from the local gallery in a couple of taps.
• More reliable plotter preflight checks before every job.
• Fixed a first-launch hang on machines connected to DSLR cameras.
• Firmware flashing now logs its full output to make troubleshooting easier.

Rock-solid USB plotting

• New SD-card plot mode for USB plotters — on by default for faster, steadier prints.
• Plotter setup now tolerates bad USB cables and recovers from macOS USB resets.
• Fixed WiFi scanning failing on Mac.

Plug-and-play plotter firmware

• Built-in one-tap firmware flashing — fresh plotters set themselves up automatically.
• Simpler pen mounting, with calibration buttons placed right beside the pen-height sliders.
• In-app confirmation dialogs replace browser pop-ups for a cleaner kiosk experience.

Sharper line-art & new print styles

• Crisper AI line-art prints with a new Line Detail control.
• New Toast Sticker, Mosaic Mural, and Sticker presets.
• Faster plots that better preserve your image margins.

Guests print straight from their phones

• Guests can scan a QR code to upload their own photos for printing.
• Multi-photo upload, custom QR colours, and friendlier inactive pages.
• Cloudflare tunnel is now bundled, so QR sharing works on fresh installs.

Robot arms & dye-sub printers

• DexArm robot-arm plotter integration.
• Automatic setup for dye-sublimation photo printers.
• Queued plots, a Stop button, and varied line weight for caricature prints.

Run a fully wireless booth

• Complete wireless customer flow — operate a booth with no cables.
• Captive-portal WiFi setup that also works over Ethernet.
• Cleaner editor toolbar and g-code preview images.

Redesigned plotter controls & safer homing

• Reworked plotter controls with clearer spacing, icons, and a Packing Position.
• Safer homing with a guided pre-home approach and limit-switch protection.
• Multi-click protection added to every plotter button.

Never lose work to an expired session

• Expired sessions reopen the login automatically — no more lost work mid-event.
• Replot any past design straight from the gallery.
• Friendly "out of credits" messages and a heads-up before credit-heavy AI jobs.

Hardened Mac reliability

• Plotting now survives macOS USB auto-suspend and mid-plot resets.
