{"product_id":"terradial","title":"terraDial","description":"\u003cp\u003eterraDial is the control panel your terraPen bench has been missing. A 240×240 round touchscreen with a knurled rotary knob, it talks straight to your plotter's controller over Wi-Fi — no laptop, no phone app, no cable run across the studio.\u003c\/p\u003e\n\u003cp\u003eTurn the knob to jog X, Y, and Z with selectable step sizes and set a zero per axis. Pick a job straight off the plotter's SD card and watch live progress on the dial, with elapsed time and an estimated time remaining alongside the percentage. Lift the pen, drop it, home the machine with a clear-the-bed confirmation gate first, or hit E-Stop — findable at a glance because it's the one control that's always red. If an alarm trips, the dial shows the machine's own error message, not just generic advice. If your rail is running terraPixel lighting, control brightness, film mode, and comet width from the same dial.\u003c\/p\u003e\n\u003cp\u003eSetup happens on the device itself: scan for your network, enter the password with the radial keyboard, and you're on. A five-LED status ring around the bezel reports machine state visibly across the room, and the display sleeps itself during long plots so it isn't glowing at you for hours.\u003c\/p\u003e\n\u003cp\u003ePower comes from a single USB-A cable: plug it into the plotter, a USB port or a phone charger. Firmware updates arrive over Wi-Fi, so that cable is all it ever needs. Runs happily off a USB battery pack too, for a plotter that isn't parked next to an outlet.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKnob-first control: jog axes, run jobs, adjust settings, all from one rotary dial with touch as a second input\u003c\/li\u003e\n\u003cli\u003eLive job progress with elapsed time and an estimated time remaining, plus an SD card job browser — no laptop required at the plotter\u003c\/li\u003e\n\u003cli\u003ePen up\/down, homing with a clear-the-bed confirmation, E-Stop, and alarm clear — the alarm screen shows the machine's actual error, not a generic message\u003c\/li\u003e\n\u003cli\u003eRail lighting control via terraPixel: brightness, film mode, comet width\u003c\/li\u003e\n\u003cli\u003eOn-device Wi-Fi setup with network scan and radial keyboard password entry\u003c\/li\u003e\n\u003cli\u003eFive-LED status ring, readable across the room\u003c\/li\u003e\n\u003cli\u003eSleep mode to protect the display during long plots\u003c\/li\u003e\n\u003cli\u003eUSB-A powered; runs from a USB battery pack for cable-free setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcessor:\u003c\/strong\u003e ESP32-S3R8, 16MB flash, 8MB PSRAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e 240×240 round IPS touchscreen, SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTouch:\u003c\/strong\u003e CST816D capacitive controller, I²C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e EC11-style rotary encoder with push switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatus LEDs:\u003c\/strong\u003e 5× WS2812 addressable RGB ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e USB-A cable (plotter, USB port, charger or battery pack)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirmware updates:\u003c\/strong\u003e over Wi-Fi, from the dial's own settings menu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectivity:\u003c\/strong\u003e Wi-Fi, talks to FluidNC over WebSocket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with:\u003c\/strong\u003e any plotter, laser, or CNC mill running FluidNC firmware over Wi-Fi — including terraPen, most FluidNC-based DIY builds, and machines like the UUNA TEK 3.0 series, which ship with FluidNC firmware and Wi-Fi as standard.
