Live View
Live View shows the machine while it prints: the bed plate, the arm at the real nozzle position, and the observed nozzle path drawn behind it. The component only reads from the machine and never sends commands.
It does not record the print to a file. Every job is logged by Duet Console, which records on its own whether or not this component is on the canvas.
Panel: 7 Print. Nickname: Live. Compute button: no (runs on every change).
Inputs
| Name | Type | Default | Description |
|---|---|---|---|
host |
Text | Host output from Duet Console or Duet Connect, connected before live preview | |
enable |
Boolean | true | Read the connected session and animate its live position when true (automatic output updates are a separate menu option) |
gcode |
Text (list) | Fallback G-code text or lines for the intended path, used only when the shared session has no job | |
bed |
Text | Print Bed definition text for the plate preview (unwired = no plate) |
Optional group: Kinematics overrides (L1/L2, reach, elbow)
Right-click the component to switch this group on. The inputs appear only while the group is enabled.
| Name | Type | Default | Description |
|---|---|---|---|
L1 |
Number | 549.06 | First SCARA link length in mm |
L2 |
Number | 457.23 | Second SCARA link length in mm |
baseHeight |
Number | 0 | Base Z height, mm |
reachMax |
Number | 0 | Maximum SCARA reach in mm (0 = L1 + L2) |
reachMin |
Number | 235 | Minimum SCARA reach in mm (0 = the absolute difference between L1 and L2) |
elbow |
Integer | 1 | Fallback SCARA arm mode for drawing: 0 = up, 1 = down, used only without a tracked session configuration |
Optional group: Robot definition (generic Duet machines)
Right-click the component to switch this group on. The inputs appear only while the group is enabled.
| Name | Type | Description |
|---|---|---|
robot |
Text | Robot Definition text for the live preview (unwired = Potterbot SCARA, Cartesian profiles show the nozzle without an arm) |
Outputs
| Name | Type | Description |
|---|---|---|
pos |
Point | Reported nozzle position in Rhino document units, mirrored for Potterbot and unchanged for Cartesian profiles |
J1 |
Number | First SCARA joint angle calculated from reported position, deg (unavailable for Cartesian profiles) |
J3 |
Number | SCARA elbow angle calculated from reported position, deg (unavailable for Cartesian profiles) |
J2 |
Number | SCARA Z carriage height calculated from reported position, mm (unavailable for Cartesian profiles) |
status |
Text | Raw machine status |
progress |
Number | Job progress, 0 to 1 |
info |
Text | Connection, intended-path and live-display diagnostics |
trail |
Geometry (tree) | Observed path in Rhino document units, one branch per continuous run as a polyline or a single point, with gaps preserved |
Compatibility with development files
A document saved with an earlier internal development build may still carry these sockets. Opening it reports them once and drops them.
| Removed | Replaced by |
|---|---|
bedWidth, bedDepth, bedCenter |
the bed input and Print Bed. Saved values migrate into a real Print Bed component |
extWidth, layerHeight |
the extrusion preview on G-code Generator and Robot Simulation |
logEnable, logEveryN, logFolder, logPrefix, logLayerHeight, logExport |
the Duet Console’s always-on job logging |
outputs layers, log, path, logInfo |
the Duet Console’s job logs and Recent prints |
Grasshopper drops wires to removed outputs without asking, and trail now sits at output
index 7, so an older document is asked to delete those four wires by hand.
