Duet Console is the one window for controlling a printer with
a Duet board from Grasshopper. It handles connecting, homing, jogging,
capturing the bed origin and the nozzle height, checking and uploading a
job, starting, pausing and cancelling it, sending single commands,
driving to calibration points, and keeping the job logs. The connected
robot profile must advertise Duet control; a profile that does not is
refused with “use a Duet profile”.
Panel: 7 Print. Nickname: Console. Compute button: no (runs on every change).
Inputs
Name
Type
Default
Description
gcode
Text (list)
G-code job as text or a list of lines, overridden by a job loaded from Recent prints until cleared
host
Text
192.168.1.42
Duet hostname or IP address, optionally with :port, required before connecting in the console
password
Text
Duet password (empty = ‘reprap’), saved unencrypted in the .gh file and sent over HTTP
pollMs
Integer
1000
Status poll interval in ms, clamped to 250 to 2000, or 250 while the console is focused and the machine is active
robot
Text
Robot Definition text for the connected Duet machine (unwired = Potterbot SCARA, Cartesian profiles disable go-to)
points
Point (list)
Calibration points in Rhino document units for the SCARA go-to selector, used after connecting and homing
live
Boolean
false
Refresh changed visible outputs at most once per second when true (false = refresh on the next solve)
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
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)
zMax
Number
400
Maximum machine Z in mm, corresponding to the firmware M208 limit
xMin
Number
-300
Minimum machine X in mm, corresponding to the firmware M208 limit
xMax
Number
10000
Maximum machine X in mm, corresponding to the firmware M208 limit
yMin
Number
-10000
Minimum machine Y in mm, corresponding to the firmware M208 limit
yMax
Number
0
Maximum machine Y in mm, corresponding to the firmware M208 limit
checkEnvelope
Boolean
true
Check targets against the machine’s Cartesian axis limits when true
elbow
Integer
1
Fallback arm mode, 0 up or 1 down, for planning before a verified home exists. A verified home’s endstop mode takes precedence
Optional group: Jog feedrate
Right-click the component to switch this group on. The inputs appear only while the group is enabled.

Default
Description
feed
Number
20
Jog feedrate, mm/s (capped at 50)
Outputs
The outputs are grouped into six categories. A new component shows only the three pinned
ones, host, status and gcode; right-click and use Outputs shown to switch a
category on. Switching a category on or off moves the socket indices of the ones below it,
so wire by name. A category that carries a wire is never hidden, by hand or on load, and an
older document keeps every category that had a wire when it was saved.
Connection
Name
Type
Description
host
Text
Session host to wire into the other Print components. Shown by default
connected
Boolean
True while connected, even if machine identity checks prevent control
Job
Name
Type
Description
status
Text
Console status: the connection, then the pending action or last result. Shown by default
state
Text
Machine status
progress
Number
Job progress, 0 to 1
jobFile
Text
Printing file (empty when idle)
uploaded
Text
Remote path of the last verified upload (empty when none)
gcode
Text (list)
Running or prepared G-code lines, including Recent prints selections (empty for jobs started outside this session). Shown by default
Motion
Name
Type
Description
pos
Point
Reported nozzle position in Rhino document units, mirrored for Potterbot and unchanged for Cartesian profiles
homed
Boolean
True when all visible axes report homed
xHomed
Boolean
X axis homed
yHomed
Boolean
Y axis homed
zHomed
Boolean
Z axis homed
bedOrigin
Point
Captured plate origin in Rhino document units for Print Bed’s center input, without changing firmware offsets
zZero
Number
Legacy captured Z in Rhino document units from saved documents, with no new captures
Validation
Name

Overrides
Name
Type
Description
speedFactor
Number
Speed override, percent (-1 = not reported)
flowFactor
Number
Flow override, percent (-1 = not reported)
-1 is not 0: a machine that does not publish a factor and a factor genuinely set to
zero must not read the same.
