G-code Restart

G-code Restart rebuilds a G-code file so that a print can continue after a failure. You tell the component where the print stopped, as a height, as the percentage shown on the Duet, or as the last position, and the component removes everything that was already printed, adds a safe approach to the restart point, and keeps the rest of the job. The component has a compute button.

Panel: 3 G-code. Nickname: Restart. Compute button: yes (runs only when the button is clicked).

Inputs

Name	Type	Default	Description
gcode	Text (list)		G-code of the failed print as one string or a list of lines
gcodePath	Text		Original G-code file path, overriding gcode and giving exact file positions for percent mode
z	Number	10	Restart at the first extruding move at or above this machine Z in mm, used if percent and point are unset
percent	Number	50	Restart file progress from 0 to 100 percent (multiply a Print component’s 0 to 1 progress by 100)
point	Point		Failure point in Rhino document units, overriding percent and z to resume after the nearest printed point
primeE	Number	0	Ram prime before resuming, mm of E. Refills the nozzle after an air bubble (0 = none)
travelSpeed	Number	60	Feedrate of the safe approach travels, mm/s
hopSpeed	Number	0	Feedrate of the final descent onto the part, mm/s (0 = travel speed)
retractSpeed	Number	2	Ram speed while priming, mm/s of ram travel
clearance	Number	10	Clearance above everything printed so far for the approach, mm
savePath	Text		Optional local file or folder to save on Compute, overwriting the target (folder uses restart.gcode)
robot	Text		Optional Robot Definition - the coordinate frame the job’s G-code was emitted in, exactly as the G-code Generator reads it. Unwired keeps the Potterbot SCARA frame (y = -x mirror) for the ‘point’ input and the resume / printed / remaining outputs; a generic Cartesian definition uses the machine’s own coordinates

Outputs

Name	Type	Description
gcode	Text (list)	Restart G-code lines
resume	Point	Restart point in Rhino document units
printed	Curve (list)	Skipped path in Rhino document units, to compare with the part already on the bed
remaining	Curve (list)	Path to print after restarting, in Rhino document units
info	Text	Restart selection, source accuracy and save status
