resuming g-code

Recommended Posts

Hi, I have a large print that I want to pause because I don't want to leave my printer running unattended.

It stopped at layer 100. Now I would like to resume it at this layer the next time. I was thinking of just deleting the first 100 layers from the g-code and running the rest, is this possible?

The first commands at layer 100 look like this:

;LAYER:100

;TYPE:WALL-OUTER

G1 X73.206 Y124.307 Z20.2 F9000.0

G1 X20.861 Y23.532

G1 X20.069 Y20.68

will this instruct the printer to start at Z position 20.2, without "homing" first?

Also, should I change anything to the g-code start section?

I

;TYPE:CUSTOM

;Sliced file.stl at: Fri 20 Jul 2012 16:05:02

;Basic settings: Layer height: 0.2 Walls: 0.8 Fill: 20

;Print time: 41:22

;Filament used: 81.13m 691.87g

;Filament cost: Unknown

G21 ;metric values

G90 ;absolute positioning

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

G28 Z0 ;move Z to min endstops

G92 X0 Y0 Z0 E0 ;reset software position to front/left/z=0.0

G1 Z15.0 F180

G92 E0 ;zero the extruded length

G1 F200 E3

G92 E0 ;zero the extruded length again

;G1 X100 Y100 F9000

G1 F9000

thanks!

Richard

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
