how to 'fix' a half finished print..

Recommended Posts

so 5.30 through my 6hr print the z stage hits a piece of scrap plastic I carelessly left at the bottom and jams...

I've seen a couple of people try to rescue prints, usually their print froze, so they knew where they were. but this kept printing several layers (which are of course all a mess)

I can count the number of erroneous layers - so I need to beg for a crash course in g-code now. is there some way I can ask the printer where it currently is in z?

I can then subtract n layers, find the relevant G1 ... Z in the gcode and snip everything before that point right?

are there any parts in the start gcode that I need to keep? I don't really want it to try and home the x,y,z obviously! and I think I need to reset the extruder so it doesn't try to extrude a stupid amount of filament - I forget the g-code for this :( but I think I need to keep the first 2 lines (M92.. and M109.. ) right?

thanks to anyone who helps!

my start g-code looks like -

;TYPE:CUSTOM

M92 E1075.04754031

M109 S210.0

G21 ;metric values

G90 ;absolute positioning

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 F400

G92 E0 ;zero the extruded length

G1 F75 E5

G1 E3.5

G92 E0 ;zero the extruded length again

G1 X100.0 Y100.0 F3500

G1 Z0.0 F400

G90 ;set positioning to absolute

G21 ;set units to millimeters

M113 S1.0

M108 S25.0

;LAYER:0

M106 S255

;TYPE:SKIRT

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
