Tool change G Code Garbled

Recommended Posts

I'm trying to implement a section of G-code during a tool change, shown below:

EXTRUDER START G-CODE
; Start Extruder 1
M211 S0 ; Turn off soft stops
G1 X-9.5 F6000 ; Go to X=-9.5 at 100 mm/sec
G92 E0 ; Reset extrusion distance on new tool
G1 E50 F90 ; Extrude 50 mm of filament at 1.5 mm/s on new tool
M211 S1
G92 E0 ; Set current extruder position to 0mm
G0 F10000 ; Increase feed rate before next travel.

 

 

EXTRUDER END G-CODE
; End Extruder 1
G92 E0 ; Reset extrusion distance
G1 E-5 F5000; Retract 5 mm
G91 ; Switch from absolute positioning to relative positioning
G1 Z1 F1000 ; Lift nozzle by 1 mm in relative positioning mode
G90 ; Return to absolute positioning
G92 E0 ; Reset extrusion distance on old tool

 

I do this for each of my two extruders under the machine settings for my printer.

 

The issue is that when I slice a file, save the G Code, and then view the G Code in Notepad++, one/both of the sections of custom G Code are unreadable. They show up as non-characters, and the printer doesn't execute them. If I copy/paste the text in my snippet above, it never makes it to my G Code. Any idea?

For example, the extruder start g-code above ends up as ��� (or however your text editor shows unreadable characters).

 

It isn't constant. The same start g-code will work perfectly for another file, or it'll only be garbled for the first 10,000 lines of the g-code file, etc. and appear normally after that.

    • "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.
