hi, same error her ..

ERROR: Injecting GCODE failed. Replaced 0 out of 1 needed.

thats a problem with the regular expression matching the line from the slicer. you need to make sure the expression is right for your slicer

(you have also the procedure to print in multicolor)

On Octoprint go to settings and then "GCODE Scripts" insert this code into the mentioned fields:

After print job is paused:

M117 Print Paused
G91 X # Set to relative positioning on the X axis
G1 X20 # Move my bed down 15mm (or the hotend up 20mm)
G90 X # Set to absolute positioning on the X axis

Before print job is resumed:

M117 Print Resumed
G91 X # Set to relative positioning on the X axis
G1 X-20 # Put the bed back
G90 X # Set to absolute positioning on the X axis

Hit save. Then also in settings go to "Plugin Manager" and click "Get more..." In the search box type "colors" and install the Multi Colors plugin. You will find the plugin by clicking on the 4 bars / arrow down next to "Timelapse" in your Octoprint menu.
For it to work with Cura 3.2.1 sliced gcode you must go to your multi color printing menu (which you just opened) hit "Advanced Options" and replace the regex (regular expression) with the following: ;LAYER:{layer}

Now you are good to go. Just use "GCode Viewer" in Octoprint to find the layers at which you want to change color. Then go back to Multi Colors and type them in separated by space. Like 125 127 to change color at layer 125 and then again at layer 127 :)

For Cura, use

;LAYER:{layer}

instead.

Try this as your regex statement.

.([LAYER])\w+.*([layer]).
