# Slic3r postprocessing script for RRF 2.0 (Duet)
|
||
|
|
#
|
||
|
|
# Configure it by putting the path to the .cmd file
|
||
|
|
# under "Print Settings" --> "Output options" --> "Post-processing scripts"
|
||
|
|
#
|
||
|
|
# What it does:
|
||
|
|
#
|
||
|
|
# * Insert a "T0" activation line if one doesn't exist before temperature setting commands
|
||
|
|
#
|
||
|
|
# * Rewrite all M104/M140/M109/M190 temperature commands into "G10" temperature commands
|
||
|
|
# so that they do not override Duet's standby temperatures.
|
||
|
|
# If you edit the print_end.g to disable the "option 1: turn off tool heaters" behavior
|
||
|
|
# and instead use "option 2: disable tools and set standby",
|
||
|
|
# then manually set a standby temperature before starting the print,
|
||
|
|
# when the print is finished it will hold your standby temps. (e.g. 170C hotend, 45C bed)
