#V1.1.0 -
|
|
# additions:
|
|
#Object number - To select individual models or all when using "one at a time" print sequence
|
|
#V1.2.0
|
|
# fixed layer heights Cura starts at 1 while G-code starts at 0
|
|
# removed notes

# Fixed mm bug when not in multiples of layer height
|
|
# Uses -
|
|
# M163 - Set Mix Factor
|
|
# M164 - Save Mix - saves to T2 as a unique mix
