Temperature in gcode
Hi,
First sorry for my English.
I begin to use my MultiMatrial kit and try to make a part of ABS supported by PLA.
However my question is the same with ABS + Verbatim BVOH or other.
In the Gcode generates by Slic3r I see this at the start (... to replace many lines for the sake of sanity ) :

; CP PRIMING END
;------------------
We see T0 and T3 for the change to the Extruder 0 and 3 the issue I have concern the temperature.
At the start we can see that :
M104 S260 ; set extruder temp
M140 S105 ; set bed temp
M190 S105 ; wait for bed temp
M109 S260 ; wait for extruder temp
if i undestand correctly the begin with 260°C in extruder and 105°C on bed.
When we select extruder T0 the temperature is correct (260/105).
But when we select the T3 extruder I can't see any M104 and/or M140 command then... my PLA gonna burn...
Can anybody point me what I don't understand ?
You can reproduce this gcode file simply in slic3r :
Thank you.
Re: Temperature in gcode
Alright, it seems that an bug of Slic3r prusa edition 1.37.1, you can update to 1.37.2 for this.
The Link : https://github.com/prusa3d/Slic3r/releases/tag/version_1.37.2
Re: Temperature in gcode
I think you will have problems when the temperatures are so different.
The MMU will only work properly with materials which have similar temperatures (maximum difference is about 15 degrees).
