Hi, in order to prevent oozing from the unused extruder in dual extruding I would like to put some lines in the preSwitchExtruder.gcode section. The best way is to lower the temperature of the unused extruder to a value below the melting point. My questions: 1. How can i detect the number of the used and unused extruder to set the appropriate temperature values? Is there a variable like {used_extruder} or {unused_extruder}? I would be very interested in a list of variables, wich can be used in start, end and switching codes. I did not find it with google 2. is it possible to put conditional statements, for example "IF" , in the pre(post)SwitchExtruder.gcode? If it is possible, the code could like this: IF (T{used_extruder} = 0) M104 T0 S240 IF (T{unused_extruder} = 0) M104 T1 S200 or without a conditional statement M104 T{used_extruder} S240 M104 T{unused_extruder} S200 Regards
