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

    Hello,

    Im struggling with this issue also.

    what would be nice is, a preSwitchExtruder1to2.gcode

    and preSwitchExtruder2to1.gcode

    and corresponding post switch files.

    I have a handful of things I would do differently when switching from 1 to 2 versus when switching from 2 to 1. anyone had any experience with this or know of a plugin that would allow you to easily perform different code when switching between either extruder?

    thanks
