I'm having the same issue. The suggested work around of using an existing dual extruder printer and modifying it are a one shot deal for me. If I choose another machine that supports dual extruders, I can set the machine parameters once, but then they revert each and every time I import a new model (e.g. the build plate volume, extruder offsets, etc. all get lost). This also appears to occur if I simply close and reopen the program. This is really a pain if I must do it each and every time
. Is there a solution to creating an "other" dual extruder profile that will retain the machine settings? Can we create a copy of the "base" profile and edit it (I could not find where these files are stored)?
