I set "move spindle up before tool change" to true in pncconf but it doesn't seem to have an effect. The tool change prompt pops up but the spindle doesn't retract.
checked the ini for TOOL_CHANGE_QUILL_UP = 1 in the emcio section
found instead, TOOLCHANGE_QUILL_UP = 1. (missing the first underscore)
Adding the underscore fixes the problem.
