I have a custom tool changing printer with 3 extruders. to prime, I normally Bring up the tool, extruder 15mm, then tool change to the next tool and repeat. The problem comes when I'm not using all 3 tools. I was wondering if there is a to use if/then statements to only prime nozzles that are being used. is it possible to do some thing like.. If [insert tool temp here] > 100C then Prime gcode here Repeat for other tools this way, it won't waist time tool changing to the unused extruders that aren't even being used.
