I'm using this tool change script with sucess, and I even use a M109 to wait for cold down temperatures to. But I have a problem that I don't know how to resolve: at the very first layer the print starts without waiting for temperature to cold down in one of the extruders..oozing happens..anyone knows how to do this?..since when print starts there is neither old or new tool, I think the code as to be diferent..
I tried to set first layer temperature to cold down temperature in one of the extruders, but when layer 2 starts, layer temperature settings in S3D temperature settings tab overwrites the temperature in tool change sript code, so, that won't work. And only work if in the first layer only one extruder is printing. So, that isn't a solution.
