Maybe you need to clean and purge the nozzle before starting the print. You could always edit your starting script to do that automatically too

Do you have a scrip to purge the extruder before restart ? i think the extruder is purge corectly but is purge over the parts before restart is it possible to purge at the same place at the start first layer ???? outside the heated bed Platform ? thanks for reply .

Just look at your starting script. All the commands are commented pretty well. I think it already purges the right extruder. So just copy/paste that section and add a T1 before it so that it now purges the left nozzle.
