I have a atom 2.5 EX and I'm trying to use the second extruder for pva on a print.. its a delta printer with 2 extruders that go into one nozzle.. the problem im having is on the tool change. I got it to retract tool 0 to 100mm up the in the PTFE tubing putting it out of the way for tool 1 to start extruding by pushing the pva down the y tube.. but instead it just starts with it in its resting place, so i don't get any pva to come out. and then when its finished with that layer it retracts back up 100mm to where i told it to and then tool 0 starts to go but it starts form the 100mm position. how do i get it to reload the nozzle after the tool changes? I really love simplify 3d and don't want to try and reconfigure some other slicer to do prints like this... so if anyone can help me out that would be awesome!!!!
