Z hop after extruder switch... and before?

[tech108 0]

I'm pulling my hair out trying to get z hop settings correct. It's so close to what I need but not quite.

 

I have an IDEX printer and I'm trying to get the extruders to Z hop into the print and then Z hop out of it, but I don't want any Z hop while it's retracting. The Z hop at extruder switch pulls the head up out of the print before it moves out of the way, which is correct, and then it lowers the Z axis and moves the active extruder across the print. The result is I get little specs all over the print from the ooze as it wipes itself across the outer shell. 

 

I've been able to get it to work by checking the "z hop when retracted" and "retract at layer change" which will pull it up before it enters the print, but then it's also doing a z hop every few seconds with every little retraction as it prints, leaving stringing everywhere. 

 

Is there a way to get it to "z hop at extruder switch" but not lower the z axis until it's over the portion it's going to start printing on?
