#IDEX retraction and flowrate?

I've been trying to tune my machine for a while now, it's now printing pretty good on each toolhead black petg-cf and regular petg in pink, both park benchys look pretty good to me. 0.16mm, 4 Walls, 4 bottom/top layer 5% infill -> 35min

I don't understand why the idex print looks so bad though! Z offset as well as XY offset look good to me and seem to work great,
but it seems that retracion and flowrate are terrible?

No z-hop, no prime tower, no oozing prevention in Slicer. This is my special config, the rest is stock:

variable_toolchange_extrusion: 1.6
variable_toolchange_retraction: 1.6
variable_toolchange_standby_temp: -1
variable_toolchange_first_purge: 15
variable_toolchange_purge: 10
variable_toolchange_prepurging_timer: 200```

Any help much appreciated! 🙏🙏🙏

To print without prime tower, you need to decrease the temperatures. When the toolheads are parked, the filament temperature inside the nozzle converges to the target temperature, making the filament more fluid (it oozes when the toolhead resumes printing). When printing, this does not happen because the filament that is being extruded at any given time is not actually at the target temperature.

The best way is to just to print the prime tower

(its a bit wet so still not perfect, but close...)
