Dual printing with no purge bucket, no prime tower and no ooze shield

Originally!

It's an extraordinary design, congratulations on getting it to work! So you don't need to do any purge at all? I'm guessing you retract a little, otherwise your filament starts to brown in the nozzle while it waits, so I'm surprised you don't have to purge something just in order to get an even pressure flow on the restart?

Very nice!

Very nice! How much are you cooling the inactive hotend?
-
With 160C standby you don't need to purge anything. And browning will actually be an issue only if you standby too long such as second toolhead only start printing halfway up the print. In that case lower the standby temp to 95C
I also have a metal shim that will block the tip of the nozzle when parked. So this has been good enough to maintain the pressure.
The inactive hotend will always be above 45c in both scenario so the fan blowing the heatsink is always on for the duration of print
Thanks
