I am looking at build the A4T toolhead and it was pointed out that there is a v2 being developed. I can't find anything on the updates v2 brings. So I was wondering should I build v1 since it is released, should I build v2 and follow for any updates? How far along is v2? Is there any idea of when it will be released? Thank for all your help so far!

Bonus question. The configurator does not call out if it is v1 or v2. I assume v1 but I wanted to know if anyone know if that is correct?

I am planning to use my V0.2 as my main printer someday and I would need to print some models using 0.2 nozzle and some using 0.4 nozzle. I also can't really decide between Anthead toolhead and Dragonburner.

So, the idea is to have both with different nozzle sizes and change them manually when I need to, using the Stealthchanger mount (possibly CNC one). Sounds more fun than having one toolhead and unscrewing a nozzle every time, so the questions are:

1. Has anybody tried it?
   
2. Are there any downsides except potentially losing some build volume?
   
3. I assume I will need a way to calibrate toolheads, like sexbolt?

To be clear, I am not planning to put a full Stealthchanger system with docks and stuff on V0, just using the mount system to be able to quickly swap toolheads manually. The inactive toolhead will just be sitting on a shelf when not used, not on the dock.

Another way to solve this would be a double hotend toolhead like H2D has, or the INDX system, or the A4T-C hotend-changer, but those seem to be too advanced/pricey/not finished for me right now, so I would like to explore the Stealthchanger mount idea first
