Well still haven’t had time to set up the SV04 so as all good 3d printer people do they go out and buy another printer, purchased the SV01 to fill a gap ,so will have two to setup now and not just the one. Will I ever learn 
I guess the more the merrier. I also have two printers, the Ender 3 Pro, and now the Sovol SV04. The alignment step does take more time then the leveling, especially when it is a new process to learn. Mabey it should be pointed out that the sv04 leveling process is the same as a single head printer, and once done, can be used as a single hothead printer until one feels comfortable or has time to perform the 2nd hothead setup/alignment procedures. Further, I think that dual and mirror print modes would be usable once the 2nd head Z offset is set, the simplest of the 2nd head setup steps. So folks can ease into using the 2nd hothead printing.
I’m one to think that more printer I have the better I feel 
It allows me to start working on one printer (to improve something or at least I think it will ) and when something goes wrong and I need to modify a part, I can just use another printer to do it!
Well I think I can sell this to the wife , that is very good logic . (I think so anyway) 
New SV01 turned up today ,so have got the weekend covered for this week.
BTW, In my last post in this tread, I said that the 2nd extruder z adjustment was easy… Ate my words today. Had a heck of time getting it set. Every time I tighten the set screws, the head raises some about. Took me many tries, probably 6-8 to get it right.
