Why cant i upgrade a 3.5 to a 3.9 or 4

As prusa says it has 3.5, 3.9, 4 upgrade kits available for the MK3s+ why cant the do a kit for the 3.5.

Surly all you have to do is get a 3.9 or Mk4 Upgrade kit and remove the mk3.5 parts, so end up with a 3.5 upgrade kit and a 3.5 to 3.9 or 4 upgrade kit.

Contacted customer support and its a firm no, cant be done. 

they even suggested i could send my 3.5 kit back and buy a 3.9. Not a lot of help as its fitted and running.

Needed a machine that would run with MMU3 hence the 3.5, didn't think it would be a problem to update at a later stage.

Very disappointed with prusa. Easy fix except jobs worth attitude

The MMU3 works with the MK3S+?

Yes it does it also works great with the mk 3.5, 3.9 and mk4. However the point i am making was the first first printer with a new buddy board and mmu3 was the MK 3.5. The mk 3.9 and mk 4 came along later. having built a mk 4 from a kit and converted a mk 3s+ to a MK3.5 I didn't expect it to be a dead end. Prusa has always been known for its upgrades to the latest printer. However it seems that the 3.5 is a dead end. The stupid part is the kit to upgrade it to a ML3.9 or a MK 4 is already there if I buy a buy a mk3s+ upgrade kit and dont use all the bits needed to upgrade to a mk 3.5. All i have asked them to do is sell me the difference between the two. I would not have thought this was difficult and doesn't leave them anything they cant sell.

Do they offer any support when you buy a new 3.9 set?

you hit the the same point, the same tragedy that leaves many MK3.5-users very unhappy.
