The first thing I did was that the high-flow nozzle went into the box and is not allowed in the printer. And certainly not in conjunction with the MMU. The few minutes of time saved are not worth worrying about the HF nozzle. But that is a matter for each user.

As I would be using this upgrade with the MMU is the advice still to retain the original nozzle and not use the new high-flow one included with the upgrade? Thanks Guys

The increased overhang angle alone would be worth the upgrade in my opinion. Its a great increase in design freedom without having to rely on supports.

I would say yes. It is a good upgrade.

That is a personal choice... My MK4 is almost two years old and functions flawless, I see no need to fix something that isn't broke.

Same went with my MK3, bought the MK3s+ upgrade kit and only installed it before I sold the MK3 after I got my MK4.

I’ve had the upgrade kit for over a year but haven’t installed it. I use the MMU3 and it’s been working flawlessly. At the time I was concerned about losing that functionality.

What, if anything, would I gain by installing the upgrade now?

If upgrading is advantageous, is there anything I should be aware of?
