New MK4 Build - Use the MMU3 Nextruder parts first?
Heya, folks! This may be a quick answer I may already know, but I figure I'd confirm..
I bought the whole kit, MK4 and MMU3.. I'm putting together the MK4's Nextruder now, and there's the new idler lever set that came with the MMU3 kit.
I'd like to assemble the MK4 and get it working before dealing with the MMU, but should I just use the new parts anyway, or will there be issues since I'm not using the MMU yet?
Thanks!

My advice would be use the stock parts first, make sure everything is working, then swap in the MMU parts. I imagine the calibration when you first turn on the printer assumes you're using the stock Nextruder and I'm not sure if having the modified Nextruder would affect that.

I would build it stock and then make sure it works perfectly before adding the MMU3 to the mix.

Well, I decided to live dangerously and use the MMU3 Nextruder parts first!
Looking at them it wasn't much of a departure from the standard setup - there's now an O-Ring in around the planetary gear I guess to center things a bit better, and the idler lever now actuates the filament sensor instead of a ball and spring. It actually makes sense since the idler lever would never really wear out with the bearings and it's made in a much more durable material.
The only thing I had to do was in the initial setup phase where everything is tested. I simply just unclipped the idler to make it think there was no filament, and then in the menu settings you can tell it there's the MMU sensor config instead from there onwards, even if you're not using the MMU. I wonder if this may be an update for all MK4s down the road, or is it only necessary with the extra filament traffic from the MMU..
So in retrospect it wouldn't take much more effort to install the OEM parts and then update, but it seems there's no harm in it either. Everything has been working great so far sans-MMU (just need to build the buffer now)
