Upgrade path from MK3.5 to MK3.9s ?
I have a MK3.5 currently (and also a MK4). I do like the Nextruder on the MK4 as the nozzle swap is so much easier and efficient. The perfect first layer is also fantastic, then there is the huge weight reduction due to using a pancake motor, that lone will help with residence reduction as it doesn't have so much weight to stop and move in the other direction.
Due to these reasons, I wanted to know if there was a path to upgrade from the MK3.5 to the MK3.9, essentially the Nextruder (as the xBuddy board and LCD were done with the 3.5 upgrade). I didn't see this as an option when looking at the MK3s+ upgrades as it shoots straight to 3.5s or 3.9, then 4s but nothing between these.
Let me know if there is something available.
*NOTE to Prusa team - it might be a good thing to add to the upgrade options, then those folks like myself can upgrade a little at a time or as needed (its more cost effective for some folks like myself to do it in smaller hops vice all at once).
