SETTING UP TOOLCHANGE RETRACT
I purchased the mmu2s upgrade for my original mk2.5s for multicolors but i cant get toolchange retracts setup right. I changed the length of bowden tube leading to the y splitter from the hotend and also the length to the mmu2s unit, and now the filament gets jammed in the splitter because the old tool doesnt pull back filament far enougfh for another filament to push thru the Y and into hotend, without jamming against the old tool filament in the Y.
also cooling moves take place in the wrong place now.
can someone tell me how to setup the distances for toolchange retracts and cooling correctly. where to enter new position of cooling moves and setup long toolchange retract so it pulls the old color out of the way so another color can load.
thanks in advance,

Can you post some pics? You say MMU2S, but there is no "y splitter" for it. That sounds more like a part for the original MMU.

LOL sorry. accidentally put the 2s on there . sorry no pics but I am talking about the original mmu that i purchased to add to my original single color printer .I bought it a more than a year ago and havent even used it yet.
I need to know how i use my longer ptfe lines and where to put the toolchange lengths in prusaslic3r so it retracts the filament all the way to the storage position.
The length from my hotend to the storage location is now 340mm when completely unloaded ,and now i want it to initially retract 50mm for cooling moves before storing the filament 290mm further retracted ...
so how do i split that up between retractions for toolchange in prusaslic3r 2 under printer>extruder # and also in settings>single extruder MM setup so that everything lines up and filament is stowed in the correct place after it is shaped and cooled?
