I’m not sure there is a “best way” to place them, as long as :
- you keep them as close as possible to the X1 (reduce PTFE distance = reduce time needed for load/unload of filaments, which may be relevant for long multi-color prints)
- you keep PTFE tubes aligned without too strong angles
Keep in mind that with the AMS HUB (needed for >= 2 AMS) you’ll have an extra ~2 meter compatible PTFE tube that you can use to replace the (very short) PTFE tubes that are available by default at the output of each AMS (allowing other ways to place the AMS). Replacing that outside AMS tube is easy and described in STEP 1 here : Replacing AMS filament hub | Bambu Lab Wiki
Also keep in mind that the AMS hub is NOT reversible : all PTFE tubes are going to come from the “right side” of the printer (when facing the printer), so it’s easier / better to have AMS located on top / right side / bottom of the printer, but not on its left (it’s of course still possible but with extra length of tube being wasted just for the loop, hence extra distance in the end)
Of course you are probably also still want to be able to open the AMS in order to change spools…
On my side i have some IKEA BROR shelves :
- The X1C is on one shelf at mid-height
- My two AMS are on the upper shelf, one next to the other one
- One AMS just “on top of the printer” (with a bit longer tube than default one)
- One a little bit on the right (still with default PTFE tube)
