I have the Bambu 4 unit AMS Hub and I have four AMS Units they are wired 6 pin from printer to RHS AMS1 Input, LHS AMS1 goes to RHS AMS2 LHS AMS2 to RHS AMS3 LHS AMS3 to RHS AMS 4 and the LHS of AMS 4 Left open ( I dont believe there is anywhere to connect it to. )
All four PTFE tubes go into the AMS hub.
Any of the first 3 AMS units can be accessed by the X1C, the last unit can not, I swapped units 4 and 3 , 4 was now operational and 3 was not so I changed the cables in case of a cable fault - no change.
tldr ; Anything up to any 3 in any combination of my AMS units will work, adding the forth and attempting to access it - accesses AMS 3.
Any help?
Oh and while we are at it - Bambu didn’t ship the damned screws with the hub, I found mention that they are M3 x 28 - Nope - they aren’t can anyone tell me the size of them please.
Well I managed to get it working but it’s really Janky Printer->AMS1->AMS2->AMS4->AMS3 - Why I literally could not tell you. But I can access all four units but in order top to bottom they go A,B,D,C which makes zero sense… Can any one explain this for me?
When I added a second AMS, and later wanted to flip them, I had a similar surprise: No matter how I wired them , they always stayed in the same order.
I think that the logic wires actually connect them all in the parallel, so that wiring has nothing to do with the sequence.
Instead I think that each time you add an additional unit, the printer saves the serial number and puts the new AMS in the next free slot. And that stays the same, no matter how you disconnect and reconnect the units.
I think somewhere is an option to make the printer forget all units. Then you can connect them one by one so the printer rebuilds the sequence. But I’m not sure anymore.
