AMS v1 Replaced nearly ALL Circuit Boards

Ongoing issue:

AMS v1 Blinking Red Lights

Have only used AMS v1 for a few hours since being bought new in June 2025.

I recently upgraded the AMS (v1) Main Board, the AMS Power Board, the AMS Buffer, and the 4-Pin and 6-pin cables were changed.

I then verified connectivity with a multi-meter, to make sure each pin in each 4 & 6 pin cable had perfect conductivity from one connector to the next connector.

Both the new 4-pin and 6-pin cables were working correctly.

Before connecting the AMS v1 to the P1S printer, I then started measuring all the resistance values as I had done before.

And was somewhat disappointed that the same Open Circuits persisted despite installing a new AMS Main Board, AMS Power Board, AMS Buffer, and new 4-Pin and 6-pin cables.

The only AMS Port or interface that provided correct resistance values was the Printer 4-port connector on the back of the printer.

I also measured the 24 VDC values exiting the 4-pin cable from the printer.

Which measured 24 volts.

I then measured the 24 volts arriving at the rear AMS 6-pin connector.
It was correct.

I then measured the 24 volts arriving in the 2-pin cable going to the AMS Main Board.
It was correct.

The blinking Red LEDs continues.

The P1S is using firmware v1.09

I have no idea what firmware is on the AMS Main Board, since the P1S cannot communicate with it.

At this point in time I have no idea what else to try.

Looking for guidance on what steps to try next.

Hey I’m dealing with a similar issue. Was wondering if you ever resolved this? Really bit that much info on people troubleshooting this issue that I can find.
