P1S / AMS Setup Error

Since applying Studio 2.06.01.55 Beta, my printer can no longer print multiple colors from the AMS regardless of the filament (PLA, PETG, ABS). It prints the first color, unloads properly, and then feeds the second color and “jams”. Reporting that the extruder is blocked.

It truly is blocked. I have cleared it, cleaned it as proposed, and even changed out the hotend. Nothing has helped.

Each time I have to stop the print. Then with no print job running I have to head up the head and extrude some filament until it runs correctly again. After that, I can print any single color.

Help?

I have this P1S, I just bought an AMS hub and it requires an update from 00.00.00.42 to .43 fails at 50% every time. All AMS LEDs flash red. Buffer, cables, and unit are brand new. P1S only has 4-pin port so buffer cannot be bypassed. Issue persists after full power resets. And I was forced to remove and throw out my box from my dorm and now I probably can’t return it, does anybody or a god perhaps know what I can do?

Should I throw away the box? I was told not to throw it away, so I’ve been keeping it by the door, but it’s getting in the way.​​​​​​​​​​​​​​​
