When starting a print with the AMS everything is ok.
The AMS is loading the feeder sucessfully and the print is starting.
During the print the AMS is unwind the spool as the filament string runs shorter. Everything is fine so far.
Suddenly the AMS disconnects form the printer and is not longer recognized. That means the printer shows me “External spool” and AMS is not connected. Curiosly the AMS is still pushing the filemant to the buffer.
When the print is finished the printer wants me to unload the filament manually as it is an external spool.
The AMS is blinking red on all spools.
I have to abort the print.
Now i have to reboot the printer several times before the AMS is online again.
You can unplug and re-plug the cable that connects the AMS to the hub and from the hub to the printer to see if any of them aren’t making good contact. You could also factory reset the printer to see if that fixes it. If neither of those work there could be a short somewhere and if that’s the case you’ll need to open a ticket so they can look at the logs.
Same thing happening here I think! At first, I thought the filament was getting clogged and unable to retract, so I’ve been manually pulling out the filament at end of prints. But I just noticed my Studio–Device page doesn’t show the AMS during printing. And the error said the external spool needs to be extracted even though I’m using AMS. I thought it was just a shared error code for filament retraction issues regardless of which filament system you’re using, but now I’m connecting the dots. I’ve only had the AMS for a week. It wasn’t doing this for the first few days, just started yesterday. I haven’t updated to the latest P1S firmware if that makes a difference.
Hm, I made sure the connectors were solid earlier but just wiggled them all a little and it reconnected. May be a loose terminal connection causing problems. Will update if I figure anything else out. It’s weird that it was fine at start of prints and disconnected during prints – maybe just a very fickle connection somewhere causing disconnect with the printer vibrations…?
Ive just started getting this exact issue over the last few prints. AMS not visible and flashes red during print (but still works) then at the end it flashes red and the print is almost complete but needs to be cancelled.
Has anyone found a solution? I certainly do not want to place all the components in the AMS.
i am having a similar issue but mine works fine until the full print is finished and disconnects after that (my p1s runs 2 ams’ units and the only time it does this if i install the newest firmware)
i had my machine running on 1.0.8 no issues as soon as i updated it started happening again this is the 4th or 5th time i run into this issue.
as i have 2 other p1 series printers i switched all the cables and even went ahead and ordered 2 brand new cables 1 4 pin and one 6 pin to test and still the same issue with newest firmware i am going to revert it back to previous again and wait until they release the next update for that p1s
I am having this issue as well. I have a spare AMS for testing, which came with all new cables. I changed it out. The problem still exists. AMS disappears a short while after after the print starts. So its not the AMS or cables. Could it be the buffer? The AMS came with a buffer unit and I will change that out next. If that doesnt work, its on to taking the back panel off and checking the AMS board connector on the X1. If that doesnt work, then I have already ordered a new AMS board for the X1 and will replace that. Ugghhh. Seems like so many people have this problem.
UPDATE - I also tried replacing the AMS Buffer. Problem still occurred. I ended up having to replace the AMS board connector on the back of the X1. It was fairly easy to do and that has resolved the problem. No more AMS disconnects.
But mine only happened when I update the firmware.
I am currently using 01.08 firmware cause every time I have updated it to the 01.09 it will print fine for the first print and then it will disconnect and it will disconnect both my ams.
I purchased the 4 pins and the 6pins cables replaced them and still the same issue so I reverted back to 01.08
