AMS Slot 2 Gear Stuck

[Yaad]

Hey guys,

Recently did a long print where slot 2 finished and then it auto-fininished the print with slot 4, since it was the same filament. That’s awesome… but… now slot 2 seems to be stuck. I can’t load anything into it. There seems to be a gear that prevents it from loading. Check this video that explains the problem better:

Typically, it is the driven roller which helps you unstick the feeder gear. Put a spool into that slot, and roll it forward and back until the roller unlocks. Please report back if this works for you?

Hi MiamiJerry,

I was super excited when I read this and immediately tried it out. But unfortunately didn’t work

You will need to disassemble the AMS, and then the pre feeder.

I have a spare pre feeder for AMS 2 Pro, Later today I will look and see if I can design a tool to unlock the pre feeder in place without disassembly.

Using a 1.4mm drill rod, I am able to move the swing gears, both left and right gears to the engaged and disengaged positions.

Verify that the driven roller is seated properly. This link shows a picture of a roller that has lifted up.

AMS Retraction problem

After contacting support and working them through emails, I have fixed my problem. The problem was that the front roller was just a bit unseated. I oiled and reseated it and seems to have fixed my problem. I took a picture showing the roller unseated. [roller] Thanks all for your help on this!

Hey MiamiJerry
I have exactly that issue: the gear jumps up and locks the roller, and it can be unlocked using your technique.
Do you have a solution to prevent this from happening? It occurs quite often for me.

I describe the two solutions that I am testing in this thread,

Stuck, jammed front roller, solutions?

Thanks for the heads up on the notices. I’ll keep a closer eye on the responses. Great to be here. I’m really enjoying my new hobby.

I have not published them yet. So far they are both working. Please provide as much detail as you can on what you are expriencing? Are you using cardboard spools?

I had a similar issue when a few desiccant beads escaped from their container and got stuck between the gears. I had to disassemble the unit to remove them.

However, looking at your video, it seems that the gear has somehow jumped past its stop. There are two stops on the side of the transparent cover. Try removing the cover and repositioning the gear correctly, if you haven’t already solved the issue.
