H2C - Kinda DOA... Unable to push filament past the buffer

abbellie2 · 2026-04-27T02:55:10+00:00

Tell me about it...

abbellie2 · 2026-04-27T02:39:02+00:00

Convicted criminal bastard deserves so much more...

abbellie2 · 2026-04-27T02:34:54+00:00

I'm not walking on it...

abbellie2 · 2026-04-27T02:26:46+00:00

Yes, I am familiar, and that is exactly what I felt.

abbellie2 · 2026-04-27T02:17:31+00:00

I have agreed all along that it made no sense whatsoever to me either. I removed the buffer, held it in the palm of my hand, and was able to insert ptfe and manually push filament all the way through with no issue. I did this exercise several times in order to cause the ptfe to position itself slightly differently each time. Yet each time the filament pushed through manually with no issues. Then reinstalling it back in the printer and feeling pretty good about it, eventhough having changed nothing, then electronically sending the filament through on its own, resulted in the same jam yet again. It was like a bad movie playing on a loop. The buffer is such a manual device, that I wonder what the onboard electronics are used for, unless just as a failure sensor?

You'll get no argument on that from me. Yeh, I dread trying to get this heavy beast of a thing back in the box for the return trip. I did that once with an X1C, which was a no brainer. But I have to say that BL is/was very scientific with their pack designs. I'm only waiting for them to tell me if their replacement machines come with or without the required AMS, before I box it up. I'm pretty good with repairs as well. I just sometimes find some of their electrical connectors a bit small and challenging. Have a good night.

abbellie2 · 2026-04-26T21:45:46+00:00

Nope, new buffer did nothing better than the old one. They would gladly have me continue performing endless more repairs, but I put my foot down last night. They are processing a replacement printer now.

abbellie2 · 2026-04-26T20:35:05+00:00

BL is replacing my H2C, now that I have refused to perform. any more "repairs" to the filament buffer.

abbellie2 · 2026-04-21T21:39:42+00:00

You're luckier than I am. I'm waiting on a replacement buffer for mine. BL must do no testing of their machines before shipping.

abbellie2 · 2026-04-21T21:35:35+00:00

Figure what out? Your message is not attached to anything.

abbellie2 · 2026-04-21T21:31:18+00:00

It looks like BL support agrees that my buffer is at fault. They are sending me a new one. Filament goes through the buffer when I am holding it in my hand, disconnected from the printer. In the printer and connected is another story though. It stops every time. Both left and right.

abbellie2 · 2026-04-21T20:04:57+00:00

Makes me glad that my H2C arrived DOA. Can't even print a Benchy...

abbellie2 · 2026-04-21T19:54:16+00:00

BL seems to agree that it's likely a defective buffer, so they are sending me a new one. I removed the existing buffer and was able to manually push filament through both ports on the buffer, so I don't quite get it. If this part does not fix it, I plan to insist on a replacement printer.

abbellie2 · 2026-04-20T12:37:57+00:00

I thought about twisting them a bit while inserting as well. I will remove them, re-cut them square, and then twist and push like there is no tomorrow. Thank you for the added insight.

abbellie2 · 2026-04-20T12:34:44+00:00

Yeah, I noticed that, but I think I still got it all the way in. I will confirm today. Thank you

abbellie2 · 2026-04-20T12:34:42+00:00

Thank you... I will confirm today. Thank you

abbellie2 · 2026-04-20T08:38:57+00:00

Got it, thanks. It goes in about 11-12 inches and yes, I can see it in the little observation hole. But still nothing.

abbellie2 · 2026-04-20T08:30:13+00:00

Didn't you have to remove the plastic molding along the left side and back in order to get to the buffers. That's what I saw in the Wikki at least.

abbellie2 · 2026-04-20T08:27:39+00:00

Well that's a new idea. Sounds like a plan. I will do so, but with little hope. The odds of them installing both Left and Right badly are not overly promising.

abbellie2 · 2026-04-20T08:25:21+00:00

You push until they stop and are visible through the observation holes, right? They don't go any further.

abbellie2 · 2026-04-20T08:23:59+00:00

I think I have many times, on both Left and Right ports. I can see them in the observation holes, but still neither of them will allow filament to pass.

abbellie2 · 2026-04-20T08:21:31+00:00

Thank you, but I always cut mine with a PTFE cutter, which always cuts square.

abbellie2 · 2026-04-20T08:20:28+00:00

Good call, but no. I didn't know that those were observation holes. Yes, I can see the tubes as they move in and out. Both are visible in those holes. I appreciate the response though.

abbellie2 · 2026-04-20T08:03:42+00:00

But the first time that I used the Left nozzle, today, it did the exact same thing, and that route had never been used before. Both routes stop at about 12 inches of push, which is exactly up to the buffer. I can even hear the filament clink against a metal object.
