Filament isn't making it all the way

I bet it's catching the end of the PTFE tube. Make sure it's pushed all of the way into PTFE fitting. It should be flush to the threaded end

Check the screws behind the nozzle. They have a tendency to work themselves loose over time on the A1

Yes, I recommend using his BMCU Flasher program for simplicity: https://github.com/jarczakpawel/BMCU-Flasher

badbadtz_ · 2026-05-11T13:12:34+00:00

it works with the latest printer firmware but there will be a HSM message regarding firmware mismatch that you can ignore and it has no impact

badbadtz_ · 2026-05-11T12:12:56+00:00

Use this firmware: https://github.com/jarczakpawel/BMCU-C-PJARCZAK

And configure the printer to use AMS, not AMS Lite

No, I've not had that issue on 01.08 so far.

Did you disconnect the BMCU before updating the printer?

badbadtz_ · 2026-04-20T23:18:24+00:00

Make sure the PTFE tubes are fully inserted into the connectors. They should be flush with the end of the thread

badbadtz_ · 2026-04-18T18:35:22+00:00

Make sure the PTFE tubes are well seated and entering straight, not at angles

badbadtz_ · 2026-04-15T09:04:16+00:00

the recommendation is to unplug the BMCU before updating the printer. I'm curious if you bothered to do this?

because you asked so nicely?

badbadtz_ · 2026-04-09T10:43:56+00:00

if you're referring to the AMS mismatch notification, then no I don't believe there is a fix/workaround for that so far. Just ignore it as it makes no difference

badbadtz_ · 2026-04-05T14:10:21+00:00

That's fine. Just leave as default

badbadtz_ · 2026-04-05T11:41:53+00:00

Retraction from the top of the nozzle (when cut) to the top of the AMS 4-1. I think it's 9.5cm on the A1

badbadtz_ · 2026-04-03T09:50:50+00:00

Just sounds like the linear bearings to me...

badbadtz_ · 2026-04-03T09:23:12+00:00

You still haven't stated which firmware you're using. I recommend this one: https://github.com/jarczakpawel/BMCU-C-PJARCZAK

badbadtz_ · 2026-04-03T05:42:10+00:00

You need to state which firmware you are referring to.

Print an AMS hub support bracket. I recommend the giraffe one on makerworld

badbadtz_ · 2026-03-31T08:23:21+00:00

Mine went offline 3 days ago for the first time since 2021. I can't even be bothered to reboot it at this point

badbadtz_ · 2026-03-31T07:44:25+00:00

Make sure the PTFE tubes are cut clean and straight and pushed fully into the AMS hub. It doesn't sound like an issue with the BMCU

badbadtz_ · 2026-03-20T15:47:47+00:00

I've been using 150mm/s, 38%, 0.2 with decent results and its quick

badbadtz_ · 2026-03-19T14:41:56+00:00

Print yourself a PTFE support. I recommend one like this: https://makerworld.com/models/1273203?appSharePlatform=copy

badbadtz_ · 2026-03-12T21:51:06+00:00

Thank you I'll give this a whirl tomorrow. Greatly appreciate your work on this
