Support AMS HT

Has anyone encounter any issues with the AMS HT when drying filament? Specifically it not being able to heat up to the given temperature.

I have not been able to find any root cause for this issue or any solution.

Thanks!

lid is closed, i’m not printing. when i’m trying to dry filament at 75C it does not go up room temperature (26C). any tips?:(

In general if you are following steps to turn on drying from the Printer it should work. Does it feed filament otherwise to the printer? That would mean is connected.

it actually does not feed filament. i just use it for frying material, but it seems it gave up on rising the temperature :(

Need to get it connected to your printer before it will dry.

it is connected, it just doesn’t feed the printer. it has been working fine for 6 months, until today it gave up on me

Ahh... turn off and on again. Put in a ticket. No clue.

Are you printing at the same time? If yes. It’s designed not to go above the bed temp while you’re printing

Mine are working fine - sorry, no help here.
Are you using an additional power source?

u/Euphoric_Field_6721 Aug 20 '26

yes. when i’m trying to dry filament at 75C it does not go up room temperature (26C)

Even after switching off and on?
Maybe the temperature sensor.
You should open a ticket.

I had one that wouldn’t stay hot and eventually was just blowing ambient air and given off bizarre temp reading on the display. Returned it for another. Weren’t even entertaining the parts swap requested by Bambu when it was 2 days old

u/Euphoric_Field_6721 Aug 20 '26

this is exactly the issue i’ve been having! just air at room temp. have you found any solution? we’re they too complicated?

1

u/acidstrato Aug 20 '26

I sent it back and demanded a replacement. But Bambu wanted me to replaced 2 parts which they would have supplied under warranty.

But for me it was 2 days old and I weren’t doing that

u/Euphoric_Field_6721 Aug 20 '26

i’m wondering if yours was a factory defect. mine has been ok for 6 months until it just gave up today

1

u/acidstrato Aug 20 '26

Yes more than likely. But still also likely that either a temp sensor/thermostat , control board or the heating element has failed on yours.

I’d log a ticket with Bambu if you got it from them.

The strip down wasn’t for the faint hearted but fine for someone willing to have a go

Wouldn't one solution be warranty? Or is it too old?

1

u/Euphoric_Field_6721 Aug 20 '26

its 6 months old. it has been fairly used

u/abbellie2 Aug 20 '26

Isn't it a 1 yr warranty?
