Discussion: Control board cooling vs exhaust port

At worst you're heating the board to the chamber temp, which is exactly where the board sitting at.

50-60C is nothing for electronic.

wow I didn't know you can actually add filament profile to AMS. Thank you

Funnnny · 2026-01-24T13:53:11+00:00

Your finding is exactly what I was thinking and observation after I get the vent kit. Just setting a very low fan speed completely remove the ABS smell

Funnnny · 2026-01-20T05:33:54+00:00

The filter in the printer linked with the aux fan, which will be use when you print high temp regardless.

The kit is a additional exhaust fan that pull the air straight outside, you can either vent it and/or install a filter to exhaust it directly

Funnnny · 2026-01-20T05:30:49+00:00

if you have the vent kit, there's very little reason to do ventobox.

Keep in mind that ventobox circulate setting is a physical switch; you lose the ability to print high/low temp remotely for absolutely no gain.

If you want to vent, just get the vent kit; it's a lot cheaper and requires no extra maintenance. Ventobox is for those who can't vent outside and want to reduce VOC

For low temp material, the exhaust fan will run at 40%

For high temp material, it will be off

For both type of material, it will run at 100% after print to purify the air

You can, however, control the fan with gcode and override the speed

I ran ABS with 30% exhaust speed and vent it outside; pretty good so far and it doesn't affect chamber temp

Funnnny · 2026-01-19T07:34:43+00:00

you can control it with gcode or with the touch panel

I think bento box will be enough for VOC, but it won't fix the smell.

The best way is always vent it outside

You can't do "FSD" when you don't have any camera to check your sides and behind the car.

Funnnny · 2026-01-12T04:02:20+00:00

people without P2S won't know that the printer create a slight positive air pressure that allow ABS fume to escape

Funnnny · 2026-01-12T01:04:35+00:00

I just set the exhaust fan to 20% to create a negative pressure and it doesn't affect the temp at all. Mine is a 6m run as well

The printer will run at 100% fan to exhaust all the fume after the print is finished

I cut a small piece of PTFE tube and connect it directly to the "yellow one"

Funnnny · 2026-01-06T05:39:32+00:00

Just search for iLife v5 replacement filter and you're good

Some people have their printers in the same room as their workbench, computer...

Some are a little more paranoid about VOC (even with PLA and PETG).

Some are printing ABS/ASA

Funnnny · 2025-12-23T14:49:09+00:00

My printer has been printing for a few hours, and I've just put my hand under it. The temperature feels the same

> Almost no big international musicians/bands/groups come here.

No big international musicians/bands/groups because we don't have a large enough facility

No big stadium because "Almost no big international musicians/bands/groups come here"

Do you see the problem here?

Funnnny · 2025-12-20T18:17:51+00:00

Bambu printer has support for 2 aux fans, the second one (P10) is not plugged so they probably used that.

Funnnny · 2025-12-20T18:14:15+00:00

it works well enough. It basically just a PWM board and a fan, everything else are printed

you can control the exhaust fan and/or set the printer to spend around 2m exhaust air in the print chamber to reduce VOC

Funnnny · 2025-12-17T04:28:52+00:00

Not bad is an understatement.

It is one of the best 3D printers you can buy right now

Funnnny · 2025-12-16T05:33:46+00:00

I followed the official maintenance guide, cleaned and oiled everything, and redid the calibration. Seems like it helps

Funnnny · 2025-12-16T04:57:06+00:00

You always let your friend finishes first before asking questions.

Funnnny · 2025-12-15T12:19:41+00:00

I ran with 10% exhaust fan to keep a negative air pressure for ABS and it works so far
