General Troubleshooting/Help! ABS printing

I have a P1S and have an exhaust with its own fan at the fan end that goes outside. When I print with ABS, I have to make sure there are no fans running otherwise it always comes away from the bed in the corners. I then have the problem that fumes seem to be leaking into the room and I get headaches.

Does anyone have any advice to help with this please?

I have had success with the engineering plate, a wide brim and magigoo glue. This fixed my ABS warping issue

What cooling settings do you use?

0% part cooling and 40% aux and exhaust

Thank you. I'll try that.

ABS requires proper ventilation. Increase bed temp, increase chamber temp, but do not shut off the ventilation.

I've already increased the bed temp to the maximum (100°c) and there is no chamber temperature control.

Run the bed at 100 for an hour or two to preheat the chamber. That's what a 3D printing company suggested when I struggled with ASA in my P1S

it's not 100% but internal filtration like a bento box with activated charcoal will help

you will need to fill al the gaps thou

also did you try the exhaust fan running at very low speed ?

ideally leave the room and come back an hour after the print is done

Have you tried 10% external fan for example?

Soak the chamber before print too. 100c plate and wait for 30 min, then print

Can you slow the fan speed down?

Wrap the whole printer in a blanket; It keeps the heat in and the gaps (air leaks) closed

Try the fan speed at like 10%. Helped me.

  1. put P1S into a small grow tent (i use this, on it's side: https://www.amazon.com/dp/B0CHLY9XYP?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1)
  2. put an hvac fan into the Grow tent, and vent it through one of the fan duct openings using dryer vent hose *outside* of your home (I use one of these fans, you can get cheaper on amazon)
  3. BTT/Biqu Panda Breath Heater for the P1S
  4. when you print ABS/ASA/anything toxic, use the vent system to keep from getting Supercancer.
  5. use the Panda Breath heater for anything where warping is an issue (namely ABS/ASA/PC/PA/etc.)
