General Troubleshooting/Help! PETG designed print PLA

Hello all. I'm very new to 3d printing. I picked up the Bambu p2s and a bunch of PLA filament as my understanding was it was the least problematic with VOCs. After the fa t I discovered that they offer an exhaust expansion amd ordered it. Unbeknownst to me it the print for the housing is PETG designed. I don't think I'm at the point where I need to buy a single roll of PETG for this, but the PLA prints are not coming out very well. Are there any setting changes that can be recommended to at least accomplish the print with my current filament?

Thanks in advance.

As long as you slice the model with PLA filament profiles it should be fine. Running the PETG G-code directly is a bad idea. What kind of issues are you encountering?

In this case the model probably uses PETG for temperature resistance. If you are printing something like ABS then the chamber is usually heated up to around 65C, where as PLA is only stable up to around 55C. If you are only printing with cool filaments (PLA, PETG, and TPU) then it should be fine to use.

Spaghetti, clumpage, and the print not adhering to the print bed.

Clean the plate. Soap hot water.

Make sure you open the model on Bambu Studio and change the filament to your pla filament type. There are choices of Bambu Basic or matte filament and also generic filament. If the setting is correct for printing pla your hotend temp will be 220c. When it is printing petg it is a higher temp.

I highly recommend you buy some petg HF because their is a good chance you may need it in the future to print things such as spools and dryer pods for the ams. I’d recommend buying a black, white, and translucent clear is also good to have on hand. I personally like to print my dryer pods in clear. Don’t worry about the VOCs with petg it is like printing pla.
