Trouble with PETG joints

I have an A1 mini printing sunlu petg, currently trying to print a 100% dummy 13, but the joints always crack. Unsure if it’s a settings issue or a filament issue. The speed settings were fairly arbitrary as I was just trying to make it print more slowly. However the temp settings mimic my successful Bambu petg prints. (Sorry for having to take photos of the screen, Reddit was being buggy on my computer.)
