These are called pings and are required for the machine to know how much filament it has used. you are not at risk of fire because filament does not catch fire until 388 degrees celcius . If you looked up the MSDS you would know this. Flammability: Autoignition temperature: 388°C
So i ran into this issue as i needed to print brackets for work, to make your screw holes stronger set your walls to 6 or even 8 and that will give you a great area for the screws to bite onto.
Why does the pause need to happen when running in Accessory mode? I mean the Palette isn’t even talking to the printer to make sure it’s got the right pings to pong back?
