Printing the gear bearing...filament sensor weirdness?

Hey gang. Just finished building my MK3, and I'm really enjoying it so far.

I'm fooling around with the files on the SD card. I'm printing the gear bearing, and the printer beeps every once in a while and prompts me to change filament. It's not obvious to me that the g-code was designed with multicolor in mind, so I'm suspecting that the filament sensor is tripping and thinking there's no filament.

I'm using the Prusa silver PLA that came with the kit.

Am I on the right track? Could the optical sensor be mis-detecting the filament and prompting me to add more?

The tree frog printed fine.

I've given up and disabled the filament sensor. It doesn't seem to like my black PETG (esun cheap stuff, but works fine). It was generally ok on my Prusa supplied grey, but it would still trigger randomly once a day or so.

The value I get out of it being on is quite low (unless I'm running really low on filament, not common). The hassle of leaving it on is quite high (random print pauses that I may not detect for hours). It stays off for now.

I'm not sure if either of you ever discovered a fix other than disabling the filament sensor, but I seem to be having the problem now. Last night it woke me up twice beeping requiring me to load filament. I'm going to try disabling the sensor and hope that works so I can sleep tonight.
