Why MK3 asking for a color change?

I just did my first 2 color print and it went very well. I then started a single color job, and the printer paused and prompted for a color change when I didn't program one. It paused at the same layer as the previous print. Any idea how I can keep this from happening again?

My process was: I sliced the first job, then went to the colorprint web page and programmed the change and saved the gcode. I then uploaded the gcode to my Raspberry Pi 3b, and began the print job. Color change went flawlessly. After it was done, I sliced and uploaded a single color job to the RPi 3, and started the print from the Pi. I don't understand how gcode in one print can "infect" another print? Might there be some remnant in the RPi 3, or in the printer from the previous job?

Thanks for the help!
Chris

Re: Why MK3 asking for a color change?

is your filament sensor on? I would check that, and did your print have 1 files in it. maybe something with the mmu setting got on somehow

I have a Prusa,therefore I research.

Don't have a MMU. I just used the Prusa color change gcode generator on their website to set a color change in the first file. Each print was just one file. Weird. Second print is still running. I'll do a power off cycle on both the RPi and the printer and see if that clears it. I'm just wondering how this could happen so I can avoid it in the future.

the Laser filament sensor is unable to provide good results on certain filaments, particularly shiny ones, translucent ones and I believe green filament in particular
you might have more success if you turn the filament sensor off while Prusa investigate!

as long as you aren't playing around with m600. then hopefully just turning off the filament sensor should work.
