On my K3, there is a red dot next to each camera speed on the dial. In order to run at a marked speed (24fps, etc) you need to align the red dot next to the number with the red dot on the outside of the speed ring. If the dots are not aligned, the motor is running somewhere between the marked speeds. I don't know how you would verify the actual speed outside of analysing the projected film.
Thanks Mike. That's what I'm doing. I guess I was expecting the dial to be more precise and have a tighter feel in turning. It seems fairly loose. I'll line up the two big red dots at 24, test some film, and hope for the best. Perhaps I'll tape the dial down at 24 so it doesn't move accidentally. By the way, how's your registration look in the final print? I know these cams are a far cry from a pin registered Arri but just wondering. Any other advice would be much appreciated. Thanks again.

I have checked K3s using the Tobin Speed checker and it's very tough to get one to maintain 24 fps spot on for any length of time. Of course doing MOS work this really doesn't matter, close is usually good enough.
Yes the loop guides will scratch the film so follow these steps.
1) Once the film has been advanced over the gear, through the loop guide, and is being held by the claw behind the pressure plate. Pull up the silver disc on the gear, and back the film off 1-2 perfs. Yes this will make the loop a bit smaller which is exactly what you want to do to make sure the film does not touch the loop guides. The film will run through fine pulled back 1-2 perfs.
2) Repeat this process for the bottom loop as well.
3) Wind lots of film onto the take up spool and make sure it's tight. I've seen students try to go cheap on film and use only one or two lengths around the take up spool, only to discover that the film came off the take up reel.
4) Run the camera at 8 fps with the cover off to inspect the film movement and make sure it's not touching either loop guide.
5) Now run the camera at 24 fps with the cover off and inspect.
6) Put the cover on and lens cap on, run at 24fps for a good 4-5 seconds to clear off all of the exposed film created during loading.
7) Now the K3 is ready for it's first real shot.
And there you have it, now get out there and execute order 66.
