7981250d5a Changed from dev mode to working mode. Lamp turns on after 24 frames. Will make it configurable.

39650094bd Code is in test mode for getting approximations of the motor speed with no load, under single strand of film load and with 2 films. Should be possible to create a control loop to maintain a roughly-accurate speed.

7c8be86fb8 Motor speed is now calculated (flawed). Tests can be run on various PWM speeds, resolutions and with and without loads to determine the ability for the printer run at maximum speeds.

db1f8c4100 Make some sacrifices in the DriveMotor class to make it non-generalizable. Working towards porting timing functions from encoder proof of concept sketch.

1aca2dd5c0 Motor behavior is stable. Discarded one of the L298N boards: now we can run the drive motor off one channel and both takeup motors off another. DO NOT USE LESS THAN 2A. Using 1.3A the motor controller board draws too much and shuts it down. Removed the rerences to Picture/Stock and am just using takeup. All progress at Worm.

6dad4a5314 Resizes reels. Was 99mm diameter and works in larger patersons but not the standard 2 reel model. Resized to 94mm to match the standard reels. Removed a single rotation of the spiral. Should fix the spiral implementations to accept a desired length, not just an integer of rotations.
