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.

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.

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.

Implement pwm ramp up with ledcWrite(), not analogWrite(). Use directional pins to start in particular direction and stop in both. Ramp behavior should move to loop so that it is not blocking loop behavior.

Frame has been resized and new panels have been drafted. Still not perfectly parametric and the const variables are getting out of hand. Needs a refactor at the top and then throughout panel modules first, removing magic numbers. Rounded panel corners at frame corners (one per panel). Printing this draft for possible revision if needed.

Caught the error that was making me think I broke my ESP32 dev boards. The ledcWrite() duty cycle was not being set on the pwmChannel. This is intended for LEDS but I don't know if it matters that it's being used for a variable speed DC motor.
