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.

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.

Proof of concept encoder analysis. Still to not have a solid gear ratio but it's clear the encoder is very likely 11 PPR. Rotations take ~650 pulses, maybe 660 but it's hard to tell because the gearing makes stopping inconsistent.
