What are the overall dimensions of the GreenLean Machine?

The overall dimensions of the GreenLean Machine are approximately 86 inches Tall by 116 inches wide.

I have not received my order even though USPS says they delivered it to my home. Its nowhere to be found. The tracing number is 9405511699000140422765, please help me.

In the tracking for that package, it says it was "Delivered, Garage or Other Location at Address". The package was probably too large to insert it in the mail box. If it was delivered on your porch or garage as stated in the tracking, then a person may have walked away with it. Call your local USPS office and inform then that your package was not where it stated on the tracking.

.08" Pitch Timing Belt 1/4" wide (per inch) says that it is urethane, but the timing belt in the picture is black, which is usually neoprene. Is this belt urethane or neoprene?

The belt is definitely urethane. You are correct that natural urethane has a yellow to beige appearance; however, urethane can can be tinted to exhibit many colors.

.200" (XL) Pitch, 50 Teeth, 1/4" Wide Single Sided

If you are trying to determine the steps per inch (or mm) for that particular timing drive pulley, here is the formula: Steps per inch = steps / inch Steps = (motor steps x microstepping amount) The microstepping is how many steps to standard step from the motor. For 1/16 microstepping, there will be 16 steps for one standard step. Typically, stepping motors naturally ave 200 steps per revolution. Let use the 16 as an example: Steps = (200 x 16) = 3200 steps for one revolution Inches = how many inches for one complete revolution In the case of a drive pulley with 50 teeth and .2 inches from tooth to tooth, the pitch circumference is simply .2 inches x 50 teeth = 10 inches. Back to the formula: Steps / inch = (3200 steps) / (10 inches) = 320 steps/inch If you want more steps per inch (better resolution for your application), simply increase the microstepping amount, or reduce the pulley pitch circumference (smaller pulley diameter). Let's consider a smaller pulley, say 20 teeth with the same XL specifications: Steps / inch = (200 x 16) / (.2 inches x 20) = 3200 / 4 = 800 steps/inch Let's consider a larger microstepping: Steps / inch = (200 x 32) / (.2 inches x 50) = 6400 / 10 = 640 steps/inch

Does this belt with added length (example 96 inches) come as one looped belt, or does it come as a straight, continuous linear belt ?

This timing belt is sold as one continuous length, not looped.
