Thanks Dahuss! I am going to comment on that line in the firmware. The firmware is lacking in comments on what parameters are representative of what. So for that line
{200, 200, 4535.44, 200} should be {X, Y, Z, ?}

So with a Nema 17 with a 1.8 degree step angle I am getting 80 steps per unit for X and Y.

I am using the formula:

steps/mm = (motor steps per rev)∗(driver microstep) / (belt pitch)∗(pulley number of teeth)
80 = (200)*(16) / (2)*(20)

Am I calculating this incorrectly? Because with a 16 tooth pulley that 200 should be 100 based off of the formula above.
