It's right.

1 / 23000 = 0.0000434783 sec
0.0000434783 / 0.0000005 -1 = 86.9565217391 = 86
2000000 / 86 = 23255
23255 / 500 = 46.511 = 46 // this is adjust factor

As above, my understanding is correct´╝č
Not entirely correct.

Wheel diameter 100 mm.
Microstepping - 16
Angle step - 1.8 degrees
One turn of the wheel = Pi * D = 314.15652 mm or 16 * 360 / 1.8 = 3200 microsteps.
500 * 46 = 23000 - the maximum frequency of the selected authors microsteps.
23000/3200 = 7.1875 - the maximum number of revolutions of the wheel.
314.15652 * 7.1875 = 2258 mm / s or 8.1288 km / h - top speed.
Hi guy,
why in this line, we dont use "speed" to calculate actual_robot_speed instead of speed_M1, speed_M2? The unit of speed is step/s, isn't it?
PHP Code:
actual_robot_speed = (speed_M1 speed_M2) / 2
and what 's actual_robot_speed 's unit?
