In our current setup we use Sanyo Denki 103h7126-0740 Motors, which are linear until about 1000 to 2000 pulses/second. We are using 8 Microsteps, so the normal 200 steps per revolution (1.8 Degree step size) must be multiplied by 8, which gives 1600 steps per revolution. | In our current setup we use Sanyo Denki 103h7126-0740 Motors, which are linear until about 1000 to 2000 pulses/second.

Now we can calculate the maximum speed for a axis by taking the maximum pulses/second and divide it by the steps needed per mm (266,6 on our machine): | Now we can calculate the maximum speed for a axis by taking the maximum pulses/second and divide it by the steps needed per mm (266,6 on our machine): | ||

We need the factor 8 here because of the microstepping. | We need the factor 8 here because of the microstepping. | ||
