Move the pot to change duty cycle. EC doesn’t simulate PWM with motors very well due to speed constraints, but this should work. Haven’t had a chance to build one yet.

You can adjust the simulator speed by clicking on the little clock and adjusting the simulator speed there

True, but the calculations aren’t quite fast enough and everything acts kinda funny.

You can increase the sim speed by adding a frequency source (doesn’t need to be connected to the circuit). For example a 1kHz source will cap the effective sim speed at 333μs/s and increasing it further (up to a limit of 3ms/s) will make it run faster but with the same precision as 333μs/s. You can then adjust the frequency of the source to adjust the precision of the sim.

Oh wow, great tip thank you!
