Motor Controller PWM PIN drive strength differences

I'm using the MCPWM (Motor Controller PWM) peripheral to drive the "step" pin on a stepper motor driver. The driver (Leadshine DM320C) has optoisolator inputs, so the ESP32 pin is basically connect to an LED via a resistor. The high pin of the LED is connected to 3.3V and the low pin is connected to...
