Description

The LED resistor for the stepper driver enable line is too high a value for a clear indication. If there is insufficient current available then it will have to do but if it is just a incorrect value on the schematic and/or BOM it could be altered.

My rev.3 schematic and the build instructions BOM says 10k, same as the Vmot LED resistor. The V5 LED resistor is just 1K and the 3.3V Opto resistors are 330 Ohm. Perhaps something between 1k and 330 Ohm would be suitable.
