I fixed some things in the MaxStepper Firmware. You can see the release notes in the KCam folder if you install the latest version of KCam(.24). If Max works for you now, you won't see and big changes. Mostly I fixed the inverting options for the inputs and outputs of Max. If you are one who needed to add an inverter to a limit switch or an enable line, this upgrade will fix that. It also reverses the direction of the motors properly now without the need to rewire the motors.
