I noticed they aren't the strongest when they just keep going if I hit the hard end stop.

Looks like I have some fixing to do. In the meantime I've managed to get all the axes to jog and found the pins/port combination to get the spindle to run, but I have no control over it.
Keep getting the PWM bumped to minimum warning even when I enter big numbers.
Any clues on how I get control? The screen overrides won't work but I can start it from there or the F5 key.
