Funny, the homing was INVERTED in Stepconf, but now is not in Pnnconf. Also the latest Pnnconf instructions do not match the Pnnconf I see on my machine. ????? documentation must be lagging I guess, realize everybody is busy and this is a free program......
Parallel port requires pulling inputs down to trigger,
Mesa can have inputs set for pull down or pull up, in hal
Mesa can use all pins as inputs or as outputs, in any combination, and they are much, much faster than parallel port, so it is impossible to have all possible combinations in a wizard.
