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.

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......

Ok, got it, good to know - and I do not know that much about Linuxcnc and lastly, Pnnconf / MESA stuff. All new.
But, all limits working now. I just need to check the probe setup - think that I can do after the limit switch and HalShow stuff initiation.
But, my ESTOP is still beyond me. Saw threads where JT and I believe a few others talked about inserting lines that linked the ESTOP pin to other pins or feedback - tries several but beyond me once again.
ESTOP - loaded all pins and all ESTOP, Abort, Charge pump references into HalShow, enabled [it's a NC switch] my external ESTOP button and nothing in Halshow changed color. Yes, my external button is wired into the mx3660, and yes it shuts down the motors on push.
I tried to move the ESTOP to different pins that were open and then Halshow - no change. The probe pins work in Halshow so I know that is at least on the right pin and gives feedback - I can figure that out.
So any suggestions on ESTOP? Else I will live with it the way it is. Still have a lot of changes to do with travel and positioning in the ini for axes but that's easy stuff, just takes me a little longer one step at a time.
