new prob ,,, setting soft limits

jog moves properly  x -- moves left to home sw                  X+ move toward right side         
                            z -- moves head up  toward home sw     
                            y -- moves gantry toward home sw       Y+ move toward top of table

+Y
|

I had to reload wxp  and have forgotten my config set up and having to retrain myself...
I have set my home sw and limit switches.......
Home and limit are same switch ..
.but when jogging I hit a limit  and stop ,,, I must manually move off the limit

I was thinking I could set some software switch so that when limit was hit machine would reverse off until off of limit switch and then EM stop
or did I dream this up......

where / what box do I check

General Mach Discussion / Re: Explanation of "Charge Pump" needed

 I start mach3 pgm ..It starts the 12.5khz charge pump signal,,I detect the 12.5khz signal ind turn on a solidstate relay
which turns on the raw 36volt powersupply....then I take 5 volts from control card to hold the solid state relay......

I was wanted to develop enough voltage from the charge pump to energize the SSR without using an external 3.6volt battery
but I don't believe I will be able to achive this......

Now to power it off I will use a mcode to control another output pin....

I figured this would be an easy way to pwr machine on/off while testing......

Now since it appears I will need a 3.6volt battery,, I may just use some seldom use m-codes to apply and remove power...
or may just add a toggle button on screen to control it

I just toying with this idea,, I don't like walking 20 feet back and forth power cycling machine...

The main concern is no signal on pin 1

I am planning to use the charge pump to enable me to apply power to my cnc machine....hopping to not use battery ,,,,but not looking good...
ie start up mach3 ..which starts the charge pump .. which applys power to the machine....

While looking into doing this I found that I cannot use PIN 1 for charge pump ie pin 1 acts dead ??

I can use Pins 14,16,17 with no problem.... cable continuity on pin 1 is ok....

I will use an Mcode to power machine off....and yes I could use Mcode to power on

Not sure im my parallel port has a problem or not...

Is there anybody using pin 1 for charge pump...

I playing with the latest demo code....
