General Mach Discussion / Re: Mach3 Parallel Port Home Switch

This is somewhat resolved.  The reason it was going passed the home switch is, I had the z and x axis home switches wired backwards on the controller so I was seeing the diagnostic light come on, however it was attached to the wrong axis so the x was actually wired to the z axis home switch pin.

Still struggling with home and limits and table sizes but I'm addressing that in another thread. 

I thank you all for your time.  Your insight is very helpful for this newbie.

I checked the boxes you suggested and the machine started homing the wrong way on the x and y axis so i checked the reverse box to get them to home towards my limits switches.  I attached the updated picture of my configuration.

Still I get the soft limits kicking in towards where i have my home switches.

Ok.

I'm not sure that explains the soft limit issue I'm experiencing.  Alhough I could be mistaken.

Thanks to both of you. 

"The most common location for the X- and Y-axis is probably at the most negative position of travel."

IF I am not mistaken thats where my table is in the original picture, which means, im somewhat getting it.

I guess the problem I am having is purely with soft limits.

This is my configuration in he pictures and the video shows what happens.

General Mach Discussion / Homing Position

« on: October 07, 2015, 07:53:21 PM »

I installed my homing switches based off of a couple mini mill examples on the internet.

Is the the correct position for "home?"

I am having trouble with the concept.  When I ref all home, it goes to this position in my example picture.  the thing I get confused about is when i jog away from its home position on the x or y, its a negative number. 

because of this confusion its hard for me to figure out my soft limits.

i have watched the mach3 tutorial on home switches, twice so far....im still just a bit confused.

If anyone could help explain this to me or point me in the right direction id appreciate it!

I pretty much have it setup out of the box mach3 with the gecko g540 xml config loaded.

z does attempt to home, and proceeds to go right past the switch only stopping when i hit the e-stop.

I'm going to attempt to resintall the software this evening to see if i had messed anything up along the way.

I've had a look at that as well as watching the Mach 3 tutorial videos on the main site.

I have been using these diagrams which show the home switch wiring seems to be correct.  Mach3 does properly see when the switch has been triggered.  It just fails to stop the motors.  Has me super puzzled.

General Mach Discussion / Mach3 Parallel Port Home Switch

« on: October 01, 2015, 05:42:00 PM »

I have mach3 setup with a gecko g540.  I have home switches on three of my axis.

I can hit the switch and watch the light blink on while on the diagnostic screen but it doesnt stop.  It just hits the mechanical limit once it blows past the switch. 

I've done some searching and spent about a week trying to switch things around but always get the same result so I broke down and made a post.

Can anyone lend a hand?  Your time is appreciated.
