General Mach Discussion / Re: mach3 lathe homing and help

Hi Hood,
You were correct i was pushing the wrong button, DOHH i knew you would be correct. all works perfect now.
all axes jog the correct way and match up with the dro. and machine homes to top right corner perfect.
I even managed to get the vfd to work with variable speed inputs from mach3, just need to wire in the index sensor now and i think nearly there.
Thanks again hood top man.

On a mechanical note does anyone know much about the boxford 240? mine seems to have a lot of backlash, any way of solving this apart from new ball screws.

Thanks
John

Thanks hood
I will try your settings tomorrow and let you know
I did try the x and z home buttons as well but didn't work but I will check again tomorrow
Is your screen available might work better
Thanks again

General Mach Discussion / mach3 lathe homing and help

« on: January 06, 2013, 03:11:41 PM »

Hi All,
Hope you can help, I have a boxford 240 cnc lathe(slant bed) i have just converted to mach3 everything went well, but i have a few questions.
When i try to home the axis nothing happens when I press home all. The limit switches all work fine show up on the diagnostic screen, cant work it out.
Also some basics, jogging i press right arrow key z axis moves right dro moves + and opposite for left i think this is correct.
The x i think is wrong i push up arrow x axis moves up but dro moves - i am confused my lathe shows z+ right and x+ up.
is this something to do with the toolpost being on the rear?

Thanks for any help
