Homing help
« on: December 13, 2011, 10:58:08 AM »
Hi Newbie here
I bought the Zentools 7x7 cnc and have Mach 3
I'm having trouble setting up the home switches
I have 2 switches in series for each axis so they are both home and limit switches
when I hit ref all  z axis homes perfect but the next one   y  will hit the switch and keep going
I've read for hours on this site and elsewhere but can't figure it out
any help would really be great

Sounds like you may have the switch set up wrong in Mach, if you attach your xml file I can see if there is a problem with your config.

Thanks for your help
Guess I'm a total newb, it took me awhile just to figure out where the .xml file was
I just got as far as getting the motors to move at that is it

If you go to the Diagnostics page in Mach and then press a switch on the X axis, do the M1 Limit/Home LEDs light or do the M2 ones light?

X should be M1
Y M2
Z M3

so if yours are as you say you need to swap the pin assignments round in Mach.

Awesome thanks
rewired it and it homes correctly now
When I hit a limit switch how do I reset so I can move it off the switch?
I'm having to turn them by hand to get them off the switch

Thanks Hood
