Soft limit switch
First time on this Forum and it wont be my last, What I have been reading has been a lot of help, But now I am stuck.
I need help in setting up my soft limits This is my first CNC router That I have built it has a cutting table size of 850mm X 500mm it also has limit switch's on all axis.
The computer is an old windows XP that I got from a friend that hadn't been used since 2005.
When I start Mach 3 and get it to run a G code, all is well and it will home when asked. Then I will jog the X Y and Z to a new position that will be fine also, Now when I press the soft limit button and I jog back to the end of the table near the home position it will crash into the ends bending the limit switch. I do a manual check and find the limit switches are not working, I can move the axis away from the end and press the limit switch with my finger and none of the limit switches are working, when I switch off the soft limit and reset Mach 3 the limit switches are back working.
I have set the size on the Motor home / soft limit to 5mm smaller that the cutting area hoping that it would not bang into the stops, but I have already had to replace three switches as it hit them hard.
What am I doing wrong? I have attached a picture of the setting I have on the Motor home / soft limit screen.
Or could it be the computer does not have enough RAM to keep up with Mach 3 program.
Mike.
