soft limits
« on: November 17, 2008, 04:15:00 PM »
Question re: soft limits and home. Why not have soft limits 1 inch from home and slow down 1/2 inch from home, with mechanical limit switches 2 inches from home (and the opposite of home)? That way you could go home without triggering any slow down, but a runaway would be slowed down and stopped before it could do any damage. Also, is there a Go Home button somewhere on one of the screens?
Thanks, Bob

The soft limits do have a slow down setting and a distance, can't remember were it is as I only set it once and my machine is in a different building.
There is a homing button next to the DRO's on the left, it's a long vertical bar with ref all in it, you need to have homing switches enabled etc for it to work, also the homing direction.
Or have I miss understood you :)

OK, I totally don't understand the soft limit setup. If I define my XY work space as a 22" x 44" area that has limit switches 2" outside of that, and the Y axis has a 7" height with 1" to the limit switches above and below that, and I want to have soft limits 1" outside my XY work area and 1/2" above and below my Y, with a slow down setting of 1/2", shouldn't my Soft Limits settings be:
X Soft Max: 45
X Soft Min: -1
X Slow Zone: .5
Y Soft Max: 23
Y Soft Min: -1
Y Slow Zone: .5
Z Soft Max: -7-1/2
Z Soft Min: +.5
Z Slow Zone: .5
When I do this, I can still jog right past all of the soft limits. And, what is Home Off.? And also the manual says, "the defined limits only apply when switched on using the Soft Limits toggle button -- see Limits and Miscellaneous control family for details." Where the heck is that??? Anybody?
Thanks again, Bob
