Hi folks .
Trying to get used to UCCNC
Am trying to get my head around Soft limits and having some difficulty.. Not really intuitive could we say?
So taking things one step at a time lets look at a single axis, for which of course we will choose X
So I have entered the settings for the home switches and they work, home and display resets to zero. so I am fine so far .
I select to use soft limits in general config
My thinking is that I want "soft limits" to define a work area in x positve which is bounded by the lower limit ( say 10) and an upper of say 350. I figured that the software would then stop any motion at 10 and prevent the machine hitting the home limit switch.
So I set lower limit to 10, upper to 350 but now when I home , the table goes all the way to the switch and DRO resets to 10 ??? says soft limit is reached (when actually the home switch has been reached) and a "write offset on homing" appears as 10. So what is the logic in this ??
I have read the manual , which isn't giving me clarity other than i need to set numbers for the soft limits.
I have sought for video tutorials but so far haven't found any which clearly explain what is going on here
I am not getting my head around it . I need to get this clear in my mind before I move on to Z axis and begin to regale you all with the issues setting the soft limits on there.
