I am at a loss, and maybe someone else can help me on this.
Fanuc 18T
It has happened where it has appeared that the Z limit switch area has gotten too many chips flung up there - most always when running alum.
I open the rear door and clear out any debris in the channel, and all seems fine after that.
Even when that would happen tho - it would go in Z+ in cycle, but not in JOG.
Well I am experiencing that again, and now I am actually down as I cannot get it to HOME out.
I checked both L/S's in Z. They both look clean and dry and check out fine with the meter. (continuity alarm anyhow)
If I click the O/T switch - the machine goes into E-stop right away. That works...
If I click the HOME switch, I can see it light up in the PLC. That works.
I can go into the ladder and the ladder sees the Z+ button on the HMI. That works.
I have had this machine for 24 years, and I cannot think of anything else that would be holding this thing up from JOGing in Z+.
Again - I have got the LA (lower axis - sub spindle linear) and the X to HOME, the Z just needs to return to the Z+ HOME L/S, but won't go.
And again - if this thing was HOMED, it would run parts fine as is.
Somehow I think the answer is in the ladder pics here.
The X axis works fine, but the X output is in the Z line on the next page, and seems to possibly be what is holding it up, but I don't understand how?
What am I missing?
EDIT:
Looking at those ladder pics this AM, I guess that I don't think that the answer is there anymore.
