Z travel exceeded and other mysteries

Post by ScotY »

So I’ve been trying to familiarize myself with tool offsets, work coordinates and Intercon on the lathe. I have several tools set up so far. Using Intercon, all I am trying to do is face off a piece of stock. I’ll post a couple of pics of my Intercon settings. For some reason, when I run it it says Z travel exceeded. The graph looks fine, I can MDI Z0 and it will move to zero and I can physically verify it’s not going to exceed the travel of the machine. I had it working just fine a few minutes earlier, I’ve looked at it over and over and I just don’t get it. I’m sure it’s a newbie mistake so if someone can steer me straight, it would be much appreciated.

Earlier when it was working, after it faced off the stock, it would move to my G28 position but the DRO readings for G54 didn’t make any sense. I also didn’t understand why that was happening. Anyone have an idea why? I didn’t note the DRO reading but the distancr from part zero didn’t make sense. I’ll have to see if I can make it happen again...assuming I get the facing operation working again. :lol:

My last issue has to do with tool offsets. I don’t know what I’m doing wrong but sometimes after going through the process (turn stock, set diameter, set X there, etc.), the value stored for the X offset is not right. It’s frequently a much larger value than it should be. After doing it over a time or two, it then is set correctly.

Make sure you do not have soft limits setup incorrectly. You might have them set smaller than your allowable travel.

I’m away from the machine right now but will post a report later tonight. I know I was rambling on but I did mention an MDI Z0 or Z-1, etc works and the tool will move there and not crash.

do you have internet connection at the CNCPC?

Check your tool offsets.

from the report.

travel limit value for X axis is set to -2.25"

X offset values for tool#1 are -2.13"

what diameter of stock did you turn down and measure or use to touch off of when setting X zero and Tool offsets?
