Working in CNC12 Lathe I programed my 1st test part which is a very small part and getting an error regarding exceeding the travel in X line 16 Can someone give me a general idea of what it is, how to avoid it, and how to resolve it when you get this error?
Here is a report just in case you need it.

Re: Exceeding travel
You'll need to post the Intercon file as well so we can see what line 16 was. Normally, travel exceeded errors occur because of incorrect WCS settings or tool offset issues.
Cheers,

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Re: Exceeding travel
The post file is coming out of Fusion 360, here is the file.
Can you recommend a free NC viewer, have one on my computer at work but cant remember what its called. txt docs do not show line numbers that I can see

Re: Exceeding travel
From your report:
So all of your available axis travel is in the minus direction from home (which is generally as it should be), but you have your G28 return point set to the plus side of home on both axes.
That means that any attempt to go to the G28 return point (as is usually done for tool changes, etc.) is a request to go outside the travel limits.
Given the CNC program you posted, I would have expected the "907 X axis travel exceeded" error to occur on line 5, not line 16.
Set your Z and X values under the G28 return point to zeros, or to negative numbers if desired:
F1/Setup -> F1/Part -> F9/WCS -> F1/Return
Code: Select all
CNC12 v. 4.64 coordinates file
Axis Minus Plus Return Return Return Return
Limit Limit #1(G28) #2(G30) #3 #4
Z -8.5000 0.0000 3.50000 0.00000 0.00000 0.00000
X -12.7000 0.0000 4.00000 0.00000 0.00000 0.00000

Re: Exceeding travel
A couple of other bits of info.
I did notice today when the error popped up it said line 5 THEN it said line 16 I did not think much of it, but you saying that jogged my memory of it. Another thing is, this is a gang tool lathe if it matters at this point I have only one tool being posted at this point in that file.
My progress tonight is a follows
I went through the tool offset procedure again tonight to make sure I did it right.
Changed the G28 to X0 Z0,
loaded and reposted the file and now I'm getting exceeding travel in Z as well as per your prediction cncsnw. see screen shot
Still getting error on line 14

Re: Exceeding travel
For WCS #1, there is no offset in Z, and your Z limits are set to -8.5 and 0, and tool 13 has no Z-axis offset, so your maximum movement in the positive direction is 0. Line 14 has you trying to move to Z0.0758 which exceeds your travel in the Z positive direction.
It's usually not a good idea to ignore errors when they pop up.

Re: Exceeding travel
I will go go threw it again. Tool 13 for now is my reference tool.

Re: Exceeding travel
graph the part before running it, the graph is a true g code backplot and it takes into account travels etc.. and will tell you about any issues before you actually run the job.

Re: Exceeding travel
Without seeing exactly how you do your tool setting it's hard to say for sure that it is right or wrong. This could be a problem with setting your WCS and not your tools. I'm leaning that way since there is no Z offset in your current WCS in the above photo with the error.
Cheers,
Tom

Re: Exceeding travel
I'm doing the offsets as per the manual (skim cut method), I only have 2 tools set up an OD tool and parting tool, tool 13 is my reference tool thus no offset.
Might as well go over my settings to make sure my machine is set up correctly. Also a pic of my machine to show it in the home position.
