Y exceeded travel.

[beebee]

Got a frustrating problem. I have a part 8.25 x 14 inches. The long dimension
Is in line with the y axis. I get a error at line 176 the y axis exceeded travel.
Cant under the reason my y axis has total travel of 50 inches. And part is 14 inches. This was working then I made some changes to the code and now it’s not.

travel exceed message is telling you that the g code is requesting to move out side of the travel limits and its telling you the line number of the g code that this is going to occur saving you from ruining a part. . since you didn't post the offending g code program and a fresh report.zip , i would just be guessing at any of the 100's of possibilities that might be causing this message to appear. but , in general if the line is a Z axis move line 99% chance that the z zero position is set wrong or the tool offset is wrong or wrong tool number is being called.
if line is a XY move then 99% chance part zero is not set right and or WCS being used or called is not set right.

theses are easy to solve. take a breath and look at the graph, the graph tells you where the programmed and actual zero point is, move the tool to that point on the machine look at the DRO position and think about it.

Ok. I homed the machine and then jogged to the start location for the part.
Then set part zero for all axis. I looked at the dro . The x z were at zero. The y was
-15.
Then redid the part zero. This time the dro displays zero for the y The part ran with no errors.
I’m uncertain why the part zero set up didn’t work the first time.

Almost always not setting your part zero correctly. (Provided your soft limits are set correctly)
Get in the habit of pressing F8 Graph before running the job. CNC12 will go through the program and tell you the line number where the error occurs.
If it graphs the part with no error, you should be good to go.

Part origin is the number 1 thing to look at.

Also depending on how close you are to the end, any other moves, like lead in or lead outs also need to be taking into account.

And cutter comp.

Easy to figure out, since it tells you at which line it happens.

Try to move to this position and the DRO will tell you whats missing. Replace the part, set origin and run.
