I'm trying to run a part on my 4th axis but this error comes up. I'm a good distance from the soft X limits (closest is ~140mm away). X0 is at -489mm in machine coords and the limit is set at -684mm. Here's the NC file: And my report: I have enabled 4th axis and am using Swissi's latest post (v005). I can move the table between X-50 and X50 from MDI but the program is upset with a move near X0.

Any ideas? Is there another limit hidden away somewhere? Help!!

### EDIT ###
I reposted the file using the previous Swissi post (v003) and it seems happy. This suggests either the post has an issue or (more likely) I've made a different setting in the user options. Not sure what's happening here.

E10 selects WCS #10, so after that point you are not longer using G54 (WCS #1).

WCS #10 has never been set, so it has an X axis offset of 0 (part zero is at machine zero). Therefore you get "907 X axis travel exceeded" on the first line that tries to move to a positive X coordinate.

Thanks for explaining, Marc.

As you may have seen, I found that the issue was specific to v005 of the post processor. That's not to say it's an error in that version of course - it may be that I have set user options differently between the 2 implementations, in a way that I haven't appreciated. Perhaps Swissi will clarify.

Certainly, I noticed that some of the work offsets were a bit questionable when sanity checking the tool position coords. Having said that, the displayed WCS coords looked right, which confused me.

V3 had a problem setting everything to G54 even when I wasn't supposed to. viewtopic.php?p=43875#p43875
