Dave, Alan, Andy, Thanks for the replies. I have read all of those things too. I would reiterate that this is something that occurs very rarely, but when it does happen it is very damaging. I have two basically identical machines which have been running for the last 7-9 months, and this problem has only occurred a handful of times over that span.
It is also easily remedied in the G-Code, but the application is basically a once and done type, which means I need to in some way anticipate the conditions under which it occurs. My current brute force approach is to insert an additional line of G-code between consecutive G0 moves any time the distance of the first G0 move exceeds some threshold. Even though 99.9999% of the time, the extra line of code is superfluous. But without being able to quantify exactly when it will occur, there is no guarantee that my brute force fix will in fact prevent it from occurring under any circumstance. Regards, Eric For rapid linear motion, program G0 X- Y- Z- A- B- C-, where all the axis words are optional, except that at least one must be used. The G0 is optional if the current motion mode is G0. This will produce coordinated linear motion to the destination point at the current traverse rate (or slower if the machine will not go that fast). It is expected that cutting will not take place when a G0 command is executing. It is an error if: . all axis words are omitted. If cutter radius compensation is active, the motion will differ from the above; see Appendix B. If G53 is programmed on the same line, the motion will also differ; see Section 3.5.12. Somehow the definition and the described motion don't seem to match.
