Thanks for that, Tweakie. "F Engrave"? tell me more. I have been painstakingly using LazyCAM for years, and having to manually re-order the cutting order of each line of each character in order to force the machine to engrave in the same manner it would do if it were actually text. The reason being, that while text can be engraved, it always comes in as an outline of the characters. Which is fine, as long as the desired characters to be engraved are a minimum of 1" in height. But rather useless, when the desired characters are only 1/8" in height. The double-lines created in a character outline tends to result in an unrecognizable hole being drilled into the wood.
THANK YOU for trying the G code, to verify that it is correct! I am still no closer to diagnosing the problem. The tool parameters for the engraving bit, takes .008" per pass. So, with a starting depth of -.420" to a cutting depth of -.452" it actually makes 5 passes per character segment line. As you can see, in the photo of the actual engraving, the vertical lines of the character segment of the center T and E letters, seem to be "stepping to the left" with each pass. This is ONLY happening with just those two letters. As you can also see in the photo, the repeated runs of the engraving has resulted in repeated engravings of ALL other letters with absolute precision! My thoughts now, are that perhaps the lead screw on the X axis has some sort of wear in this area, allowing machine vibrations to cause the router to "drift" from right to left, during carving. But again, WHY does it only happen in this area (which only measures about 1/2" to 5/8" wide)? Inspecting the lead screw, does not reveal anything, so?
? Perhaps an excorcism is in order....
