64 VE810 Engraver Manual
Problem: ”Shadowing“ occurs while engraving certain materials.
Possible solutions:
1. Leave the protective film on the engraving material during engraving.
2. Use a plastic nosecone instead of a metal one.
3. The nosecone may be damaged. Inspect for burrs or roughness. Try using an emery
cloth to polish the nose.
4. Back off on the spring pressure. Excessive down pressure will leave a rub mark on
almost any plastic material.
Problem: You are not using a nosecone and you have uneven engraving.
Possible solutions:
1. Switch to a nose-riding method.
2. Use a different method of holding the material. If you use double-sided tape, it may be
thick enough to change your surface flatness by a few thousandths.
3. Table tolerances may not be able to maintain the accuracy level you want.
4. Table may not be on a level surface.
5. Make sure the Pressure knob is locked all the way down.
Hint: While it’s true that you can do non-nose riding engraving, it’s not easy to hold any
controlled accuracy on the depth. This takes flat material, a very flat bed and some
degree of skill and confidence. It also takes an application where some amount of uneven
engraving may be tolerated.
Problem: I’m getting ”tails“ or ”swirls“ in the corners of my engraving.
Possible solutions:
1. Your cutter speed is too fast relative to your x-y speed. Slow your spindle speed down
or increase your table speed.
2. Your cutter is worn or damaged. Replace or have re-sharpened.
Problem: I’m getting ”fuzz“, ”fur“ or can see lines in the bottom of my cut showing each
cutter path. I can even see steps in the bottom of my cut.
Possible solutions:
1. Sometimes caused by dull cutters, the wrong cutter, or not enough overlap for each cut.
Try changing cutter size slightly. You may get better clean up.
2. Try taking a second pass cut at .001-.002 deeper. This may clean up the roughness.
3. Resharpen the cutter. There are various cutter angles that can cause these kinds of
problems. There is a relief angle that if too great can cause noticeable ridges in the
bottom of the cut.
4. Ensure that the spindle is square in the mount or block. An unsquare spindle means an
unsquare cutter to the material surface.
5. Turn the spindle speed up.
