ENGRAVING PROBLEMS
Problem: Engraving on the plate is “slanted”.
Possible solutions:
1. Check material for squareness. Maybe your shear does not cut squarely.
2. Check to see if the material on the table is indeed at a true home and is square to your scale
bars or stops.
3. If your table is equipped with scale bars insure that they are secure and flush to your T-Slot
table.
Hint: Always inspect your job before removing your plate from the system. You may be able to
salvage it by re-engraving the job, or at a minimum, you may be able to analyze the problem and
prevent repeating it. Perhaps the plate moved during engraving. Removing it without inspection
would prevent you from detecting this problem.
Problem: You are using a nosecone, but your engraving is “shallow” across the top or left margin
of your plate. It engraves properly when the spindle is away from the edge.
Possible solutions:
1. Your nosecone is riding on the scale bars or side stops. Loosen and
lower the scale bars so that they are below the level of your material
surface. Retighten the thumbscrews.
2. Check to see if your material is riding on the scale bars or side stops. It’s not hard to miss
during set-up especially if the plate is thin material.
Problem: You are using a nosecone and your engraving is uneven.
Possible solutions:
1. Your spindle is not “zeroed” to your material. Follow the steps in “Chapter 4” to zero your
spindle.
2. You are not using enough float and need to adjust the down stroke until your nosecone
touches the material with some pressure.
3. You may be engraving too fast for the type of material you are cutting. Check the
manufacturer’s recommendation. The cutter may be bouncing on the surface. Some hard
materials may exhibit this problem.
4. You may have a defective or broken cutter. Replace it.
5. Your material may be defective.
6. Your vac chip removal system is plugged and engraving chips are caught between the
nosecone and the material.
7. The nosecone or vac nose is loose.
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 emory 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.
