Troubleshooting

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 ush 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 dur-

ing 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 3” to zero your

spindle.

2. You are not using enough oat 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 lm 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.
