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 atness by a few thousandths.

3. Parcel the job if possible so that you can have more direct control over the depth of each spe-

cic area. This may be effective if you have uneven material or a large engraving bed.

4. Table tolerances may not be able to maintain the accuracy level you want.

5. Table may not be on a level surface.

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 at material, a very at bed and some degree of skill and con-

dence. 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 in-

crease your table speed.

2. Your cutter is worn or damaged. Replace.

3. Turn down the dwell speed.

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. This problem is tough. Sometimes caused by dull cutters, the wrong cutter, or not enough over-

lap 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 un-

square cutter to the material surface.

5. Turn spindle speed up.

Problem: Poor letter quality.

Possible solutions:

1. You may be engraving too fast. Engraving quality improves with the right engraving and spindle

speeds.

2. If you are diamond drag engraving, you have too much down pressure or you are engraving too

deep. Also, check the grain of the material; it should be left to right.

3. You may have a worn or dull cutter.

4. Your material is not securely fastened to the table.

Probelm: Ragged Type.

Possible solutions:

1. If the quality of cut is ragged or exhibits steps, you may have play in the cutter.
