Chapter 6 - Troubleshooting 65
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.
Problem: Ragged Type.
Possible solutions:
1. If the quality of cut is ragged or exhibits steps, you may have play in the cutter
.
This
could be in the gap between the cutter and the spindle shaft. Maybe the shaft is worn or
the spindle bearings need to be replaced. Once a shaft starts to wear and a cutter is
loose, the problem can worsen quickly.
2. The spindle is loose in the housing or block.
3. The carriage is loose or has excessive play, check the z-axis bearings or slide.
4. Lubricate lead screws with recommended lubricant as explained in Chapter 5 -
Lubrication.
Problem: My baseline is off.
Possible solutions:
1. You’re not at the mechanical or software home. Maybe the table or carriage was
bumped during set-up. Maybe the previous job was cut short and the system did not
return back to its mechanical home or limit switches. Move the table, bridge or carriage
physically to home or send it home via the software.
2. Check your software layout for keystroke errors.
Problem: While burnishing aluminum I have voids or non-engraved areas.
Possible solutions:
1. Try re-engraving the same plate again. Some of the anodized aluminum plates have
very hard surfaces and two passes are required.
2. Switch to a diamond burnisher. The more common carbide tools may have difficulty
getting through the tough surface and are more easily worn down, thus sometimes
skipping across the surface.
3. Increase the pressure of the z-axis or burnishing adapter.
4. Try other materials. Same reasons as above. Some materials, from some vendors, are
just plain tough.
Hints:
Always try to solve the problems yourself before seeking help. A little patience goes a long
way. Never work on any problem that gets you so frustrated that you become irritated at
the machine, the service technician, or the salesman. It’s only a machine, don’t let it get
the best of you. Contact your dealer.
