3. The T-slot table may not be flat, or has been installed improperly.
4. The table the machine is sitting on may not be a level surface.
5. Make sure the spindle spring 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 table and some degree of skill and
confidence. It also takes an application where some amount of uneven engraving may be tolerated.
Problem: There are ”tails“ or ”swirls“ in the corners of my engraving.
Possible solutions:
1. The cutter speed is too fast relative to your X-Y speed. Slow your spindle speed down or increase
your table speed.
2. The cutter is worn or damaged. Replace it, or have it re-sharpened.
Problem: There is ”fuzz“, ”fur“ or lines in the bottom of my cut showing each cutter path. Steps are
noticeable in the bottom of the cut.
Possible solutions:
1. This can be 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 out of square spindle means the cutter is
not perpendicular to the material surface.
5. Turn the spindle RPM speed up.
Problem: Poor letter quality.
Possible solutions:
1. The engraving speed may be too fast. Engraving quality improves with the right engraving and spindle
speeds.
2. When diamond drag engraving, there may be too much down pressure. Check the grain of the
material; it should be left to right.
3. The cutter may be dull or worn.
4. The material is not securely fastened to the table.
Problem: Ragged engraved characters.
Possible solutions:
1. If the quality of cut is ragged or exhibits steps, there may be 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 the lead screws as explained in the Maintenance section.
Problem: My baseline is off.
Possible solutions:
1. The machine's home position may have changed. The table or carriage may have been 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 errors.
Problem: While burnishing anodized aluminum, I have voids or non-engraved areas.
Possible solutions:
1. Try re-engraving the same plate again. Some anodized aluminum plates have a very hard surface
and two passes are required.
2. Switch to a diamond burnisher. The more common carbide tools may have difficulty getting through
