Troubleshooting
2. We use a case management database system to track problems. Be sure to inform Technical
Support if the problem was experienced before, as this allows us to review the history of the
mill. If possible, please have case management number ready.
3. If the mill was purchased from someone else, please have that person’s name available. This
way we can reference the specic machine in our case management database system and
idenfy any problems the previous owner experienced.
4. Analyze changes that occured since mill last worked correctly and have that informaon available.
5. Review the troubleshoong-related subsystem you are having problems with to gain a beer
understanding of that subsystem.
6. Make sure you can repeat the problem(s). Do this several mes and record the results to
determine if you can repeat the problem(s) exactly.
7. Record any pernent informaon from the Status screen and have it available.
8. Try to dene the problem as clearly and concisely as possible by wring it down. Oen mes
by doing this you may help pinpoint the problem or nd the soluon to the problem yourself.
9. Consider sending Technical Support an email rst, as this may help dene the problem beer.
Communicang via email has the added benet of documenng the issue, thus eliminang
the need to interpret any hasly transcribed notes made during the phone conversaon later
on. Even if you do need to speak with Technical Support, sending an email rst can help the
conversaon go more smoothly.

10.3 Frequently Found Problems
There are several frequently found problems with all electromechanical machinery including the
PCNC mills. It is not that the problems are frequent, but among the problems that have occurred,
these are more frequent than others. The rst four items in this list fall into the category of machinery
in general, while the last item is specic to PCNC mills. These frequently found problems are important
to keep in mind when troubleshoong.
10.3.1 Loose Wires
Try as we might, it seems that on occasion we nd a poor wire connecon. This can be the wire in a
screw clamp terminal where the clamp is loose, or a problem with a crimp spade or ring connector
where the connector is ght in the screw clamp terminal but the wire is loose in the crimp connector.
This is most frequently found during the inial startup of the mill. The vibraon that occurs during
travel tends to loosen connecons. In this case, use the two nger pull test: grasp the wire close to
its terminaon point between your thumb and index nger, and gently but rmly tug each wire. If
the wire comes loose, re-terminate it before moving on to other wires.
