Checking The Different Components - Trotec Speedy C12 Service Manual

Checking the different components:

Some components can be checked easily by performing only a few steps. These
tests are described here. Additionally a lot of electronic problems can be recognized
in the engraving result.
How to check the power supply
Open the service access panel and the cover of the electronic compartment.
Switch on the machine. Make sure that there is net voltage on connector X11
(between pin 1 and 2). Measure the output voltage at connector X 23. It must be
close to 30V DC.
How to check the transformer
Open the service access panel and the cover of the electronic compartment.
Switch on the machine. Make sure that there is net voltage on connector X16
(between pin 1 and 2). Measure the output voltage at the output of the transformer. It
must be close to 12V AC.
How to check the Motorprints
Whenever you think there is a problem with one of the motorprints (e.g. because one
of the axes doesn´t reference) then replace two of the boards for t he different axes
(all of them are identical). If then suddenly the axis that has previously shown a
problem works fine, you know that only the motorprint shows a problem and must be
replaced.
