SYMPTOM 1:
THE BOARD DOES NOT RELAY THE SIGNAL.
POSSIBLE CAUSE
POSSIBLE SOLUTIONS
-
Pin conflict or mach3 configuration
.
It is possible that the port address
used for the pin is not right, or that
there is a pin conflict with the. That is
that you are using that same pin twice.
(it could be assigned to a different
function).
-
Go to the device manager in windows,
and check the memory address used for
the parallel port you are using. Usually it
will be 378 for LPT1. Check also that
the port does not have a conflict. Then
in mach3, go to Ports & Pins / Port Setup
and Axis Selection. Check the memory
address is correct.
-
Check that the pin you are using is not
been used anywhere else in your setup.
Got to motor output and output signals,
and check all the entries.
-
The board does not like the
waveform it is getting.
Some
breakout boards could invert the
signals or modify the pulse width.
Changing the active low status of the
pin used also inverts the waveform.
-
Play with the active low status of the pin
used for the frequency.
-
The signal or frequencies are not
getting to the board.
It could be the
cable or that you are passing the
signal through the same breakout
board that you are enabling/disabling,
so the outputs could be disabled, so
they will not get to the breakout board.
-
Try a different cable.
-
Test the pins in the cable (before they
reach the breakout board) with a
multimeter.
-
Problems
with
Mach3
Pulse
Generation.
Mach3 could have
installation problems (you did not
restart immediately after installation),
or there could be something creating a
conflict. Some dongle devices might
cause
this,
other
software,
like
QuickTime or drivers for touch screen.
-
Test this in a different PC.
