Important: for the inputs, an
"Enabled"
polarity corresponds to a normally
open (N.O.) circuit or switch; while a
"Disabled"
polarity corresponds to a
normally closed (N.C.) circuit.
Galaad receives from AxeMotion the eventual corrections or updates of the
firmware (the card internal program) for their CNC modules. Consequently, a
Galaad update may induce an
automatic firmware update
if the option is
ticked. You may also force the reload of the firmware if necessary.
The
data transfer
corresponds to the USB flow speed to the card. It should be
set to
"Very fast"
. That speed should not be change unless you experience
communication breakdowns due to electrical problems (noise generated by big
motors, neon lights,
etc.
). Also the
buffer overflow error trigger
should be set
to medium or low sensitivity. This error raises up when the automatic milling
goes faster than the transmission and therefore the buffer gets drained.
The
zero-end switches
correspond to the reset of the absolute co -ordinates,
i.e.
the machine zero, using a reference run. This re set is managed by Galaad
which must know the inputs that are connected to the end switches and their
polarity (normally closed or normally open).
Important:
if you do not know the inputs that correspond to the end -switches,
the command
"Parameters / Machine / I-O Test"
may help you find which
switch or sensor is connected to which input with which polarity. A normally
dark input that lights up when the switch is triggered corresponds to an
"En-
abled (NO)"
input. Reciprocally, if the input is normally light and darkens when
the switch is triggered, then the polarity is
"Disabled (NC)"
.
