Determining the values of the FlexCut parameters can be divided into two main steps. The first
step is to determine the ‘fixed’ pressure values. The second step is determining empirically the
length parameters.
➢
Step 1
First, go to the knife pressure test as described in section 1.6.1.3. Determine the pressure that
is needed to cut completely through both the vinyl and the backing. Make sure the pressure is
not set too high and the knife is not turned out too far. After the required pressure is
determined, raise the knife a little bit to check if it still cuts completely through. If this is the
case, raise it a little more. If it does not cut completely through anymore, then lower the knife
again. Now lower the knife pressure a little bit to check if it still cuts completely through. If this
is the case, lower the pressure a little. If it does not cut completely through, set the pressure
at the previous value.
This is how the correct pressure to cut completely through the media is determined, as well as
the correct amount the knife is turned out.
NOTE: Write down the pressure that was needed to cut completely through and
do not change the physical knife depth anymore (unless the knife has worn down
a little bit).
Now set the knife pressure correctly to cut only through the vinyl. Write down this value.
➢
Step 2
Set the FlexCut parameters as explained in section 2.6.1 with the following values:
•
Full pressure
: the value that was needed to cut completely through the media (determined
in step 1).
•
Flex pressure
: the value needed to cut through the vinyl only.
NOTE: We do not recommend using cutting speeds larger than 400 mm/s (16
ips) with cutting pressures above 170 gr. So, if the full pressure is larger, lower
the FlexCut velocity.
•
Full pressure cut length
: 10 mm.
•
Flex pressure cut length
: 0.8 mm.
Perform a test. Check the bridges. If they are too large, perform a test with a lower
Flex
pressure cut length
value. If the bridges are too small (or non-existent) then raise this value.
The FlexCut parameters are now set. If these settings need to be adjusted, try only changing
Flex pressure cut length
. There is no need to adjust pressure settings unless the knife wears
down. In that case, start again with step 1.
