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 2.2.2. Determine the pressure,
needed to cut completely through both vinyl and backing. Make sure the pressure is not set
too high and the knife is not turned out too far.
After the needed pressure is determined, raise the knife a little bit to check if it still cuts
completely through. If this is the case, do this again. If it does not cut completely through,
then turn the knife out as it was.
Now lower the knife pressure a little bit to check if it still cuts completely through. If this is the
case, lower it again a little bit. If it is not the case, set it 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 just through the vinyl. Also, write down this value.
Step 2
Go to the FlexCut parameter setting menu as described in section 2.6.1. Set the full pressure
parameter to the value that was needed to cut completely through the media (determined in
step 1) and set the FlexCut pressure to the value needed to cut just through the vinyl.
NOTE:
It is never recommended to use 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.
Now go to the full pressure length parameter and set this to 10 mm. Go to the FlexCut pressure
length and set this one to 0.8 mm. Perform a test. Check the bridges. If they are too large,
perform a test with a lower value. If they are too small (or non-existent) then raise this value.
The FlexCut parameters are now set.
If these settings need to be adjusted, try with only changing the FlexCut pressure length. There
is no need to adjust pressure settings unless the knife wears down. In that case, start again
with step 1.
NOTE:
It is not always easy to find the correct balance between cutting deep
enough and making sure the pieces can be taken out easily and not cutting too
deep, making sure the material keeps its strength while cutting. Sometimes this
balance doesn’t exist, meaning that this material can’t be cut through with
satisfactory result.
