plasma cutters have all the same issues about a curved cutting

through thicker material. Remember the KISS motto... You have to
limit
your feed rate to give the waterjet time to cut through. As you
will
only cutting 2D profiles, you need something that can convert a
DXF
profile into G-Code. Rasterfratz works for me for 2D cutting and
engraving letters converted from true-type fonts. You will need a
CAM
package that supports lead-in so you can cut a clean edge after
you've
penetrated the material.

Hi Peter,
I do have deskcnc and it's good enough for this, but water jets
needs a good cam that can look way ahead and predicts what is going
to happen and than starts to adjust the feed rate before it gets to
a corner or radius to compensate for Jet lag doing that manualy
would be a pain if not impossible.
Got a quote from PEPs and it runs at 10K US$ (ouch !!)
I've being thinking about getting a working G code, than work this
out on excel to adjust the feed rate.
