I have a TSV60, the set-up might take a while to get to your own liking.
Here is how mine is set up :
- scoring blade to maximum depth, this is a V shaped blade so this makes the groove as wide and deep as possible to stop the junk that you find in melamine board being pulled up and causing chip out
- blade should be plunged to depth of work plus gullet depth, as a rough guide on 19mm stock, blade will be plunged to just under 30mm
- do loads of test cuts and slowly move the main blade cut over to the left of the V groove until it just stars microchipping, then move it back a notch, in reality you are moving the scoring blade to the right, but this is easier to explain
Since mine has been set up, I have not touched the settings, I use it and it works. The off-cut chips out with how I have mine set-up, this might not work for you, my goal was to have top and bottom chip free with one pass.
