here is more info and pics
i made this with on old epson dot matrix printer.
in commercial cutters the pressure of blade determine depth of cut, but here i used a future of this printers for this purpose
in these printers u can set them for print multi layer paper (with stencil) by adjusting distance between printer head and lower roller, and what i have done is using this for adjusting depth of cut and if works nice
