dowload the sheetcam trial
export as .hpgl - have a play with exporting as .dxf too,but you will have to hairline them and export as an earlier autocad version = hassle
layer 1 = pen1
post processor - change from the 1st = AB tube cutter to mach
when you set up the table.... when you home your machine, simply set the material in sheetcam 10mm away from the home of x and y 'the table' - don't run soft limits.
anyways, if you do choose this route, can you write some brains or whatgamacaulics so you can simply click a mach button on the corel tool bar and the g-code simply appears in a new mach screen ready to go. - :? its really tiresome exporting from corel, then running the same post processing for a similar pre-set set up..
