Hi Stefano
I'm having an issue with the wing slot option using a MH42 airfoil. The chord length is 169mm but when I cut it comes out smaller at 145mm. I've checked on both Mach3 and LinuxCNC and both produce the same. I've made everything else OK all the blocks have come out perfect and match the print outs. I exported the cut path to a dxf and loaded into Draftsight and that confirms its only 145mm. Am I doing something wrong or is there a bug. I cut the tail slot and that worked fine but that is only rectangular.
As a test I changed the wingslot to a rectangle of 8mm and when exported to a dxf that comes out at 166mm, I supect 3mm is in the kerf. So it looks like there is an issue using a dat file. I exported the dat file from Profili2 Pro and aslo tried one from http://airfoiltools.com/airfoil/details?airfoil=mh42-il
Hope you can help
Keith
