General Mach Discussion / help with tangential knife please
« on: March 20, 2006, 05:08:25 PM »
Hi All, Newbie here 
I am currently trying Mach 3 with a view to using it on my plotter/cutter.
I am assured by art that G2 / G3 moves now incorporate tangential control..they do but mine does not work correctly
for example.....I have drawn a circle inside a square using autocad....I import dxf using Mach 3...Fine, no probs here but:-
when i run the g code, the tangential control works correctly for the square but the direction of knife rotation is opposite to the move for the circle???
if i convert the dxf to hpgl and then import hpgl file using Mach 3, run the g code it all works OK, if a little jerky
what have I done wrong?? or is there a bug in the prog?
I would like to confirm it will work for me before i purchase full version....and another box of blades!!!!lol.
kind regards
Ian d.
