i was reading an earlier post and someone mentioned that G41 could be used with P.125 instead of a D word for cutter radius compensation.  if i read this right and if it is true, would someone please post a program of simple 1" square with G41 used in proper syntax.  i was told that my techno Davinci router and the proprietary controller software did not support G41 G42.  i want to test it.  I am having a terrible time with this particular gcode as i have no idea where i should put the table with the D parameter in it.  not had any luck find resources online for this and the books i have assume more knowledge than i have.
thanks.

Hope this helps you
