Had a call yesterday from a friend asking me how to fix a problem with his g81 drill cycle.He stated that if you looked at the graphics in an iso view it looked like it was drawing a triangle.His program was a simple g81 with 4 holes in row.He also stated that if you changed to g83 it drilled ok.I checked his code,ran it here on the desk and it looked good,but I was using .028.Later I loaded .031 and it did what his was doing,immediately changed to .033 and it went away.Hope this helps anybody that has a g81 that draws triangles on the simulation screen.
Joe.
