Seedy Steve On Page 16 Like the "User defined name" under Toolpath group trick. I made mine T# (like to separate the different tools into tool path groups. Can you explain what "User defined name " does under NC File does?

Last week I drilled 10 micron (.004") holes 80 places in PTFE (Teflon) on my CNC bed mill. I used this simple 2inch light setter. Works fine and very accurate. http://www.penntoolco.com/spi-height-offset-gage-2-oal-0-200-head-diameter-13-156-5/?_vsrefdom=adwords&gclid=Cj0KCQjwsZ3kBRCnARIsAIuAV_RlhBHW2riFZDU998ptxPTwTR0pzPJZu4HQyRncmdXS0z0nAevso4oaAun8EALw_wcB

In X2 there is trim toolpath function. draw a rectangle "border" a little bigger than the stock,program 4 quadurants of the circle. then use trim toolpath to trim away any movement outside the rectange border

I have the same request,I have used other programs that adjust the feedrate with the above formula. It is very useful on older machines that don't have G107 option. I normally use the change at point (in geometry) I recall a post a while back that someone modified their post too use this formula on arcs.I dont like the adjust arcs feed (tool setting page)because it does it for the whole program (slows down roughin ops)I wish it was in each operation.
