Run always as "Administrator Rights", it works for me.

I get that same problems, after working a time, my mastercam freezes, then a try Run it as "Administrator rights", it works. No more freezes.

if you look it, is on incremental too, if works for R value why didn´t work for deep, as i said the value in text box " Top of Solid" only is used for R values and not for deep calcs, for deep calcs it´s use the Z Value of the entity.

You are correct, but i also work on 3 axis and sometimes i need to only get the posision of a hole and put the deep value on incremental, but mastecam dont do it, as you can see on post above. Why Mastercam is ignoring the Textbox of "Top of Stock" on calcs to deep, but using it for the aproximate value (...R2...)?

CD or MD, translate please.

AS Goldorak said , using the 2D/3D mode wouild correct the problem, i tested and it dosen´t. After test various ways i found that mastercam hangs on z value of the point selected, even if you change the value o "Top of stock..." it ignors. Look this exemple: I selected a point with the z coordinate value of 100.00 mm, configure the toolpath (drill) like this: and i get this : G98 G81 Z98. R2. F100. Looks like Mastercam is ignoring the Value of "Top of Stock" . Can someone test? Drill_point.mcam

No. I just wont that mastercam calculate the real value, not incremental. If you work with 5 axis, you pick z value of a face and you wont drill a hole of 30mm deep, you put incremental of -30.mm, istead of calculating the value, last time i worked that way it was on Mastercam X7 to X9 and works fine.

I trying using drill toolpath with incremental dimensions but its not working . Se it : And my program outputs like this: ..... G81 X0 Y0 Z-3 R0 F50. instead of this: G81 X0 Y0 Z-5 R0 F50. I analise the nci file and the "-3" is there istead of -5. I try Mastercam 2019 and the same problem, even with another Post and machine. Cam someone know how to correct it?
