I have found that turning off lead in / rad in on any profile will issue a G41 or G42 on an arc if starting from the center or a position off of the profile. I use this op only for deburring operations, where its starting on the profile, otherwise, I always use a minimal 0.01 for both parameters and this avoids the issues of radial cutter comp.

I have built libraries also, although I need to convert many from my V9.1 to X6. The only issue I run into from time to time, is that when under pressure to get a program complete, specifically utilizing a horizontal machining center, is resetting all of the imported planes to match the existing machining view(s). Without doubt its faster, but caution must be exercised not to skip over parameter(s) specifics prior to posting.

After completing two MasterCam classes and with my instructor praising mpmaster, ( he was a great instructor) I decided to try it out. My current post works well, although I wanted to see what mpmaster has that's better. What I found out already is a problem with the B-Axis rotation. This could simply be an adjustment, although I do not know where to look. The following code is a snippet form my current post and mpmaster in which the b-axis is a problem because I need a M62 on the same line as the "B" call out, followed up with a "M61" on the next line. The second issue is the transform-rotate which does not post a "B" movement or M62 call out. Thank you in advance for clarifications to this issue.

In X5 there is a large selection of adjustable drilling parameters found in "custom cycles" to where you can adjust all of your peck requirements. I hope this helps.
