I'm actually working on retiring a post right now labeled v3.05 MP Executable - intial post 09/01/92. Pretty close right now as it's a simple 2x lathe and a lot of it is just formatting, but in the beginning of the program I need to use a G50 to set my tool positions and set a speed clamp on the spindle, so as an example of the program I'm using for reference the first line should be: N10 G50 X190000 Z105000 S1500 The rest of the program has X formatted for diameter output, which I need, but the set position line and return home line specifically are outputting X95000 instead of X190000. The old post uses a global formula to scale xh$ to a diameter value every time it's referenced. Would this be acceptable/possible for modifying the Fanuc 2X Lathe post, or is there a more proper way of achieving that output?

I've sent my reseller a few emails and made a couple different phone calls...been kind of difficult getting a response from them for my post processor issues. I don't use wear comp for programming my lathes, only computer. And I've never seen the M98 P2 with the Mazaks or Cinturn.

Hey, thank you for your reply! I'm having issues on 4 lathes - 3 of them are 70/80s vintage Mazak with Fanuc 2000c control, plus 1 Cinturn with Acramatic 900TC. I feel like I might be able to increase the range for error on the Cinturn, but I'd say the Mazaks are stuck. The error I'll get will be something along the lines of "End point of circular interpolation is out of admissible range". I will PM you with one of the posts and some more information. Thanks again.

Hey guys - I'm a first timer posting here, and I've had similar topics with no true resolution posted on Mastercam.com and PM. Hoping some of you gurus might be able to give me a hand. Running Mastercam 2017. First issue (sorry, I don't believe this is post related) is with arc values on about 4 of my (old) lathes. N205 G03 X22229 Z77554 I0000 K-0156 N210 G01 X22428 Z77454 N215 G03 X22520 Z77344 I-0111 K-0111 Simply put, there's that .0001 difference in my K address that will lock up some of my machines. In the control def I changed my tolerances for NC precision, General math function and Max. deviation in calculated arc endpoints to 5 places behind the decimal. This seemed to clear up some of the discrepancies, but not all (if I change the radius of the insert it may post out okay, but may not). Is there any way to tighten this up? The second issue I'm frequently seeing for some of those same lathes is that when I put together roughing and finishing operations with the same tool, I'm having tool changes posted out without selecting the force tool change option. I wrote a program recently where I'm using 6 different grooving cycles to cut off 6 pieces on one program, and it's posted out to come in and rough, return home, drop offset, pick up offset, then return to finish/cut off, return home, drop offset, pick up offset, go to next rough, etc. I figured this is something related to the null tool change in the post, and I've tinkered with it with no luck thus far. If I need to send up a post processor or display some additional code I'm more than happy to oblige. If these topics have been covered I'm sorry that I missed them in the forum, and a redirect to the proper thread would be appreciated. Thanks so much everyone.
