Please disregard, the problem was my own - I was trying to modify the incorrect post that was not linked to the program. I have added the lines needed to the correct post and it is working now. Sorry for any confusion.

Hi, I am attempting to add a bar feed command through our current post setup using the "stock advance" feature in mastercam. I've gotten most everything ironed out so far, but can't seem to make anything work for the needed bar feed command. We have been hand coding it up until now, and only require the following: M69 Chuck Un-Clamp M51 Bar feed command M68 Clamp I am using the Stock advance feature, but was questioning whether using the canned text would be a better option since its three lines and I want it to follow after the part-off tool. Either way, it doesn't matter to me as long as we can generate code that works. I can furnish any other information needed. Thanks for the help! -Bret Here is a sample of whats being output currently: T0200 M01M00 (Push stock - from Left Spindle)G50 S2500G30 U0 W0T0909 G97 S716 M03(TOOL - 9 OFFSET - 9)

Thanks for the input everyone! I just tried turning the comp off - no change in output I tried adjusting comp from left to right and vice versa with comp on and off - no change in output This lathe is basically a glorified engine lathe with servo motors installed - it uses a standard Aloris tool post. When I enter my value (in this instance .01") into the box (stock I want to leave in X) in mastercam, it generates the actual lines of code down at the lower left of the screen (or at least what should be the correct lines). But when I go to process, they generate incorrect. I notice above that box it states: "The actual NC Output depends on the post processor". Is there a value in the post that controls whether it generates as a positive or negative value? If I enter the a negative value in mastercam for what I want to leave - it generates as a positive value. For right now - I will just cheat and change the program to suit - but I would like to get this figured out. Once again, Thanks for the help! Bret

Hi, I put together a program with a rough canned cycle for cutting the OD of a part on our HAAS TL-1, but when I go to post the program - it outputs opposite of what I want. I enter that I would like to leave .010" per side on the part for finishing in the "Stock to leave in X (U)" box, but instead I get the coding below. This is useable as is with some manual modification, but I would like to correct the problem so in the future it will output correctly. I've also attached a screen shot of mastercam prior to generating this code.
