  1. Hi, new to the forum, and pretty new to modifying the post. I've only helped my supervisor at previous company modify a post. First thing first, I've already backed up my current post. I'm want to modify the post for my MasterCAM Mill 2017. I am using a CNT Motion Router using WinCNC for conrtol at the machine. I have 2 issues to solve regarding this issue: 1. The WinCNC software does not read a typical D## after it reads a G41/G42 for offset. The tool comp size is automatically read when the tool is loaded. I cannot have any D## callouts in my program because it is not supported by WinCNC. (there is only 1 comp. size available for each tool) Can someone give insight on how to remove this from my post? 2. I also need to have my G40/G41/G42 on their own line in my program. How can I accomplish this? I've made all these changes to the program by hand and confirmed they work. I just need mastercam to post the automatically. Here is an example of what my post creates now: [1/8" SINGLE FLUTED SPIRAL END MILL] M5 T2 M3 G0 X7.749 Y11.3001 S17500 G0 Z.5 G1 Z.1225 F100. G1 X7.762 G1 G42 D2 X7.775 G3 X7.723 Y11.3001 I-.026 J0.

G1 G40 X7.7617 Y11.303 Here is an example of what I need: [1/8" SINGLE FLUTED SPIRAL END MILL] M5 T2 M3 G0 X7.749 Y11.3001 S17500 G0 Z.5 G1 Z.1225 F100. G1 X7.762 G42 G1 X7.775 G3 X7.723 Y11.3001 I-.026 J0. G3 X7.775 Y11.3001 I.026 J0. G3 X7.7743 Y11.3059 I-.026 J0. G40 G1 X7.7617 Y11.303
  2. I've been having a problem with cutter comp recently. I updated to X9 a few months ago and I don't remember seeing this before the update. I don't think I would have missed this in the NC (or when checking my parts). Basically, on contours with a single straight line, the toolpath combines the line geometry and the Lead Out. So an example of the code looks like this: T3M6G49 G0G90G57X3.492Y.3182 M8 G43H3Z.1S1500M3 Z.05 G1Z-.95F20. G41D33X3.6335Y.1768F10. G40X4.1568Y-.3465 G0Z.1 Notice there is no move between G41 and G40 where the actual line is. I attached two pictures. The first shows the backplot of the path. You can see the Lead In as the blue part of the line, but the red part of the line shows both the geometry move and the Lead Out as one step. The second picture shows my Lead In/Out page. Nothing fancy. Just a straight line. Sometimes I can change some parameters that shouldn't affect this at all, and it will fix the problem. Some examples: Change the plunge and feed rates so they are not the same. Un-check "Enter/exit at midpoint in closed contours". But sometimes those strategies don't help. I have tried using the "Adjust start/end of contour" option instead of Entry and Exit to no avail. I've checked my Configuration and Control Definition to no avail. It's not a problem with the post because I used three different machine posts and they all output the same code problem. Right now I'm stuck manually editing the NC or modifying my geometry. Any help on the issue would be appreciated. I'm probably missing something painfully obvious.
  3. Does anyone know how to change the post to output the cutter compensation to come on right after the G00 rapid command. Currently my post outputs it on the next line with the G01. Here is a sample code of what it looks like: N100 T0101 ( OD 55 DEG TNMG ) G99 G50 S2000 G96 S360 M03 G0 X.6 Z.087 M8 G0 X.5 Z.037 G71 U.1 R.02 G71 P102 Q104 U.01 W.004 F.01 N102 G0 X.245 S360 G1 G42 Z-.428 <-------- I need the G42 to be moved up to the line above in front of G0 ---=== X.2895 X.3095 Z-.438 Z-1.803 X.41 X.43 Z-1.813 Z-2.257 X.5 N104 G40 M9 G0 X8.
