<div class="markdown_content"><p>thank you for the reply, but how do you modify precision?<br/> Do you mean the Extras / Set epsilon values... menu, or something else?</p></div>

<div class="markdown_content"><p>Hi,</p> <p>I have a CNC program (attached) created with DXF import. It works fine.<br/> But if I add a pair of G52(round path) - G50(end of round path) commands to it and try to save it (Write CNC program to file), Codesys 2.3 displays the following message</p> <hr/> <h2 id="error-during-interpolation">Error during interpolation</h2> <p>The program causes the following error while interpolating:<br/> Too many recursions in the interpolator<br/> Cancel Saving?</p> <hr/> <h2 id="yes-no">Yes No</h2> <p>Then if I execute the CNC program, it is processed OK - angles are rounded, drives follow the path, everything looks fine....... but M-commands are not executed. <br/> If I remove the G52 / G50 commands, everything goes back to normal and M-commands are processed.</p> <p>Any idea why this happens? Are the PLC resources insufficient to handle the path with roundings? <br/> And more important, is there any way to handle this?</p> <p>Thanks for any suggestions.</p> <p>--<br/> I use Codesys 2.3.9.42 provided by Festo, with Festo PLC CPX-CEC-M1</p> <p><a class="" href="https://forum.codesys.com//download/file.php?id=2150" rel="nofollow">CNC_test.txt <span><span>[2.53 KiB]</span></span></a></p></div>
