<div class="markdown_content"><p>Hi tommyk-mar,</p> <p>do you call SMC_SmoothPath after SMC_NCIntepreter? Both G51 in the G-Code <em>and</em> the function block call are needed.</p> <p>You can see how this can be done in this example: <a href="https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_cnc_3.html" rel="nofollow">https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_cnc_3.html</a></p> <p>Best regarsd,</p> <p>Georg</p></div>

<div class="markdown_content"><p>Hello,<br/> Im using SMC_NCInterpreter and SMC_NCReadFile2 to read gcode program for CNC machine and what I have observed is that G51 and G52 is not smoothing the path. Machine stops in every point, what could I do to make machine pass through the points without stopping or what could allow me to use smooth path corretly if I use NCInterpreter.</p> <p>Im using it because I want to add variables to my gcode and its not possible directly from the CNC editor thats why I do use external file. <br/> Any ideas?</p></div>
