The help says VAR_GENERIC exists, but trying to use it in 3.5.21.30 results in a unknown token error. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_vartypes_var_generic_constant.html Did this feature get removed or is there something else that needs to be done to enable using generic function blocks?

@davidking, can you be more specific about where exactly "Compiler Defines" is located. I'm using Codesys v3.5 SP21 Patch2 and cannot find this Compiler Defines option. In the menu Project -> Project Settings there are Compiler options and Compiler warnings, but that is not it.

Hi George - ok thanks - but who created this FB in the first place? Could you lead me to the creator company? Is CODESYS not the old S3 that created this FB? :-)

Instead of using scaling of 150%, can't you adjust your diplay resolution (Windows+i keys, then go to System > Display settings)?

Hi! Does anyone have an example of ReadNCFile2 with Sentence Modifier? Current examples on CODESYS help page are outdated and have a lot of errors, like "SMC_CNC_LibParams.MAX_SUBPROGRAM_NESTING_DEPTH" calls, which are not present in current version of SMC3_CNC library.

Hi tommyk-mar, do you call SMC_SmoothPath after SMC_NCIntepreter? Both G51 in the G-Code and the function block call are needed. You can see how this can be done in this example: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_cnc_3.html Best regarsd, Georg
