Hi Fless, thanks for your report! We created an issue in our bug tracker (SM-5109) and will have a look at this issue. Best regards, Georg

Hi k2saki, 1.SMC_ReadNCFile2 2.SMC_Interpreter 3.SMC_SmoothMerge 4.SMC_SmoothPath 5.SMC_CheckVelocities I attached a simple example project. Best regards, Georg

Hi kumareasu, yes, correct. Best regards, Georg

Hi niallel, yes, you are right, Cams would be the preferred mechanism. Best regards, Georg

Hi peterned, the start position given in the CNC properties is only used if you use the compile mode OutQueue. With compile mode SMC_CNC_REF, you need to provide the start position in the IEC application. The function block SMC_NCInterpreter has an input piStartPosition. You can initialize it with the output of the forward kinematic transormation FB for your machine. In your case probably SMC_TRAFOF_Gantry2. Best regards, Georg

Hi jonasz, you already solved it, I'm answering here for the sake of others with a similar question. You can provide the slope of the A/B/C axis with the U/V/W word. See example 3 here: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cnc_din66025_additional_axis.html If you don't want to change the G-Code, the function block SMC_RecomputeABCSlopes can compute the slopes automatically. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/SoftMotion-Function-Blocks/SMC_RecomputeABCSlopes.html...

Hi k2saki, I would recommend to have a look at SMC_SmoothMerge, followed by SMC_SmoothPath. SmoothMerge will combine the small G1 elements to longer splines, SmoothPath will avoid stops between the splines. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/SoftMotion-Function-Blocks/SMC_SmoothMerge.html For SmoothMerge to work, you have to configure a tolerance, i.e. by how much it may deviate from the lines. To graph the output of the interpolator, you can use...
