chrisvk Posted March 23, 2022 Share Posted March 23, 2022 Wondering if anyone else has had this issue before. The x-axis in our 5 axis cnc lags behind by about a millimeter when following the TCP. The motor position shows a 1mm following error which makes me think it knows where its supposed to be but isnt keeping up for some reason. We tried adjusting the tuning and proportional gain settings which slightly decreased the error but its still to big for the applications we need. tcp_lag.MOV Quote Link to comment Share on other sites More sharing options...
robodavo Posted March 24, 2022 Share Posted March 24, 2022 Are you are using Ethercat drives with cyclic position… if so, do you have a position filter set in the drive? This will delay the target position in the drive slightly. It is good to use a very small value of you have a filter turned on. Quote Link to comment Share on other sites More sharing options...
