Hey Andypugh and PCW. I will post another reply tomorrow but here is a email without any of the real usefull info like ini files.. But I have added two videos here that show the issue and then what seems to be the solution after I increased the P value from 50 to 500.
https://www.youtube.com/watch?v=ktnbOf2Kj4o video of errors gone on the machine <https://photos.app.goo.gl/bT9o9Ff4dx7pCMDQ9> Andypugh it was a Joint following error that was coming up on the Axis screen as a error and throws the E stop. I ended up increasing the P value in the INI file for each axis for the stepgen PID from 50 to 500 and the error seems to have gone away. I have also increased the Min ferror to 0.20 mm. Do you know what that will actually mean in actual machine use? eg will that affect my accuracy? That was after a whole bunch of stuffing around for hrs trying different values all over the place. But that may be the wrong way to do it... This video is 3 mins long so feel free to skip through it. I will try make a better video later on. video of errors gone on the machine <https://photos.app.goo.gl/bT9o9Ff4dx7pCMDQ9> Second question: "What is PID.n.maxerror set to? Is your FF1 correct? In a cruise, using halscope, you should see the velocity command and the actual velocity pretty much equal." I don't know if FF1 is correct. I have just left it as the default from Pncconf which is 1 And I haven't tried to view it in the Halscope. I will have a look later this week. PCW I will attach my Ini files tomorrow when I get back to the shed again. But I think FF1 was equal to "1" But you guys really need to see my ini file before we go any further. But I know it wasn't 0.0005. I am pretty sure it was 1. and the Min ferror I originally set up in Pncconf as .02 but then changed it to 0.20mm later on after I kept getting all these errors. When using the setting up the tuning in Pncconf the table was actually back driving itself. I would move the machine one direction and it would move and then turning around and try to come most of the way back to its start position. as you will see from the first video if you watch it. Apart from that I will check these other values and see what I have and I will post the Ini file here for you guys to check. once again thanks for the help guys.
