Bear with me as I don't have the technical knowledge that a lot of you do. I converted a ticker tape NC machine to M3 and have it running G-code programs however it will fault out at random instances and I am not sure why. I am thinking I need to do some more tuning either in the M3 motor tuning page or with the PID adjustments on the drives but am not sure. Does anyone here have a recommendation on where I should look for motor specs and how I can apply them to motor tuning in M3? Also is there a way to be in the motor tuning page and activate the jog feature or am I always going to have to save, close the page and then go back in to make additional adjustments? This machine has some jumbo sized servos on it and I am wondering if I am limited by the Geckos to their speed, right now I have my velocity set at 80 inch and acceleration will go no higher than 5 inch and I think the acceleration is low. I can get more velocity out of it but the velocity when pushed higher will get me and external E-stop request. My machine is a belt drive setup from the servo to the screw and to this point I have been unable to get my O-scope to read any signals out of the drives so the PID tuning has all been done by ear which makes me think that may also be a problem as I am not sure if the gain setting is correct however the machine will run smoothly it just randomly faults out (roughly 4000 lines of code). Any help is greatly appreciated.
