I use ballscrews driven directly and I can push the axes and make the screws turn.
I am now thinking I may have a problem with either the drive power supply or the servo power supply. I talked to RutexUS and it doesn't make sense that two of the drives are acting up at the same time. At this point I don't know why either power supply would be intermittent. At least I have something to check. If anyone else has ideas, let me know. I'd much rather be checking several things than have no idea what's wrong.
I figure I need to run the machine and put a voltmeter on the both power supplies and see what happens as I run it. |
