Whenever I try to run a program, I get a pop-up message splashed in front of the production window. It says, "Cannot start program. Probably, error in program! Press enter to continue." This is not an actual error or warning or whatever, so it does not have an error number nor get recorded in the logs. It occurs intermittently, regardless of which program I am running, and it prevents operation. I'm not running any background tasks.
I attempted a system image restore to a point that I knew worked, but had no success. I suspected a hardware issue, so I replaced the axis computer, the main computer, and the mass storage cartridge. None of those hardware changes helped. Even if it did work momentarily, the issue would return.
I'm also having a problem that's probably unrelated. Our robot drifts in manual mode, as if it were receiving a CCW twist from the joystick. The drift is most obvious with large increment moves. Replacing the TP had no effect. The thing is, we noticed this problem just before we started having the "probably error" problem. It could have been occurring for a long time before we noticed, but maybe it's actually related?
Can somebody please point me to the source of this problem?
