I have a Miyano JNC-60 that lost all the parameters. I put in all the paramaters back in to factory defaults. My X axis motor has become unstable. It's like it's drifting down and then the motor kicks in to bring it back. And then the pulsating slowly gets worse until it faults out. I've tried adjusting the servo loop gain (1825). I got it to were it works for a while, but still eventually errors out. Any other parameters I should try adjusting?
