I'm totally stuck in fixing my K2. Brief history of the machine. Purchased in '08 it was never put into service until earlier this year. It was purchased when K2 first started providing servo drives instead of just steppers. It spent several years in storage. I greased everything and it was acting pretty good for the handful of short jobs I threw at it. However... It has become completely unreliable.

I have done troubleshooting and moving any axis will cause the error. In fact I removed the x assembly from the ball screw and it will error moving the ball screw with nothing connected. I'm using Gecko G320 Brush Servo Drives. They are designed to error if the motors draw too much current, OR if the encoder fails behind the requested position. The three drives are wired in a way that if any one of them fail, they are all halted, which on the surface sounds reasonable, but there is no way to determine which axis failed, or just as important, why it failed... The speed is 100ipm and the acceleration ways reduced from 30 to 25 on all axis before the jog test. All motors are barely warm and the drives are also barely warm. I find it hard to believe it's over current. All Gecko drives current limit is 20 amps and is set to maximum. It will error at lower speed, at lower acceleration, moving any one or more axis, it is unusable.

Are there better options for wiring these drives? Are there better drive options out there. At this point I have an 8 year old brand new piece of junk, costing $12k. I could really use some expert advise as I'm to the point of depression as I can't really promote my gun case business with a goobered up cnc... Nice day all...
