Well, it lives! And after much trouble too. First, the servo would not stop going. No matter what I did with the configuration. I finally found out that the computer was trying to move the motor, but had the direction backwards. I did think of this and tried to reverse rotation within the drive configuration. But that didn’t have any effect. To make matters worse, the computer would leave the analog signal at 10 volts when it went into emergency stop. The fix was simple, but a bit mind boggling. I had to reverse the polarity of the signal. The software should have sufficed, but this is what it took.
Finally, the X axis homed. But that’s all it would do. It wouldn’t jog, or execute gcode. It took many days of banging my head against a wall till I finally gave Bob McManus a call at electromechtechservices.com After talking over a few things, we found out that the feed rate was at 0. The connection to the feed rate switch was unplugged. Hey man, stop laughing. I’m new to cnc. 😳🤣
Well, it moves, it zigs, one may even say it zags, and it can make a tool change. Let’s calibrate and make some chips. Right?! Well, no. 😥
Z axis limit switches are failing. Given the crappy wiring job at factory, Y is probably right behind it. Y belt is also shot. And the pulleys have seen better days. On top of that, this thing is messy inside. It needs to be properly cleaned out and lubricated before use. The Y motor needs to be pulled to replace the belt, and to cleanout underneath the motor. I already have the driver for the Y axis. I might as well just buy another motor and replace the Y servo as well.
