Here are some photos of the machine, vfd, computer ect...
I did an air test run this morning after I used 3n1 oil on the rails and moved the gantry back and forth several times. Why 3n1? That is what I had on hand and I did not want to just squirt grease in there not knowing about viscosities and such. Then I manually ran the gantry back and forth switching from regular speed to high speed and had no issues. Then I did an approximate 15 minute air cut. That went without issue as well.
I do have concerns about EMI and the computer. I shot a video of this as well. It only has the static when the VFD is running. I am fairly certain that they are on different circuits but will have to pull the panel to inspect further. When I run the VFD, the monitor goes black then comes back on with the static. When I shut off the VFD, the monitor clears up.
mactec, When I dropped the motors with the gear attached to the motor shaft and tried to slide the gantry, there was resistance. More on the right side than the left. After the 3n1 oil, it moves sooo much easier. My thought is that the resistance is due to dry bearings, that the right side would bind and cause the stuttering(?). Don't really know just an assumption.
