Hi, I own a Techno HDS CNC router with an OSAI controller. The problem I am facing with the machine is that it constantly gives an error, which is (Y axis servo error) EE0011. The error occurs while the machine is running, idle, or moving the gantry.

Many times I try to restart the machine, check the cables on the y axis of both drives for loose connections, unplug the cables, blow the connectors with compressed air, and re-plug. but the error still occurs.

The second issue is that the x-axis motor makes noise or vibrates while at idle; the noise is not very loud but it is noticeable.

Please advise on what else we should look at on the machine to troubleshoot the problem.

Thank You
