The following error message (with different numbers/axes) is received:

Axis drifted.jpg

The error code associated with this message is: 27102010

This error means the machine found the home switch in a much different location than it has previously.

This suggests that something in the system is loose.

Possible loose components for this problem are, in order of probability:

  • Pulley on ball screw shaft
  • Pulley on motor shaft (if it is a low power or otherwise unkeyed motor shaft)
  • Loose home switch or home switch bracket
  • Loose ball screw bearings
  • Loose ball nut

How to check directly for loose pulleys

If this error is preceded by the following error message:

The problem is NOT loose mechanics, and you should follow the following route: Axis lost pulses error message

Note that this error will only come up if the index pulse is enabled on that axis.
