Cut Drifts In Axes

Scenario

Cuts are drifting in one or more axes. Depending on the version of the software, and the tasks being done, an error message may be received indicating loss of pulses or axis drift.

Problem

There are a few common causes for this problem:

Loose pulley or mechanics

Electrical interference/noise

Problem with NC file geometry

LC+/MP/Premium controllers only: Verify control cable

Solution

There are a few pieces of information necessary to determine the cause of this issue.

  • Does the drift continue in one direction, or does it bounce back and forth for a short distance?
  • After the drift happens, is the origin of the part exactly where it was before the problem occurred?

First: Test for encoder pulse issues

Next: Test for mechanical drift issues
