Axis stops moving

When an axis on your CNC machine stops working correctly, the issue is either in the main control box or the physical axis that is having the issue. To narrow down the source of the issue, the steps below will switch the motor connections between a working axis and the issue axis.

(For this example, the non-working axis will be Y and the working axes will be X, Z, and A)

• Power the CNC machine on, jog the X-axis at all motor speeds, to ensure it is operating properly.
• Power the CNC machine off
• Swap/exchange the X & Y motor cables at the X and Y ports on the control box.

• 1. The X motor cable will now be plugged into the Y port and the Y motor cable will be in the X port.
  2. On the LCD Pendant or Ready2Control; the Y+/- buttons will now move the X-axis motor (Left/Right) and the X +/- buttons will now move the Y-axis motor (Away/Near).
• Power the system on
  1. Using the Y +/- buttons, jog the X-axis motor left and right for several minutes or until the axis stops working.
  2. Using the X +/- buttons, jog the Y-axis motor away and near for several minutes or until the axis stops working.

Results:

For this example, the non-working axis is Y and the working axis is X.

• If the issue stays with the Y-axis motor while connected to the X-axis port - the issue is in the physical Y-axis.
  1. Check the motor cable is connected to the motor
  2. Check that the coupler sets screws are tightened onto the threaded rod and the motor shaft
  3. Check the T-nut on the lead screw is tight
• If the issue moves to the X-axis motor while connected to the Y-axis port - the issue is in the main control box and is a driver card issue.
  1. The driver card will need to be replaced
     1. HD4/HD5 Single Axis Motor Driver Board 1360 (Does not include 4th Axis)
     2. HD3 & Older unit Driver Card
