Introduction

If you are having issues with your Denford machine not homing the likely cause is the homing limit switch for that axis.

If you request the machine to go home and the axis travels in the opposite direction the first thing to check is the limit switch is clean and free of dust. If it has anything lodged in the switch it can stick on.

If you have ensured that the switch is clean and the problem still exists then proceed to follow the steps below showing how to replace the limit switch with a new one.

    • Open the Door on the machine and then turn the machine off.

  1. Obtain a new limit switch. You can purchase them from the REA Store if required.
