Installing a 2 Pin Power Connector

Some M2Nano boards and others, like the HT-XEON / HT-MASTER, may have a 2 pin power plug instead of the typical 4 pin setup that is covered as part of the LaserBoard Installation Guide for the M2Nano.  You should be able to follow that guide for everything else besides the 2 pin power connector.

2 Pin Variant

This type will typically have TL / LO and Gnd connections which will need to be identified on the stock control board. Trace the wires coming from the board to the Laser Power Supply. Compare to your LPSU diagram and use a multimeter to test continuity for the respective wires. Also, refer to our high level LPSU Connection Guide.

Prior to connecting to the LaserBoard, you can also test this by disconnecting the L and Gnd wires with the machine off. With the laser machine on, carefully touch these wires together and the laser should fire. This replicates how the board “talks to” the LPSU, but removes the board from the equation. Be sure to turn the machine back off before proceeding with the controller swap out. Yours may vary, but below are a few examples of what the 2 pin connector may look like on the controller:

Board Examples
M2Nano m2Nano 2 Pin Variant
HT-XEON (Various)

Connect L to the Laser Fire and Gnd to Laser Gnd on the LaserBoard. Cut and strip the wires to insert into the respective screw terminals. The board does not require the 24V nor the 5V wires to be connected. The 4 pin connector is not used and can be disconnected.

Additional Checks

For machines larger than the standard 300 x 200mm work area, review our Larger Laser Machine Installation Guide for the necessary configuration changes.

If your machine has inductive / proximity sensors, they will need to be wired in differently. Refer to the Proximity Sensors section in this document for more information: Installing Endstops / Limit Switches.
