Other M2Nano-Style boards such as the B1/ M1, Moshi Board, and others may have a 6 pin power plug, instead of the 4 pin version 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 6 pin power connector.
6 Pin Variant
This type will typically have 24V, 5V, L, and Gnd connections. The voltage (24V) might come from the Laser Power Supply Unit (LPSU) or a separate power supply, while the L and Gnd come from the LPSU. These will vary, but see examples below:
|Laser Power Supply Unit||24V Power Supply Unit|
Identify the existing L and Gnd connections on the stock control board. The ground being utilized is commonly the one on the right, but check to make sure (especially if you have two Gnd terminals). Trace the wires coming from the 6 pin plug to the LPSU. Compare to your LPSU diagram and use a multimeter to test continuity for the respective wires.
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 6 pin connector may look like on the controller:
|Moshi (MS10105 Older)|
|Moshi (MS10105 V4.7)|
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. Disconnect the pins or cut the wires from the power plug connector, then insulate them with electrical tape or heat shrink to be extra safe.
