Mini Gerbil for 60w Laser cutter?

I searched contact informations on their homepage, but I didn’t found anything. Do you have some for me?

They have a forum that you can register and post on - I don’t have contact information for them. I did see this page in their hardware installation:

I looked again, the blue and green wires are TL and Ground on the M2Nano, but i dont know where to put it on the MiniGerbil. My power-supply dont have any LO Pins and the “4-wire plug” is only with 3 wires (LO is missing). Could this help in any form?
