This is what I bought. I didn’t want to buy it, but my brake isn’t big enough to make it.
And the light I built. I’ve had these 20w LEDs around for a while, so I mounted then up with my old 500mm makerslide.
I got my router speed controller mounted. It worked great in 500x500 configuration. I added a heatsink to the back of it since it won’t have much airflow the way it is mounted.
