Can someone tell me whether the three negative output terminals of 12 Volt DC outputs of the Suwell S-360-12 power supply have a common connection?

This is important for me to know, and I have not been able to find this informaton elsewhere.

You are building a 3D printer without a multimeter at hand? It comes handy several times during setup...

You could easily answer this questin with it.

Sure. I have a multimeter (two actually). Without an oscilloscope, I wasn't sure it would answer my question, though. They could be separate (float), and still measure no voltage between them.

Thanks. I did receive the answer elsewhere. The three sets of terminals are for convenience only. The positive set of three are interconnected, and likewise the negative.

Use your multimeter to measure the resistance between them, with the power off. You will find it is a small fraction of an ohm, because the -ve outputs of PSUs like that are always commoned. Similarly for the +ve outputs.
