New build with recycled parts on a ridiculous budget 120cm*60cm work area

Quick question my AM882's the power in is marked AC for both inputs which one is the + and which one the -?

As Neale has said. But not all AM882 are the same I think you have bought them from different sources so check all of them. I think it is the AM882H that can handle AC or DC and the AM882 is only DC. As usual could be wrong.

You right the AM882 are DC only they discontinued them now in favour of EM806 which I should have bought. Oh well think it'll be ok anyways ;)

Next time going for a stepper motor, encoder, driver combo all round. Expensive but really the only logical choice.

Morning, quick question.

My PSU is in an old PC case when I run power from mains to the PSU can I drill a hole in the pc case add a bolt and nut then use a round terminal to connect the earth from the mains to the pc case to create a ground?

Is this safe? I'm then going to bolt the PC case with the AM882's to the PSU's case so that's grounded and then I can connect the metal RF shielding from the CY cable to the am882's pc case and it's shielded.

does this all sound good?

Also how I understand it I do not ground the CY cable at both ends (In my case at the stepper driver end) is this correct?

Thanks

She's going to move today fingers crossed ;)
