Hi Sergio,
Thanks for the thought.
Since my MM, computer and control box sit in a drafty uninsulated shed, I guess conditions are ideal for corrosion of contacts.

Check out the videos on the PMDX site. They help a lot. I would follow 2.13 to 3.0 in the manual. You should have a jumper across the e-stop because the PMDX126 ships that way.

Thanks, David.

Hi David,
I have a single vacuum extraction point. Good thinking on isolating each suction cup. I'll see whether I can source one-way valves.

Sergio,
I'm guessing you are putting flanges on the top of the legs, vertical supports and cross supports and bolting them all to the beams?
A lot of holes to drill on the underside of 3.8m beams!
