Nearly there Greg!

The free version of Mach3 limits the number of steps - I wonder if that is why your file stopped running?

VA is definitely Volts X Amps, equivalent to Watts.

Eg. think of a 500 VA power supply giving 10 Amp @ 50 Volt

12VA consumed off a 120V circuit means only 0.1 Amp (Volts X Amps = VA)

Inrush 70VA is the figure I would design for. Also make sure your relay's contacts open wide (and fast) enough to handle...

If I understand this right, you are relying on a miniaturised 12VDC coil relay to open 120VAC contacts when you push an e-stop? I don't know if this is standard practice - I would check that relay...

Sorry Greg, I didn't look at the 12V stuff. Yes, 12VDC in that cable will be okay.

The leftmost two wires in my diagram need to be swapped. The very left wire is the common for all the pushbuttons, ie. ground. But, if you trace it up to the PMDX, it goes to the dedicated e-stop...

You must definitely NOT run the 120V inside the same cable as the signals. The 120V e-stop circuit sits in a cable all by itself, exactly for the reason that it will generate noise.

Nah, the sawdust shouldn't only be on one end of the table and the off-cuts should be joined together. :p

The holddown bearing runs near the edge of the angle iron - only a small part of the roller could get over the hole . . . that is only when you are at the limit of travel (when you hit the end-stops).

Nils, you would be surprised at how much grease there is on steel and how it affects paint adhesion. Clean steel rusts within 30 minutes. If you don't see rust on steel, then it isn't clean! :)

On the over-countersunk of the z-slide plate, you could use longer screws to reach the other side of the rectangular tube. Or even longer and fit nuts on the other side of the tube.

For the over-countersunk, a copper washer might do the trick, if you can find one. It should be soft enough to deform and fill the gap.

There seems to be multiple issue with the hold-down roller,...

You guys are far too exotic - we use aluminium for this. But you have to spell it right. :)
