I have been thinking of adding a plate marker of some kind, any ideas whats nice? A camera may be useful for the zero setting due to table width.
Sorry, forgot about this, here is a nice way of doing markings on the cheap:
And a camera in a plasma environment will not last long, or if isolated properly needs constant cleaning.
Use a small cross laser, cheap and effective.

Tommy, have you found any replacement for the elmo 5/200 dc drives in the esabs?
There is a problem in one of my drives and is causes the fuse for the dc motor supply to blow up at the panel. On inspection there was a blown cap. I replaced all 3 caps but no joy.
On the plus side this is the first problem with the machine since proper completion of the retrofit. It has been brilliant!

One of the gantry ones, I have ordered a second hand one on ebay, but it will but be here for quite some time.
It would be good to know an off the shelf new replacement unit. If i find one suitable i will post it here for reference.

Ok, move the one from X to the gantry, and put the new/used one on X.
That way you have the same thing on both sides of the gantry.
Although that might not be needed with a used one if it is the same.

Check for a failed short device in the H-bridge.
