Checking out a machine. Any tips?

Some pics of the beasty.

Hiwin rails and slides all round. 16mm ball screws.

Z axis has moving rails, which is good.

It's made partly from extrusions and partly from plate.

Gantry uprights are quite tall and might be a bit floppy but they are 20mm thick.

Everything feels nice and tight where it needs to be.

Bed is not shown, it's a slab of 15mm cast iron with an ali plate bolted onto that, which has been drilled and tapped in a grid.

Spindle feels smooth and vibration free.

Appears to be set up for spray mist. There's a line running to a valve mounted (or rather strapped on) on the front of the spindle which would take a liquid feed I assume. There's only an air line there at the moment.

It looks you have found a very nice cable machine with many good points

It certainly looks ok, not the biggest capacity, but if that becomes a problem, it wouldn't take much to extend the bed...

Came with laptop and mach3 2.0, collets and a few endmills too.

VFD is a Schnider ATV12 and stepper controllers are CWD556's. The motion controller is a UC100.

I've been checking out the machine some more. Mainly tramming today.

I found that it was out a little.

Adjusting the spindle mount to get it perpendicluar to x axis (left/right) is pretty easy, but is there a prefered method to adjust the other direction?

My tramming arm is 100mm long, so over 200mm I am seeing 0.2mm 'nod' forwards. I was thinking I just need some very thin shim stock under the bottom bolts of the spindle mount?
