I think this may be the video you're thinking of...

Yes, thats the one.

I have tried this but couldn't get all the black stain off the melamine. I tried ink, watered down ink, acrylic paint and water based paint, all left a grey/light black on the white.

That's a shame, seemed like it could be a good method. I wonder if maybe there are different types/grades of melamine?

With respect to the images yes there's a lot of stopping and starting, from memory it was around 45,000 lines of code. I wouldn't be too concerned about the ball screw, that should be alright. My main worry would be with the connection between pulleys and ballscrew with respect to how well they are mounted onto shaft. If you have read my thread you would know I had a few problems with the pulleys coming loose on shaft and chewing the shaft up. I was always checking that the set screws are tight. Now its been a while with no loosening I can be pretty certain it should stay that way.

I haven't read your full thread, I will have a look. I too have had issues with with couplings coming loose.....when mine came loose the spindle dropped and almost set fire to my garage! (To be fair it was my fault for not keeping an eye on the machine while running)

That's a great video. With regard to getting stain off melamine, maybe before you start you could paint it with a thin coat of PVA, cut it, stain it, then the PVA + stain should wash off with water leaving the melamine clean.

Interesting idea eddy. The other example shown on Jason dories site is to cover the board in self adhesive vinyl, cut, spray paint, remove the vinyl. Seemed to work quite well.
