This is a plasmatable i built several years back, it worked damn good :)

It had an automatic torch height system based on tip voltage and a double z axis for measuring the tip height.

It was fast to 25000mm/m maybe faster if the controller software had allowed it.

Heres a shot of the linear trucks built using ball-bearings worked well but i wouldnt redo it today.

Temporarly hooked up and ready to cut, missing the torch tho.

Mounted a pen and let it print a drawing, looked cool but the tip wore out.

And the final pic its a tub i made, this is placed under the table and fills with water to bind all that nasty dust.

I made alot of reinforements to this table other than that you see in these pics unfortunatly i have no pictures of that but there was alot. If your thinking of building something like this make it sturdy, there might not be any mill cutter forces at work but keeping a somewhat constant speed and cutting into a corner then theres some serious weights that needs to start and stop at once.

Lets see do we have any movies in the archive well heres one, no thc or touch of in this movie just a constant height and 10mm steel plate.

First bits are in.  

Started on the gantry, made some last minute changes. After its built i dont have any good way of machining it if i need to so im trying to get all mounting holes etc made before it gets welded togheter.   ...

Tacked up the rest of the frame, when this is fully welded and filled with sand i will start working on the gantry. ...

Old energy chain im hoping to reuse in this project for x and y axis. All cabel will run in the same chain hope i dont get any trouble with interferance altough thhis is begging for it.      ...
