Quick update......

Just a quick video of the Plasma table going through the motions. I still haven't sorted out the torch height controller yet as I bury the tip after about 2" of cut and stuff it up. I have so far burnt out 6 tips and 3 shields trying to get it to work properly. It's an expensive test cut. I will try the test with the plate on a slope to give myself a bit more time to hit the reset button on Mach so i don't bury the tip as quickly and to see if the height controller is following the contours.

I'll post some pics soon.

It's undergone a few design changes since the first one but I think I will settle on this one as it's pretty smooth and I will probably change out the X axis timing belt with a chain like the Y axis just to keep everything the same. You can hear the timing belt riding along the edge of the toothed pulley so it's not tracking really well. A bit of dry lube will fix that though.
Rich.
