Great Build! If I may offer one comment that could possibly be an improvement: From this photo angle it looks like cut-debris (hot sparks, gasses, slag, etc) could fall onto your electronics - I would highly recommend keeping electronics on a plasma off the frame instead to keep them safe. Plasma cutting is a relatively dirty and violent process - which would also destroy sensitive electronics exposed directly to it. If it has to be mounted there, a waterproof enclosure around it would be a good idea.
