I might well change the display to current later on. At the moment I am still taking it easy with depth of cut and feed speeds till I get used to what I can get away with.
Jazz, I know what you mean about Ali. You can hear the change in the tone of the cutter when you get a change in the material. We also get it alot when cutting mild steel on the laser at work. The cut quality will be really good then it will go crap for a while when we hit a bit of crap steel. Sometimes it can be right down one edge of a plate. Makes the operators think the beam alignment has gone out.
Jonathan, the ribbon cable is around 2.5mts in length at the moment. This might get shortened a bit when I decide where I am going to mount the box.
