Thanks for the good information. There is an MV Jr on ebay right now with a non- functioning controller. I bought my Kasuga as a running machine, and as you suggested, there were few surprises. But eventual breakdowns forced the EMC conversion on me. Now it is a reliable & accurate machine, and I am very happy/productive with it. I checked out that photo again and noticed that the machine is positioned directly under a skylight. It looks as if you turned the problem of height clearance into a natural lighting "feature". Very elegant solution! Tom Tom ------------------------------------------------------------------------------ Come build with us!
