After much appreciated help from another member of this forum LHR did replace the controller and defective card. Very shortly after I tried to use the machine and got a message to put in the unlock code. The machine would not accept that. The people at LHR sent me a program that I had to load on the card and reset all the code in the machine. Now each time I use the machine I have to do that step. Honestly, I have not used the machine much. I am wary if it will complete any projects for me before it fails again. I have not even tried to market what I can do with the machine for fear that it won't work and I'll have a customer that would not use me again. When it does fail again watch this space and you will probably get a good deal on the machine.
An FYI, I have Ringneckbklues DC and use a dedicated circuit with a surge suppressor and I have run a ground wire from the DC metal to a cold water pipe since ANY amount of static will apparently fry the board.
I got this machine to embellish the furniture that I make. I have a fully furnished wood shop and I build custom pieces.
