If anyone has a set of manuals for a SL-3H with Yasnac LX-1 controls. The maintenance and Operation in particuliar. Also the factory parameters on disc. I pulled a BoneHead move. While setting up the RS-232 on my machine I accidentally overwrote the parameters for the machine. I left the parameter switch on when I sent the first program out to the machine. Well that writes to the parameters. I have all the user parameters 6000-8000 ?? But what I get when I put in a Program number it says memory full and the control shuts off. Also the spindle control seems to be disabled. Any help would be greatly appreciated. Tim @ Precision Performance
