    Default Interact 1 MKII TNC 2500

    I have had one of these for several years for my home shop use. I had not run it in several months, maybe close to a year. I get a Gross Positioning Error Y C. I checked the motor cables, brushes, took the encoder apart and checked connections. Tried changing the voltage at parameter 1140. I decided to home Z and X and let Y warm up. In a few minutes I smell smoke and kill everything. A resistor is burned up and maybe the transformer on MT1-1 board. Probably repairable, but second time, different resistor. Another periodic problem is the KTK drive errors out if you try to run a high RPM, I have to step it up in the program. I am so sick of this stuff. Should I rip all the electrics off? I like the Heidenhain control and have a good programming system. The machine is extremely low hours and mechanically excellent.
    What to do????

    If you let the smoke out of the drive card, then you need to have it repaired or get a replacement

    the KTK drives are a pain I hear, but if it works mostly....

    the control itself is pretty sturdy, but the attached electronics sound like they are letting you down
