Hi Todd, Yes, this one has the Balluff BRGE1-WSE10 encoder mounted behind the turret cover. It's an absolute 10 position encoder and as told in the other message, I'm just doubting this is the problem. I'm beginning to believe may be there's a CPU problem because I'm getting too many weird behaviours every week.
I would love to install LinuxCNC in this one but I would like to keep the original servo motors. I can replace the encoders in the motors easily, but I still have to find a proper driver to use with the motors. > Are you sure that the machine uses an encoder for the turret positioning? > The fact that it will work at some tool positions seems to sound more like > it has a series of switches, and that one of them isn't working.
