I am currently enrolled in a Technical College for Machine Tool Technology. I am a workstudy for my shop instructor, and one of my duties as such is to see if I can fix machines when they break, but this ones got me stumped.
It was working fine one afternoon, but the next day when we tried to home, the Y motor moved faster than normal for a couple inches, then the Y DAC overflow error came on the screen.
I read the thread about EZ-TRAK SX not reading the hard drives, and it was mentioned that it may be the BMDC board. We have another EZ trak that requires an external keyboard to press f1 on startup, but it works fine after that, and this one was opted to be the donor. After unplugging both machines, I removed the BMDC from the probematic one, and replaced it with the donor, it then homed the Y, but gave me the same problem with the X. After putting the original BMDC into the donor macine, it also overflowed in the Y. Now, both BMDC's are in the original machines, and the first machine overflows in the Y, while the donor is back to normal.
Any help on this would be greatly appreciated, and if you need more clarification, let me know.
Thanks, Dan
