    Ez Trak servo encoder repair

    I recently replaced the z axis servo on my Ez Trak. Since the brushes looked good, how would I go about cleaning or replace/repair the encoder so I would have a spare?

    Re: Ez Trak Z axis fault

    I replaced the z axis servo and everything works great. The brushes looked good so the fault was probably within the encoder. Thanks Mactec54 and Mbservice.

    EZ Trak X axis drift

    I have a 97 and 98 ez traks. The 98 is solid but the 97 will drift in the x axis about .003 an hour of use. What would be the likely suspect?

    Re: "Y" axis problems, need help

    My guess is a mechanical problem. Check for any movement in the y axis control wheel when powered up. Also let us know what you have found wrong.
  8. Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!

    I'm not sure what a 7 Pentium is but it sounds like a later version of the Pentium processor. To replace the motherboard, you need an OLD pc board. 486, 586, or the earliest Pentium processor. The...

    Re: ISA Half-Size CPU board for EZ Trak

    The 2000 mill has a "disk on a chip" so if you don't find a similar one with that feature, you will need to install a HD or a solid state drive into the drive slot.
  11. Re: Bridgeport EZ Trak CMOS error, replaced RTC, still broken!

    If the solder job on the board does not "look" good, it probably is not good. That timer chip has memory on it and it if does not work, the mill will be dead. I replaced the timer chip on my 1998...

    Re: Need some help with my ez trak

    If your problem is not exclusive to a single axis, then it is likely to be BMDC related. Clean the connectors and reseat the card. If that doesn't fix it, if you know someone close who has an ez...

    Re: Need some help with my ez trak

    No, not a home or limit switch but somewhere in the encoder circuit. The DAC overflow means the BMDC has called for a move and it was not made. It is somewhere from the BMDC to the servo in the axis...

    Look to see if you have a bad sensor in the axis with the problem.

    Re: Ez trak battery location on motherboard

    Your motherboard has a solder on ni cad battery. It looks like a axial cap and is probably in the lower right corner of the photo hidden by the cable.
