    Deckel maho 80U (1999) millplus E252 error

    I have got this E252 alarm (tool in toolchangerarm).
    Its not possible to do a toolchange with M6, but if i do a M66 (manual change) and then a M6 directly after the ATC will work once.
    Any suggestions to fix this?
    I have tried the I/O recovery of toolchanger but too no help.

    Hi, this just says there is a tool in the tool gripper, depending on the version of machine, you may have a proximity switch on the gripper giving you an incorrect status. Check and see if there are any proximity switches on the tool changer monitoring the grippers and let me know.
    Cheers
