    dear All
    1- for seeing parameter on TNC 426 go to Edit mode ---select any program ---push MOD ---put 95148 then ENTER ---- for getting out just push END
    2-for adjust Back Lash try to correct value on MP710 as MP 710.0 X axis MP 710.1 Y axis MP 710.2 Z axis ....up to rest axis
    3-for HDD broken you need to have A- software 28047415 ( i can send you all soft you want ) ,..let me have your email , also you need same HDD as its easy to find in your local market this is easy procedure i send you step by step ,..just needs the machine parameter list or any back up you have ,[email protected] please send me any things you have ,..if you dont have i have same machine under my service i can prepare HDD to send you ,..its your Call
