    Fadal 88hs backlash table

    Hope someone can help me with my problem.
    On milling machine Fadal 88HS appeared alarm: No parameters or parameters corrupted. (I have no previous experience with that machine).
    I easily found a manual to fix the problem but after zeroing memory it's not possible to open backlash table. With inserting command BL there will appear an answer: you must enter the backlash table (see the BL command)
    Is there any other command besides "BL" to enter the backlash table ?

    If your not familiar with setting back lash just enter BL,1,9,9,9 (Sets X left, center right backlash to .0009. The type in BL,2,9,9,9 (Sets Y left, center, right blacklash to .009) then enter BL,3,9 (sets Z axis backlash to .0009
    We have had good luck with our Fadals milling mostly soft steel and aluminum up to 5 axis. We are always looking for spare parts If you have a broken down Fadal give a shout.

    Thanks, it helped!

    Now I have a next issue - while jogging the axes with wheel, the movement doesn't respond 1 to 1. What i mean if I try to move a random axle 0.01mm, first time it moves 0.02mm and next time 0.03mm ??!
    In the setup i have the mm mode ativated.

    Check your parameters to make sure you are using the correct ball screws. Is it a metric ballscrew or SAE ball screw. and check
