    Re: M41 SPINDLE MALFUNCTION 1

    I found that when I open the machine, the axes go to the home point. So far everything is normal.
    when I turn the spindle by hand on my screen it shows revolutions per 8 for example 8 then 16 then 24 then 32 then 41 then 49 and this continues as I increase the revolutions by hand .
    Maybe this shows you where the problem is ?
