    Default Dead wizzard DT - transplant help

    Hi folks
    I have a a wizzard DT (Suregrave) which after many years of sterling service has rolled over with a failed logic board. Sadly Suregrave tell they have no more replacement logic boards.
    So since the rest of the unit is fine and built like battleship I was wondering about buying one of these chinese 3 axis logic boards to resurrect the beast.
    Problem is I think the Z stepper is a different rating from the X-Y does anybody know this is feasible or do just need to tow it out to sea and open the seacocks?

    Hi skelfie


    without knowing any details of your motors or stepper drivers
    I cannot be 100% sure if a chinese board can be made to work

    if the switches on the chinese board cannot give you the required current
    for the three motors ,
    you could possibly change the current sense resistors

    but look here first ---http://www.cnczone.com/forums/general_electronics_discussion/110986-how_i_fixed_my_chinese.html

    people have had mixed results with chinese boards

    I would prefere to use a breakout board and separate drivers

    John

    Thanks for that John, I'm going to try and find the spec of the stepper motors and take it from there

    cheers

    What was the outcome of your repair to the Wizzard. In the US we have a very good repair shop for Dahlgren/Suregrave.

    Well it's now six years later and I have finally got round to resurrecting the Old Wizzard DT, with cheap controllers off ebay.
    It's been so long I've lost my original Skelfie account so I just created a new account to save time.
    Had to build PC with a parallel port using bits from the spare part bin, but it's whizzing along nicely using LinuxCNC.
    Next job is build a case for all the gubbins so it doesn't look so much like an IED
    I've been using a Roland MPX-80 in the mean time, but as it's down to it's last couple of pins I decided to finally get the the old Frankenstein box back in action
    It nice having the old beast back in play
