    Yes Bloke, I have Randtronics.

    So that means no screw map, and I can change out the Dallas without a problem.

    Is it worth adding a few extra SRAMS ?
    I have no PC connection, only print out of programs, which drives me nuts as the printer triple spaces every line.... so i don't do that unless absolutely necessary

    Thanks again my friend !
    Rich

    Extra SRAM won't be seen by the control, so isn't worth fitting. The leadscrew and backlash compensation are entered on the dual axis DIP switches so that saves that problem. The only thing you'll need to enter is the travel lengths for the axes and where you want it to calibrate (which corner).

    Will the control ask me for length and Home position or do I need a special screeen/password?

    Thanks Bloke you have been incredibly helpful to a retired old man who has a Hurco strictly for enjoyment.
    Even though it was used, My wife gave it to me for a retirement present, 8 years ago to keep my mind active

    Rich,
    If you can print the program, You should also be able to connect it to a laptop and using Hyper Terminal download the .txt file for record keeping.
    In HT, create a new file call it Hurco (of course), than You will get prompted for the connection type, choose com1/2/3 whatever you have, do not bother with the phone#, press enter and it will ask you for the "port settings" enter the same settings you have on your machine control/communication, BPS, bits, parity, stop bits, flow control, hit enter and You are ready. Go to the toolbar and choose "transfer" than "Capture text" , and as You hit the "print " button on the Hurco, the text file will be downloaded to Your pc. Copy, paste, save, print, You can do whatever You want with it. ( I`m typing by memory, hopefully is correct, I will check tomorrow)
    Also I've looked into the screw map page, and in both my machines you get access from the Diagnostic page. Power to the servo has to be ON, go to diagn. page, press "Enter" "642" and "enter" again and the page appear ( if You have it ) , i was not aware of the different software versions available with different drives, on mine I have Yaskawa AC servo. I`ve learned something too.
    Remember the most important rule " don`t fix it if it ain`t broke"

    For the travel lengths, you'll need to set X 24", Y 14" & Z 5".
    Then set the calibrate directions (X left or right, Y forward or back).
    When done, type "enter" 999 "enter" and the control will re-boot. When it re-starts, it will have the total travels and calibrate position stored.

    Thanks Bloke. I went and installed new batteries in my board thanks to this thread. This is about ten years over due.

    BTW...
    The mystery AB transistors on the KM3p servo amp boards can be replaced with MJ10021 Darlingtons by ON semi. Make sure they all have the same manufacture date and or wafer lot so they match up.

    Talking Tweaking the limits.

    On my Uncles KM3 I was able to rotate the ball screws by hand and find the hard limits, then adjust the tabs for the the prox/roller switches. This allows you to use the most of your machine. - DO NOT SET THE LIMITS TO THE HARD LIMIT! You must allow some space for the machine to stop.

    Check both ends of travel. When done I had X24.7 Y13.77 Z5.16 - what you end up with will vary. One factor will be the Index position in the servo relative the ballscrew - How far will the machine have to back off the limit before it finds Index and calibrates "Home". This can be adjusted by moving the Servo pulley a few teeth relative the ballscrew. Don't know if Direct drive Axis can be adjusted (too much work anyway). Note that if you swap Home locations (Front vrs Rear, Left vrs Right) your adjustments go out the window.

First I have to use enter 999 enter to go to next screen then in manual mode when I tried to reset servo or calibrate the machine x axis motor oscillates making machine to vibrate and on text screen I get error " lead screw checksum map error . invalid data or errased, what would be the problem and what should I do . Your advice and help in the matter will be highly appreciated.

    what if I have lost all memory . this is because I am getting error message " leadscrew map checksum failed . Invalid data or erased. I think tlhis is memory loss problem . Is this true . lif so please help me and guide me as to what I should do . there are many problems coming suddenly in my km3p as it was in storage for almost an year without power.
