    Thumbs up Maho Philips 432 answers

    Hello everyone ,

    I am the proud owner of a Maho mh 600 e from 1986 that I use daily in my shop. I am starting this post for those who need info or have questions on this subject

    thanks for your initiative. do you use any preprocessor and postprocessor for your maho? and how did you get it?

    Hello , I use EdgeCam. You can get the postprocessor online , or you can build your own post if you have a bit of patience and are familiar with the software and g code. I know GibsCam has a postprocessor for Maho machines but i never used it.

    thanks for you information. actually, The factory that I work with is using solidcam, and sadly, I do not have the sufficient experience in g-code to make a post.
    another question please, we have a big problem in running the DNC of our maho (it is maho 700, but I think that the changes are minor between it and maho 600). may you tell me how do you prepare your machine to run the programs in DNC mode?

    thanks

    Hy there are two ways to go about DNC transfer , one is BTR and the other is the normal transfer mode.

    Old Maho machines use BTR mode option from the menu screen to transfer large programs from PC that are to big to be stored in memory, Basically the controller loads and executes a couple of program lines and in the mean time deletes the executed lines and loads others. It works fine, I executed programs as large as 30 000 lines with it. I believe the standard memory size on this machines can permit you to store a program about 4000 to 6000 lines of code. So if you have a smaller program that you need to repeat you can use the normal transfer mode because using BTR mode it's time consuming and requires you to restart the procedure every time you want to execute a program.
    There are a couple of steps before you start to transfer :
    1 make sure your RS232 cable is configured properly
    2 the software that you use to transfer the program to the machine has all the transfer parameters set correctly ,like baud rate , stop bits etc. I recommend you Cimco Edit software for transfer since it also has the ability so generate programs for Maho machine from shapes you draw , great program
    3 now for the code itself there may be some modification you need to do , like in my case the program will not transfer correctly if it starts with : % PM but it will only with %PM
    It should look something like that :
    %PM
    N9001
    N1 G18 T1 M6 or M67 if you don't have a tool changer

    I must mention that to use BTR mode first you must alter a constant from the machine constants. In my case is the BTR macro size constant. You must decrease it's value to about 40 or 90 kb . Normally the value of the constant is too big. Here is the tricky part : if you make the value to small every time you transfer a program it will execute a couple of lines than it will stop the machine in the cut to load new lines. If you make it to big it will overflow the memory and stop the transfer , so be sure to practice a bit before starting to work.

    Regards

    thank you very much for the detailed information . Actually we was trying so much with the maho to operate DNC mode, but without any sucess, so let me please ask about some details part by part.

    1)regarding the machine itself, there is parameter 770 that says : DIO/DNC selection (0-5)
    it has values from 0 to 5 . what should this paramter be for activating DNC mode? are there other parameters that needs to be adjusted specially for DNC mode?
    2) after setting the parameters, what I need to press on the machine keyboard to make it waiting the data from my pc?

    thank you very much for you help

    I am away from the shop for 2 weeks so I can't tell you exactly the value for that parameter. I used only the factory settings for the parameters. The only time you need to change the parameters is after the machine has not been turned on for a long time and the parameters memory has been lost.

    Ok so if you want to transfer from the pc to the machine do this : press the MANUAL KEY than press the Prog Mem key then press F5 , You should see a list of programs stored in memory , Now type the number of the program you want to transfer from the pc . it should be a number above 9000 . After you have typed the number pres the Enter key once , now press the Data In out key an finally press F2 for input

    thank you for your answer. but why its number must be greater than 9000? we tried to transfer programs in memory (not DNC) and they were numbered 1, 2,3 etc..
    Does this mean, that the program that has number greater than 9000, will be considered a DNC program, not a normal program on machine memory?

    Can u send me a copy of the program you tried to transfer?
    The reason you use a number greater than 9000 is because of a machine constant , I don't know the exact number. This means that all the programs with a number greater than 9000 are interpreted asa external programs DNC , and all others below 9000 are the programs u make directly on the controller _internal programs.

    regards

    hello
    sorry for my delayed answer. actually I wanted to try what you told me with the machine first before telling you what happened.
    actually, I found the parameter that accept program number to be >9000 or <9000 , and the result in both cases, is either that the program that I send to be stored in memory normally (not DNC), or I get an error that program number needs be greater than 9000 (this happens when I send program with number 1,2,3 etc..., while the parameter forces the machine to accept programs with number >9000). thi is the test code that I tried:
    Code:
                       %PM5
    N5
    N1 G90

    also , regarding the instructions to work on DNC mode, you told me :
    "Ok so if you want to transfer from the pc to the machine do this : press the MANUAL KEY than press the Prog Mem key then press F5 , You should see a list of programs stored in memory , Now type the number of the program you want to transfer from the pc . it should be a number above 9000 . After you have typed the number pres the Enter key once , now press the Data In out key an finally press F2 for input"

    All of this is ok , and it works, but it to store programs in memory, it did not go into DNC mode.

    any suggestions ?

    Hy ,
    I see you use G17 meaning XY plane to program , are you using the horizontal spindle or you have changed the axis from the machine parameters? I ask you because normally on Maho machines you use G18 XZ plane for the vertical spindle. The program you sent me will crash the part or machine.

    To get into DNC mode you must pres Manual key, then Menu key , then the corresponding number key for Search ,I believe it's 2 or 3 depending on your machine , and finally the soft key F3 under BTR MODE ON. To verify you;ve entered BTR mode just pres Prog MEM key and you will not be able to see the programs list like before. Now there is the matter of adjusting the size of the machine constant called BTR MACRO SIZE, because by default it's too big. As I told you before if is left too big it will transfer program lines until the memory will overflow and stop the program completely, if it's left too little it will execute a couple of lines then stop the feed of the machine and transfer some more lines and so on.
    To exit BTR mode do the same steps again , or just turn off the machine and it will go back to normal mode.

    Regards

    I did not wrote this G-code, I took it from another post just for testing purposes.
    I press as you told me Manual key, then Menu key, then I press 1 (to choose "block search") ,and then I found the soft key F3 does not have any function inside block search option. there is nothing exist in that page to activate the BTR. I do not know why.

    thanks

    Hello,

    It is possible that your machine is not equipped with the module for BTR, In this case you should limit your programs to about 5000 to 6000 lines or just divide a larger program into sections. I've done this in the past but it is annoying. Send me your machine's software version and exact model and year of make , I will look into it.

    Regards

    Previously only used Siemens 840D controler.
    Now I bought an Maho Graziano 300 C-type lathe with Philips 432 controller. The machine program storage is empty. I want to create a new program, but will not allow it because the Soft-Key Lock and I do not know how can I Unlock. The Soft-Key does not work. The instruction manual says that there is an external key. When I turn the key on the keyboard it will not work.

    Manual:
    "Es ist zu sehen, dass die Soft-Taste LOCK angezeigt ist.
    Mit einem externen Schalter kann jedes Teileprogramm in Speicher gesperrt werden (damit es nicht editieren werden kann) und die Sperre der aufgehoben werden. Zusatzlich zu einem externen Schalter kann eine Maschinenkonstante so eingestellt werden, dass ein Teileprogramm mit einer Soft-Taste gesperrt oder freigegeben werden kann (LOCK oder UNLOCK) siehe "Interfacing and Installácion Manual".
    Ein Teileprograram kann folgendermassen gesperrt werden:
    - Teile prograramm nummer mit den Zeilenwahltasten wahlen
    - Soft-Taste >LOCK< drücken."

    Thanks for the help!

    Nice thread! Some good information here.
    Can you explain how you setup the connection between your pc and the maho?
    I'm trying to transfer programs (and later try to use the BTR function) from PC to Maho, but after 8 lines of code the transfer stops and an error "Data interupted" pops up.
    Transferring data from Maho to PC goes fine though.
    Can you post your machine constants N770, 771, 772, 773, 774, 775 and 776? And what sort of serial cable and pc program do you use?
    I tried hyperterminal, proezdnc and TNCremo but no luck so far :-(.

    Thanks,
