hello everyone,im still not further with my machine,i have done some tests with the osp 2200,the voltage an the cpu voltage are now in proper range.the binary tape stops at the last holes but the no1 control tape just want to stop stop at the last holes.
what i explore on the main switch board is that 2 leds dont work properly one light al the time and one newer,but when i place the memory switch in the up position then they work.but with the PC switch in up position-on then they dont work.i am 99% sure that a circuit board are bad.have anybody any idea???
i newer come to this conclusion without help from a friend from america and i thank him so much
Regard
i have to update this treath with my newest results
i find some used pcb boards in finland and buy the
memory module (16K)
mother board
3D Board
Switch board and pcb board behind the switch panel
After i plug in the new boards i first try the flickering method (that dont work with my original boards)and try to feed the memory with the control tape NO1
The tape dont stop at the last transport holes so i try bootstraping the machine and load the binary tape.everything work just fine to the binary tape.and then when i try to load the control tape NO1,the tape dont stop at the end and just runs trough,i try everything about 50 times but i ever get the same results.
i think that there could be a problem with the 1F2C pcb Board that controls the work of the tape reader.but if so,why the biary tape stop at the correct place and the other tapes not.i also receive the tapes of the new memory module.
have anybode an idea what could be the problem here?????
i would really appreciate any kind of answer.
Thanks guys
Ok guys i got finally this machine started:rainfro:
sorry mods for updating this thread again but i just want to help some people (if there are still someone like me that uses osp2200) who maybe have the same problems so i can help them,cause the machines are really rare but reliable and still good working after 30 years.
i manage to fix my problems but i had to change all of the pc boards in my osp 2200.
after that everything went good and now i have a fully funktional machine
so if anybody have a problem with a osp2200 i would really like to help them
dont hesitate to contact me at
Hello Friend
is me again with my old okuma )))))))))))
my machine is running but i have still problems to use all of his options and i can only use G0 G1 G2 G3 and one tool
i will write again my problems and what kind of work iv'e don't on the machine
It's a long time ago since we bought the machine unfortunately in a bad condition.first we did,we order original tapes from okuma switzerland a tried every option to load the binary,#1 and #2 tape but with no success,only the binary loadet but the two others never.
After that i made contact to a man in USA and first of all we checked the voltages and everything else that have to be check't on the machine and we came to a conclusion that the memory board is death 100%
Then i found a man in finland who had 2 of the okumas and he was willing to send the memory,mother,switch and #3 board to serbia for a really fair price.
the boards arrive'd and i imediatelly change my old boards with the new ones.
unfortunately no luck.
i ordered the other 8 bards from finland and so i changed all pc boards on my okuma
bootstrap good
binary tape good
control tape #1 good
control tape #2 good
i power up the machine and i saw the first time only zeros on the display ))))
after that i had to learn how to use and to program that machine and so i discover that some options are not working.
MDI don't work at all
tool offset also
after loading anykind of program to the memory its impossible to edit the program in the memory -error 79
lap programing also don't work,the machine don't shows any king of errors but shes not doing what she should.
Things that work
tool changer
changing spindel speeds,but only with help of a tape because the mdi dont respond
zero set
working with simple programs and one tool
ok that preatty much all
a big thing that i have to say is that it could be a hardware/software problem
i notice that the machine originaly only have 2 decimals (one nixie tube place on the pc board is empty) and by the original books you have to write programs with 2 decimals
i did that the first time i wrote a small program and run straight in the workpiece ))))))
fortunately nothing bad happend so i discovered that i have to write programs with 3 decimals.
i also notice that the direct tool offset buttoms are empty by default and maybe my new boards have the options to DTO,there are cables behind the control panel right behind the holes where the DTO buttoms should be.
I think that are enough informations for some specialist and i really hope that someone can help me to fix my problem,i would really appreciate that.
PS:here are some pictures
I will also upload some pictures of the tapes that i have
If you cannot input data from keypad then please check the jumper on Slot IF2 and make sure that K-B is jumpered. This will then enable the keypad. Make sure that the connection next to K-B( on the left ) is cut.
I have just noticed the Tapes on your Photos.
Make sure that you only load the correct Tapes for that machine.
Control Tape No.2 is your "Options" Tape. There will only be one of these and not very long. If you have load the incorrect Tapes then you would be lucky to have anything running correctly.
Again, please check that you load the Tapes for that Machine.
Thanks for your reply,i check almost everyday this thread for new reply's and anykind of help makes a smile on my face :rainfro:
i pulled out the if2 board and it looks like that K-B is jumpet and jumber next to K-B is cut,but i have also notice that there is no option to change this because this is so made by stock,you understand what i try to say,there are no jumpers like on new computer's,i will also make a few pictures later this day.
I also notice that (K) on the back side is connected to the other jumper but i think that this is normal because this are dubble side printed boards.
About the tapes, i think that there are loadet correctly,#2 tape is almsot 3 times shorter then #1 tape
but there are also big differences between my original tapes and and tapes i bougth with my new boards.i will also make some pictures to clear what im talking about
Is your Machine #1144?
If not then please use Original Tapes.
In fact I would use the Original Tapes first.
The Tapes that you bought with the other boards sound like they come from another machine. Don't use them.
Normally if Control Software Loads up ok and the computer runs, and there are still programming issues or machine is not running correctly, could mean that there is a problem with your tapes.
If there were any faults in Slot3~6 then machine would not run or in most cases you would not be able to load Control Software.
IF1 will affect the Panel and some Display functions. - could be a problem
IF2 will affect MDI Input and Tape Reader. - should be ok
IF3 is only Input / Output. - Possible problem but I think Unlikey as you have too many problems for this to be causing them all.
IF4 is ok as you can move axes around.
Are you running CMOS Memory( 16K ) or Core Memory( 2 x 8K )?
If CMOS( 16K ), has Slot 3C been changed to 3D and Modification to Motherboard been done?
Lots to check but we need to start form the beginning now to make sure all is correct.
First of all here are the pictures
right are the tapes i ordered from japan a few years ago and left are they i bought with the new boards
the other two pictures shows the jumpers on the board on front and backside on the IF2
i think this is clear now
ok now to your questions
i have a 16K memory board but im not exactly sure if it is CMOS or core memory but i have all pictures of my new boards and i will upload them later this day.
i also have to say that i changed everyone of my boards including the motherboard and the switch board so i dont think that i have to make some changes on the motherboard.
i also have the 3D board next of the memory board where you can select the sice of the memory board and this is also ok
ok its me again with some new pictures
i hope that this thread will also help other people who have problems with this machine
@sertec
here are all my pictures from my new boards
i have to notice that my old board are tan color so this are newer generation boards and i thank that everysingle one of them are in a good condition.
you told me that i should try to load my old tapes and today i think about that and i know that a few months ago nothing happend because the tapes dont stop on the last transport holes where it should stop if the tapes are properly loadet.
there is also a problem with the control tape #2 from my new boards because the tape was in such a bad condition that i had to fix the tape before i load it the first time in the memory
here are a few pictures
i fixed the whole tape and it run trough the tapereader and stop at the end,i think that is a clear sign that the tape is ok now,or maybe not???????
i really dont know i just want to run this machine
You are using Core Memory.
Can we go thru the steps again of how you have loaded the Control Tapes.
1. Start by using the switches as per instructions in manual
2. Then load binary Loader
3. Load Control Tape No. 1
4. Set Switches
5. Load Control Tape No.2
6. Power Off.
7. Power On.
can you set your zero offsets?
can you set tool offsets?
can you edit program?
can you select speeds by MDI( is your machine 12 or 24 speed )?
can you select Tools( what config is your machine( V6 + H4 etc )?
if you can do all of the following then i would say you have a runner.
can you set your zero offsets? ------Yes
can you set tool offsets? ----------- No
can you edit program? -------------- No
can you select speeds by MDI( is your machine 12 or 24 speed )?
------i have 12 speeds and changing speed with the MDI dont work but it changes speeds when i load a program
can you select Tools( what config is your machine( V6 + H4 etc )?
------tool changing works good,it also work when i load a program
but i cannot change tools with the MDI
