    Password? Where do you have to give password? Ok, in my opinion you should check point 4. Ereased program or reload all system? Are UV machine coordinates on display changing?

    FX20 No Contact

    To sum up: 1. Problem with No wire alarm is not solved, you checked this switch with multimeter and it's ok? 2. I think, you should disconnect each connector (with no wire on rollers) and check continuity to table and to powerfeeder modules (UP and DOWN) , probably W should be to one of...

    Afaik NO WIRE is from switch near wire rollers on left side of machine. The other wire contact is on top upper head, then up power feeder. Down aspirator and lower power feeder. I'm not service but IMO you should check cables W E (contacts on the left rear side of control cabinet), one is...

    Mitsubishi EDM FX20-K (Year 2002), I need HELP

    1. Did the problem happened suddenly or it happened after system reloading or other changes? 2. What is the ratios of movement? 1mm Z moves equals 1mm V? 3. How do you know that it is moving, you see on absolute coordinates or you see it by eye, dial indicator? 4. When you move 10mm up and...

    upgrade from disc to usb on mits FX10

    Yes, but i don't know how to read them because they are CP/M floopies. Some guys send me their system files but pitch error is individual for each machine, they send floopies to guy who make images from them. You need HxC floopy emulator with SD card.

    upgrade from disc to usb on mits FX10

    The cheapest option (but only for program loading, not system) is gotek emulator from aliexpress (~40$). In my FX20 I have SFRM72-FU-DL, works great.

    FX10 wire breaking when run VG program

    Hi, I think it isn't software problem. Check wires going to bottom and top head. Test cut with different epack - pay attention to different Ip settings, How did you adjust Vg?

    Mits FX20K wrong axis direction

    You can access some hidden settings/menu. When you in settings menu there is maintenance user and maintenance maker, AFAIR you should press M and input in both.

    Mits FX20K wrong axis direction

    I have no idea, I have problem with system load on fx20 so i can't help but I have old photo from PIT ERR menu, maybe it could help. It's from FX20 97'. You can try to find some description about COMP S. and SPCDV in meldas manuals. I asked my friend to send pics of FX10K and I enclose them too.

    Mits FX20K wrong axis direction

    Do you load properly pitch/backlash error disk? Wrong scaling on all axis? You could try to measure how much is the deviation. Is it like 120mm over 100mm travel or 100.2 over 100mm travel. You have FX20K so do you have linear scales or encoder?
