    Mitsubishi Meldas 65SM E51 error after restore from internal backup

    Post a picture of the "cassette". If it is a SRAM type PCMCIA card it will have an internal battery or possibly super cap that retains the card memory. If a battery type, a dead battery in the card will corrupt data. If a super cap type, the cap is charged by the card being inserted into the...

    Yuken Hydraulic Valves on Nakamura

    Not specific to Yuken valves, but I have seen several instances where sticky valves were a result of coolant contamination of the hydraulic oil creating a sticky residue that took some warming up to get things to move. just changing oil sometimes helped Other times required disassembly of the...

    Leadwell MCV1300 Fanuc OM Tool Changer Issues

    I’ve not worked in your model leadwell so….. Sometimes the limit sensors will be on the cylinder that moves the carousel rather than on the slide.

    Fanuc 0-Tc RS232 location

    Connectors M5 and M74 on the memory board are the RS232 ports. If your machine has a cable connected to either, trace it and see if it has a D-sub connector on it.

    External M Code Mori NL2000

    Is the coil voltage on your pump relay 120VAC? Does it have any auxiliary contacts?

    Easily grind on a CNC using electroplated wheels

    I’ve seen DavidScotts coolant filtering system and the products he was cutting. If I needed advice on how to best deal with abrasive or tiny particle machining waste in coolant, he would get my first call.

    External M Code Mori NL2000

    With the images I can help design a circuit for you to run a coolant pump. Before I do that I need to know how the M codes behave. When you execute M441, the relay KAM1 should turn on and the control should hang. Then when you momentarily place a jumper across terminals 3 and 4 does the relay...

    External M Code Mori NL2000

    MFIN will be an X address in you electrical diagram. When you find it post a picture of the page.

    External M Code Mori NL2000

    That’s why I posted previously to look through the ladder documentation for a keeprelay or Data address to see if your ladder has options on how extra M codes behave. Even if there isn’t, it’s not hard to make a circuit with a timer relay to generate MFIN. Mori folks writing the ladder...

    MORI SEIKI NL2500 Oil Cooler Alarm (M7549)

    I’ve seen several oil chillers lose Freon due to tiny leaks or cracks in the copper tubing. One cannot assume it’s ok because it’s a “closed system”. If cleaning the condenser doesn’t help then you really should get someone to do a complete check of the unit.

    External M Code Mori NL2000

    I have done similar when retrofitting a probe to machines that did not have logic specific to a probe interface. Many builders include logic for M codes for clamp/unclamp a 4th axis that in many cases I have been able pirate those for a probe since machine was not equipped with the 4th. This...

    External M Code Mori NL2000

    Won’t quite work that way in most cases. The MFIN signal should just be a momentary pulse. If it is continuously held on then any subsequent M code that is executed that uses an external MFIN will be seen to be “finished” immediately. Depending on what that subsequent M code’s function is the...

    External M Code Mori NL2000

    Have a look through your ladder documentation. Some Mori models used a keeprelay to determine an MFIN signal was needed or not.

    Nakamura w/18i /Block Skip

    Most commonly used to drive a Y output to turn on an indicator light at the switch. Best way to verify the function is active. Some builders just use the switch itself to turn on an indicator but that creates the situation where in the event of a failed contact in the switch or a broken...

    Mikron touch probe not agreeing with manual bore pickup

    .0002/12” or better was my target for realigning a crashed machine. Not always achievable depending on the crash and how far the machine owner wanted me to go.

    Nakamura w/18i /Block Skip

    @dandrummerman21: On Fanuc, F addresses are signals from the CNC to the PMC. G addresses are signals from the PMC to the CNC.

    Nakamura w/18i /Block Skip

    Dandrummer is pointing you the right direction. How block skip is activated/de-activated is completely determined by the machine builder’s ladder logic. Could be as simple as a panel toggle switch but can be done by M code or as a signal from an external device. Keep relay settings could also...

    Mikron touch probe not agreeing with manual bore pickup

    I guess we must be misunderstanding each other….. The OPs issue is because his spindle center line is not parallel to the Z axis. It appears that some misguided attempt to “align” the machine led someone to adjust the table to be perpendicular to the spindle centerline rather than realign...

    Mikron touch probe not agreeing with manual bore pickup

    Why would one want do do that????

    Mikron touch probe not agreeing with manual bore pickup

    When the machine was built, the spindle and Z were probably parallel to each other and perpendicular to the table, X, and Y. Now the OP reports the spindle is still perpendicular to the table yet the gage length error suggests that Z is no longer perpendicular to X and Y. Unless some...
