    I have a Meldas 50 but much is the same for the 60 series. You need to reload your parameters from a backup copy. If you look at the alarm in the Diag screen there may be some additional...

    I would scope all the power supplies. Some Fanuc models power the control from an external 24V supply and the internal module is a DC-DC conversion circuit to create the other voltages needed. ...

    Locking out feed or spindle override control is determined by the machine builders ladder, not Mitsu. Most builders implement that as an M-code, but having it be a setting switch or softkey is just...

    I've only ever used lightly crowned rollers. Some jobs, we would put little "brush guards" mounted to the support arms to prevent chips getting caught between part and roller. That helped with part...

    Having multiple power supplies is so common as to be universal in CNC machines. The Fanuc CNC power supply is usually only used to power the control itself and sometimes input devices (limit...

    The engraving macro I have does let one scale the character height, but requires the control to have G51 scaling option. It was specific to some aerospace applications for transferring 8 or 9 digit...

    I dug up a copy of the 0i-B connection manual and found that the CRT can be powered from the CNC or an external power supply at the machine builders choice. Do you know which way your machine is set...

    With many controls, rigid tapping with the main spindle of a lathe has been around for over 25 years. Whether or not the ability is spec'd and implemented though is at the machine builders choice.

    Since G47 is a Haas specific function, your thought that it is a Haas issue is correct.

    There are many engraving macros around for Fanuc where the number to be engraved can be stored in a...

    That thought never occurred to me. It is possible that new boards/boot firmware could have some kind of password or even hardware "protection".

    If any here did, they probably threw up some.

    Discussion of a homeshop "CNC" would be much better taken to CNC zone forum. We hope to keep the bar a bit higher here.

    I've not seen this, but it sounds deeper than a failed FROM or SRAM module. There must be a boot load firmware that runs when the control is started normally or in maintenance mode. I'm guessing,...

    The 300 series control could do at least 5 axis if configured with the correct boards and firmware. Your firmware may (and probably does) have 4th support. It will not be active though. There are...
