    On my OKK you have to turn the power disconnect counter clockwise to the reset position to open the doors. This is a momentary spring loaded position. As others have mentioned above.

    Personally I would add torch probing rather than creating a work around to a problem. I built a probing setup long before I built a THC as its a simple setup. Mount your torch on a linear rail that...

    I am probably grasping at straws here but it is possible these alarms are some remnants of before I replaced the main board? Meaning maybe I need to do the whole "reset delete" (I think that is the...

    I am far from an expert but I have gotten out of similar situations by taking a very heavy finish cut and by playing around with conventional vs climb milling. Is if possible to make a "hoop" to...

    I found a little bit of information on the controller. Supposedly it was the first 32 bit CNC processor. It was produced from 86-94 and from what I can tell it is the same as the m500 except the m500...

    The speed of rotation is constant and the distant moved is constant but the time spent on return is less therefor the velocity must be higher.

    Mitsubishi Meldas M300 Questions

    I've never used a Meldas M300 control. What is it comparable to in a Fanuc? Can it run 3 axis simultaneous, threadmill, helical interpolate? I assume they can drip feed with an rs323?? Also what are...

    There is definitely something off going on here. When I boot up in IL mode it sometimes says 910 and other times 999 122 (sometimes also 132 and some others) and 911 which is high byte. But if I keep...

    I believe I did this and there was just a flashing light on the main board. I will try it again as well as hit 5 in IL mode and see if the 910 alarm is there. I'll do all this later today and...

    That is what I did. When you boot in IL mode you select 6 for RAM test and then hit start and then go around to the back of the machine and check the LEDs on the main boards. What I was saying before...

    OK, I have uploaded 3 pics.

    (1) a pic of the main board number 1 with all the cards mounted and you can see the I/O's below. All ram IC's are hidden behind the cards

    I just swapped the main boards around and despite their location the one that is in the one position always has a ram error, low byte #2. So there obviously is nothing wrong with either of the main...

    OK, I may or may not be getting somewhere. None of the PRDY relays are being triggered to close, so the problem must be on the Fanuc side of things. I saw in some previous postings that a 900 series...

    Everything from the spindle and servo drives goes back through 10PL,16PL,and 25PL which run to and connect below the I/O boards. I believe some then run into the I/Os and some run to more plugs and...

    64 goes to 16PL-5 which I traced back to the I/O and up to a hybrid IC on the I/O board (I assume this is probably a solid state relay). So while the initial signal my be issued by the main board it...
