    CHNC II Fanuc 10TF - Alarm

    That was was the problem, there was a fuse blown on the power supply under the CRT/MDI Board that feeds 24vdc to the DIDO2 board. I really appreciate the help Vancbiker, like always I learned a lot, but without seeing all of the inputs all on at the same time on the diagnostics screen I don't...

    CHNC II Fanuc 10TF - Alarm

    Yes, not only X500.0-X500.7 but all of them all the way through X509.7 are on That doesn't seem quite right. All of the X500 and above go through the optical coupling and all of the Y500 and above do as well. I am going to check those as well. So I think I might might have found the...

    CHNC II Fanuc 10TF - Alarm

    To be real honest I am just starting to understand what I am looking at in the Ladder. I have out the book and have been studying it and it dawned on me not long before I read your post that all of the inputs are X0?? like the air switch in the previous post. So I have spent the last hour or...

    Just a couple more pictures it would only let me add 5 per post. Thanks Gary

    CHNC II Fanuc 10TF - Alarm

    I have attached a few different pictures and I will add a couple more in a different post. Should be a view of each point in the circuit except the air switch X008.5. As I mentioned before both the open collet and close collet relay are powered closed all of the time, but with the collet valve...

    CHNC II Fanuc 10TF - Alarm

    Well I have tried all of the things above with no luck. I replaced the cable between the DIDO2 board and CRT/MDI even though I didn't think it would help. Swapped out the CRT/MDI Board with no luck there either. I also disconnected the collet switch and tried activating it through the foot...

    CHNC II Fanuc 10TF - Alarm

    I have a PDF Fanuc 10-12 Maintenance Manual. I have looked through the 500 pages of it several times, but haven't really seen a lot I could make heads or tails out of. I will give it a closer look. It does have connection diagrams but not really wiring diagrams. I will look harder. Thanks Gary

    CHNC II Fanuc 10TF - Alarm

    It is pretty difficult to actually check across the switch since it is a membrane switch there isn't much to get at with a meter. What I can do is disconnect all four of the ribbon cables highlighted on the attached drawing between the membrane and the DIDO2 Board and nothing changes, so I have...

    CHNC II Fanuc 10TF - Alarm

    Thanks, I understand what you are looking at now, and yes, the switch is on the 0 volt Buss or the ground side. So with that said, I will disconnect the ribbon cables from the DIDO2 board to isolate them and make sure there are no problems there. From the DIDO2 board there is another ribbon...

    CHNC II Fanuc 10TF - Alarm

    Thanks I will check that, and I did see replacing and setting the pressure switch in the maintenance manual. I do know the the collet closed pressure switch works, because when I disconnect the collet valve solenoids and close the collet by jumpering, the collet closed pressure switch activates...

    CHNC II Fanuc 10TF - Alarm

    Here is a screenshot everything I have is to big to attach the PDF. I am not quite sure what you are looking for on the drawing or it is shown on this sheet, but here is what I have and I appreciate you taking a look. Thanks Gary

    CHNC II Fanuc 10TF - Alarm

    Attached is a diagram of the switch circuit. Also attached is a routing diagram for the machine. I have pretty good diagrams of the Hardinge boards, but they just show up to the Fanuc Boards so you sort of have to guess what is happening in there. The MEM01 Board is the membrane control panel...

    CHNC II Fanuc 10TF - Alarm

    Thanks and that is a good point, according to the diagram the switches are normally open, and when I view it in the ladder it also shows that they are normally open, although both the closed collet and open collet both show active (closed) which is seems to be the problem. As I said before I...

    CHNC II Fanuc 10TF - Alarm

    Only one set on this machine, and it is under the door, but I have completely disconnected them and it doesn't change anything. I have also checked all of the other points I could find such as the foot switch inputs and robot inputs. Thanks Gary

    CHNC II Fanuc 10TF - Alarm

    Hello Everyone, I am getting a Bad Collet Switch Alarm on an old CHNC II with a Fanuc 10TF control. What actually causes the alarm is that both the open collet and close collet signals are engaged at the same time. I have determined that it is not the switch. I can completely unhook the...

    titanium rifle action?

    By your standards bow hunting is irresponsible also because far more deer are wounded and suffer each rear from poorly placed bow shots at 10 yards than ever will be by people equipped to hunt at extended ranges. I am going to leave the conversation with that because the fellow who started...

    titanium rifle action?

    I have always understood that it was illegal to deface U.S. currency... shooting elk at a 1000 yards... not so much. Gary

    Threading rifle barrel cross feed vs compound cf?

    I am sure there are all kinds of arguments both for and against but I find it much faster to thread using the cross slide as opposed to setting the compound at 29.5 degrees and doing it that way. I prefer to turn my thread tool upside down and thread with the lathe in reverse moving away from...
