C10-board output Trouble

[Kencor1]

I have a C-10 BOB, my problem is that when mach is running my spindle relay output #1 works great On-Off no problem. However when I shut down Mach the BOB energizes the output #1 to 5V and the spindle relay turns on the spindle. As soon as I boot mach again it shut it off. This happens even though the e-stop is pressed. Does anyone have any ideas what is wrong? or is something wrong with the c-10 board? I have included a photo of my wiring.

Thanks

Hi i think this may be your problem

A relay has 3 contacts

1 common
2 NO = Normally Open
3 NC = Normally closed

I think you are using the normally closed terminal

The normally part refers to when the power is off

So when you leave Mach3 the spindle is energised

Thanks for the reply, but the BOB is outputting 0V when Mach is loaded but when Mach is shut down the BOB output puts out 5V. Why would the C-10 switch on the output?

Thanks

Explain how you have the RELAY wired that actually switches the motor and specifically what terminals you are using on the relay.

All safety circuits should be designed that they automatically become safe on loss of power/software control.

On all three of my machines, I have had to add additional switches to prevent just this sort of thing.
On my lathe, when I start Mach, hit reset, the spindle starts then by itself.
I have to physically start and stop the spindle on screen before I actually turn on the spindle switch before it operates correctly. It is using a DC motor.

My mill works as it should. If I turn it off though and get ready to shut down the computer as well, it will start up before the computer is completely shut down. I first turn ff power to spindle before shut down. Also a DC motor.

My router runs off a large relay. It will act just like the mill. If I shut the computer down with the PS to motors and BOB still powered, it will also start the spindle.

Just odd quirks I have learned to work around so far.
I intend to get the Charge Pump boards though and install those.
Also working on my second mill box now and want to do it right as well, so it will have a charge pump circuit from the start.

Then you are a stupid fool who one day will regret that you were/are so blasé about machine safety

I posted this because I am interested in a solution as well. I reported what my C10 boards are doing and why I use additional safety switches that completely override Mach 3. The behavior I explained doesn't happen when I use these switches.
If you have some additional constructive criticism to add to the thread, then be my guest. If you would like to continue wasting your time on putting a label on me, then please use the PM. At least then I will be the only one that needs to ignore you.

If I gave the impression that I was happy about it, then you read it wrong. I'll work on my splainin skills.

Lee i am sorry if i offended you, but maybe you need to put as much effort into fixing your problems as you do berating me for pointing out the error of your ways.

I asked the OP to post his wiring diagram in the hope that i or someone else would spot the problem.

I would say that is being helpful.

You did the complete opposite , you just agreed that there was a problem and that maybe you'll get charge pumps for your new machine in the hope it fixes things.

There is no point in me sending you a PM which you say you'll ignore, i am posting here so that people need to know to do things in a safe manner and anyone posting unsafe advice deserves all they get in the way of unfavourable comments.

I knew you misread what I wrote or intended anyway. I wasn't suggesting that he leave it with just a switch, but that a switch would be safer than not. I also posted to let him know that I too have similar issues with my C10's.
It acts differently on my lathe than it does my mill, though the settings, motor controllers etc are virtually the same.
The mill and router act similar even though the items are totally different as are the settings.

The switches are a stop gap, period. They are safer than not running with them.
(from my first post)
"I intend to get the Charge Pump boards though and install those."

"Intend" isn't a maybe. I have asked about charge pump boards repeatedly on this forum and have had no answers other than buy boards with those on board. I did that and the board turned out to be faulty. $140 down the drain.

I have found this board.

It is only a recent addition to his line up and what I have been looking for.
I haven't heard of any feedback from this yet, but will first test it on my new mill.
If it works as advertised, I will order three more.

I am not as sure that it is a C10 problem as it may be both Mach 3 and the C10.

Now as for my ignoring you, I would ignore anyone that resorts to name calling yada yada yada. Many other ways to get your point across. A little maturity on your part would not hurt either.

Here is how I have it wired. Output 1 & ground on the c-10 is wired to the input of the relay, the relay has 5v coming in from a 5v power supply. I have included a link to the relay manual as well as a photo of it.

The main reason I think that something is up with the c-10 board is that even if I have the computer disconnected from the BOB ,if there is power to the board it will send 5V to all of the outputs, this does not seem correct if there is no signal to the input then why the 5v output?

I am not at work today so I am sorry if my wiring is vague.

Well Lee as i am 59 this year i think senility rather than lack of maturity would be the reason.

I would get a bigger buzz helping you fix your problem than name calling

OK i have lots of CNC4pc stuff and think its great.

Now the first thing Lee and Kencor1

This function of the C10 board

• External Enable Pin (EN). The board has a pin that allows you to enable/disable all the outputs at once. The board requires +5vdc in the EN pin. If it is not present, it will send all the outputs to ground. You can use this to enable or disable the system manually, or you can install an external Safety Charge Pump or other external device.

That 5v should be wired through a hardwired Estop button and all other devices really, that should be a minimum so hitting than switch YOU KNOW IT WILL BE SAFE

Kencor1

Try to test where the problem lies, power the RBX-1 but with the outputs from the C10 removed so that only the 5v supply and a spindle is connected if the spindle runs then the problem lies with the RBX-1 or the way it is connected/wired

Phil, I tested the relay and it is working fine. I did notice that if I unplug the parallel port cable coming from the Smooth stepper board the relay will shut off. I did check if if it was the ss board by bypassing it and using the parallel port from the pc and the same thing happens. whenever the board is plugged in to the computer it will cause the c-10 board to activate the outputs to 5V. I just want to know if this is normal. I seems to me that when I 1st hooked up the relay that it was not happening (but I may not be sure). I will be adding and charge pump board for sure. But in my "novice opinion" the c-10 should not be sending 5V to the outputs unless told to.

Thanks,
Tom

I have added photos of my control cabinet.
