There is probably (hopefully) a very simple answer to this, I just dont know what it is!
I'm Using Mach 3 and a CNC4PC C11 Breakout board.
I want to use the relay on Pin 1 to turn the spindle control on, the relay on Pin 16 to set the direction and the 0-10v on pin 14 to control the speed.
I can get the speed output (all works fine) but I can't get the LED on pins 1 or 16 to light up. I have tried other pins and they work fine and have checked pin 1 on the lead going into the board and that has 4.7v (and goes on and off as expected).
The voltage from the VFD into the common of the relays is 12v which should be fine.
Is there something else required to get these relays working or have I blown it up before I've started?
-
Also when I look at the diagnostics screen. Pins 1,2 & 3 are always lit for some reason.
I have turned off all input and outputs but they are still lit????
-
And one more thing......
I can't get the charge pump to work either. Most of the outputs do seem to work other than these 3???

Hello HurcoMatt,
Just wondering if you ever got this situation resolved.
I am having similar problems and no response from Mr. Duncan as of yet.
Thanks,
RC

Not yet but they did come back to me thje same day with some questions so hopefully it will be resolved soon.

Still having problems here.....Any luck there Matt ?
I'm stuck right now.....waiting for Mr. Duncan.
Keep me posted if you will,
RC

Dear Sir,
Someone brought this message to my attention (thanks). You mentioned you were waiting for an answer from me, sorry, but I am not aware of this, when and how you tried to contact me?
So it is just outputs 1 and 16 and the Safety Charge Pump that are not working? Please check the following:
- Are the LEDs for pins 1, 16, and 17 on the board lighting?
- What about the LEDs in the diagnostics screen in mach3?
- Have you tried a different cable?
- Could you measure those output pins with a multimeter? In the port itself, the cable, and terminals on the board?
If you are positive the board is receiving the signals, then it must be that one of the buffers or optoisolators could have gotten damaged. I know how frustrating this is, but keep in mind that it is better to have to replace this than to have to deal with a problem with the PC. These chips are easy to replace, inexpensive, and readily available: http://www.cnc4pc.com/Store/osc/index.php?cPath=38_43.
Please let me know how it goes.
Thanks,
Arturo Duncan

I am also having identical problems.
- Are the LEDs for pins 1, 16, and 17 on the board lighting?
No
- What about the LEDs in the diagnostics screen in mach3?
Yes
- Have you tried a different cable?
No, but I will.
Did you ever get it resolved? I'm still waiting on another C11 board from Arturo, but I believe he's away for a few days.

There are some issues with some of the C11's, one of which is... the DB25 connector is evidently from a bad production run.
Loosen the screws on the connector housing of your printer cable and gently move the cable end left, right, up and down and see if there is intermittent continuity. (temporarily set the outputs "Active" in Mach and watch the LED's) I was able to temporarily salvage output 16 and 17 this way until I got my replacement board.

RC and others, were you able to get these issues resolved?
I was actually thinking about getting one of these but now I'm hesitating.. :-\
thanks-

Hey Dave,
I'm not having the best luck with the 2 that I have.
I will wait for Mr. Duncan to respond before making any final determinations.
Here is a problem I am having with the 2nd one.

Ok, then it looks like I'm looking around some more- ;)

Hi all, hope everyone is doing well!!
budman68, what other bob's are you looking at??? I'm on my third cnc4pc bob.
Thanks olf20

OLf,
any c11's buy any chance ?
RC

No, two C1's and I just ordered a C1G. The first board looked like it was a proto type. No sockets for the IC's.
The second board failed while I was trying to get the Auto Z zero working. The chips that were sent did
not match up with my board, so I still don't have a machine running. I just ordered a C1G to get the machine
running while I try and sort out the problems with the second C1.

Olf, I'm really not sure what to use now but Hood speaks highly of the PMDX 122 and I've also heard many good things about the Boards from Bob Campell. These seem a little overkill for what I want as I was hoping to get away with a lower price as I'm not hooking up any motor drivers to the board that I'd be getting, I just want more I/O s for relays and other gadgets :)
Thanks,
Dave

Have a look at the PoKey, just got one a few days ago and so far its looking good :) Its nt a breakout but will be very handy for lots of extra I/O
It is a USB device that can be used to connect 55 digital Inputs or Outputs, five of which can be analogue, at the moment though Art doesnt have the analogue done in the plugin but if there is enough interest he will do it.
I have been messing around with it for the last few days, had a 12 position rotary switch hooked to it and made a small Brain up so I can set the FRO from 1% to 150% in 12 stages, it works great. If the Analogue part of the plugin is done a Pot could be used instead to give infinite FRO and only use up one of the Inputs. Each pin can be set up as either an Input, an Output or even a keystroke.

Meant to give a link and also mention that until 10th Aug Mach users get a 15% discount and free shipping. I have no affiliation at all with the product, just saw mention of it on the Yahoo group and decided to give it a try for a pendant I am making for the new mill.

and the Discount CODE: MACHCNC16

Hey now, that's very interesting. It was a bit more than I'd hoped but jeez, look at all those I/O's!!! :D
Thanks as always!
Dave
-
You would have to check up to see if there is enough power for relays, not really read the manual so not quite sure, I just saw it as an excellent board for connecting up external switches etc

Indeed, I'm reading up on it now (pdf manual online). Thanks for the heads up-

Have you tried a different cable?
No, but I will.
Checked the cable out with a continuity check. Each pin checks okay.
Checked the port on the board as well. Checks out okay from pin-holes to the soldered points on the board.
Tried moving the cable and the RS-232 on the board. Everything is rock solid.
Still can't get pin 1 to light up, nor 16.
