C11G, Gecko 203v and Mach 3...connect what where?

[teamtexas]

I just got the C11G BOB and I'm not sure on some of the connections. I plan to use an E-Stop but I'm not sure if it needs to be between pin 10-5v or if I should use the 5v-EN & Pin 10 on the input?? I also want to use my one of limits on X,Y & Z as my home input. Can the C11G do that or do I have to have seperate switches for home. I know I can set it up in Mach 3, just not sure about the BOB.

I think the BOB requires 12vdc and 5vdc. I plan to use to wall warts for that and I see where the 12vdc/gnd connects but do both dc supplies have to share a gnd? I see several spots for the 5v/gnd to connect, I just don't want to let the smoke out!!!

I think the 203v will connect to Step, Dir & Common on the output terminals. I've selected a small jumper that says 2-3... comm=gnd on the BOB. Is that correct?

I plan on using the saftey charge pump thats built in so the jumper is on 2-3 and I will assign pin 17 to it from Mach.

If anyone out there has this combination please tell me if I'm on the right track.

Hello Dan,

I just hooked up a C1G BOB but I am not using all the features, just signals for the steppers. Yes, change the jumper to pins 2,3 for common ground for the G203's and connect a wire from each common on the 203 to a "COM" terminal on the BOB. I connected mine to the "COM" terminal near the step and dir terminals on the BOB so I know what they are for.

I did a control box awhile back with the same components.

I bought the A4 power supply (5v/12v) from cnc4pc. It comes with a panel mount connector wired for the c11g board. It has 3 wires (5v, 12v, and a common ground) works great for that board.

E-stop: I took the hot wire off the 5v/EN, took a wire from the 5v to the e-stop, took 2 wires from the e-stop, 1 of the wires to the EN pin and 1 wire to pin 10.

Jumpers: com is ground, and charge pump is pin 17.

Thanks for your replies, Hey Tauntdesigns is your C11G a 5.4 version? The terminals location you have to power connected to on mine are GnD/5v/5v.

Dan,

No, mine was an earlier version. I didn't realize they had changed it that much. Sorry about that.

My board needed 5v@2amps and the new one states 5v@1amp

Sorry again,
Jack
P.S. EDIT: The E-stop part didn't change.....

Taunt, I've connected the 5vdc and the 12vdc and have my estop wired like yours is, but for some reason I can't get the output led to light. I have a 5v Led lit and the 10 pin input led is lit. I started Mach 3 and set the estop in the pins and ports and tested it. Mach sees it just fine. I originally had the charge pump enabled, but changed the jumper to try to bypass it and get the output led to light. No Luck! Any suggestions?

Dan,

Do you have a second wire from same side of the e-stop as the pin 10 wire, running back to the EN pin? The EN pin must have 5v for the outputs to work.

Dan,

I went out to the shop err.... garage and started everything up and took some pictures.

1st pic is from the power end showing the e-stop right above the BOB.

2nd pic is from the 5v/EN side of BOB. In this pic you can see the lights that are on when the e-stop is released and the reset in mach3 has been reset and ready to run.
Labels of the lights that are on:
pins 10 and 17
output status
5v and 12v power

I also went in to ports&pins-inputs tab to see what my e-stop settings are:
E-Stop
Enabled (Check Mark)
Port # (1)
Pin # (10)
Active Low (Check Mark)
Emulated (X)
Hotkey (0)

Cheers,
Jack

I've got it wired just like that. I even checked the voltage at the en pin and it had +5vdc. I'll have to check to see if I have a 12vdc LED...I didn't have one lit??

I was having a problem with my board when I first put my box together. I accidentally figured it out. I have to start everything in this order. I was thinking it had to do with the charge pump, but maybe it was the output.

I boot the computer, start up Mach3, plug in BOB power supply, turn on driver's power supply, release e-stop, and reset mach3's reset. If I shut down mach3, I must unplug the power to the BOB, re-start mach3 and then plug in the BOB again.

Arturo said the newer boards had been fixed, but I did notice that the manual said the system needs to be running before powering the BOB. Could this be it?

Jack
P.S. I looked at the new board's manual and didn't notice a 12v light. I may have missed it, I'm not even sure if it (new board) needs 12v to operate.....

[teamtexas]

Well I thought I figured it out this morning. I tried to remove the estop from the equation and hardwired the en/5v. No change! I'll have to go out and try the order you have suggested. Only problem is the BOB and drivers are both controlled by a common swithch on the AC side of my system, so the will start at the same time. But my estop is a momentary switch so it has always been closed on start up. I'll hold it down while starting up the BOB/Driver switch and see if that helps.
Dan
PS. the only thing I think the new board uses the 12 volts for is the analog speed contol option that I'm not using.

[tauntdesigns]

I think that only the mach3 needs to be on first. The first time I got everything to work.... after that I always started everything in the same order, but if I understand the manual right: the system (Mach3?) needs to be on when the bob is turned on.

Not sure about about the momentary switch.... I used the press/twist release e-stop from cnc4pc.

Turn off the e-stop and the charge pump in Mach3 and use the hotwire between the 5v and EN and see if you are getting a light on the output status. After taking everything else out of the equation, if you still don't get a light then you know its not the e-stop.

Jack
Edit: does the momentary switch allow the 5v to pass through until it is pressed?
