Newbie- Keiling KL-350-48 and G540 hookup Help

[FandZ]

Please help reunite a father with his family by helping me figure out how to hook the G540 up to a Keiling KL-350-48 power. Wiring is a mystery to me. I'm more mechanical. If I don't get this machine done soon, I have feeling my family will adopt a new dad...

OK, I believe I have enough hooked up to get my g540 out of fault. But I'm not sure if I have everything connected right. I still haven't hooked up my stepper motors but from what I'm reading it should still come out of fault.

Is my wiring right? Are there any settings in mach 3 that I need to do?

MY printer port is set to EPP in the bios.

Anyways, I'm at a lost.

I'm attaching a picture of my wiring.


Last Q, I'm useing a 3 prong power supply cord for my power supply. There are 3 wires. Black, white, and green. I hooked the black up to L, white to N, and left green out of the loop. That is correct, right? I wouldn't want to send the negative to ground. Little LED lights up on the power supply so I think it's right.

Whew! A lot of miswiring there. GOOD THING it did not come out of fault!

FIRST of all, DISCONNECT terminals 5,6,8 and 9 from both G540 and power supply. CONNECT the green wire from AC plug to GRD terminal next to L and N. L should be black wire, N should be white wire.

NOW, the reason that it won't come out of fault is that your EStop switch is connected wrong. Move the negative wire (green wire in your diagram) from the green terminal to the remaining RED terminal on the EStop switch. (BOTH EStop wires go on the red side)

Now it should come out of fault. If it STILL doesn't come out of fault, it's the charge pump. Do you have the PC on and connected to the G540? Is Mach3 up and running and your charge pump activated?

Look VERY carefully at terminals 10 and 11. ALL wire strands should be buried into the terminal. NO copper showing. ANY loose strands could short against the case.

Yea, I was thinking something wasn't right. I was trying to get it to match the suggested wiring diagram that came with the g540.

OK, I've made all the changes and still am in Fault mode. Basically all I have connected now is:
Pin 12 to V-
Pin 11 to v+
pin 10 to e-stop 1 red
Estop 2 red to V-

Should I try changing that charge dump switch or mess with any settings in Mach3?

YAY, it was the charge pump! I was so worried I fried something. Now I just need to figure out mach3

Thanks CR for comeing to the rescue! I'd probably have the fire department out here if it wasn't for you.

Holly crap You are the man! Now all my Axis's work! Almost tempted to wake the kids. Thanks for your Help CR. Woohoo.... I need to cut something.

Sorry if this is beating a dead horse, but what kind of cooling setups do you folks run with the 540? I ran across the chiller system but would rather save the cash. A heatsink and any 24-50v fan do the trick? Anyone ever fried one of these things? Also, planning to mount it inside of my pc case. Any foreseeable issues with that? Thanks for hanging in, despite my noobness.

rewster,

Spoiler alert! A cheap computer case fan works just as well as a very expensive heatsink. The most important thing is airflow and a 12V fan provides plenty of it.

Thanks for the reply. I have seen that link, was just wondering what people were actually wiring up to their boards. I'm stoked to use this thing, and don't want to risk screwing it up. Looks like a cheap fan will be the way to go.

One more quickie; do I run db9 pins 2,3, and 4 to ground, or just pin 3?

[CoAMarcus]

rewster,

I assume you are talking about shielding, correct? Pins 2, 3, and 4 are tied to ground so it does not matter which one you use.

great, that's what I was looking for
