Need help

[Tsooko]

Hey Dan:
Nice boxes. I ordered the g 540 from another place before I got your post. Too bad, your price is better by a small amount. Nice website. I'll have to see how things go when I get the gecko. We may yet do some deals. ( I like the scanner)
I am interested in the pin layout.
Your wireing description matches what is in the Techno manual, so I just need to know which motor wire goes to which pin on the Gecko. For now I am going to see if I can use the m-100 box, and I still need to buy the mach3 software. So it will be a little while longer yet. Waiting is a *****.
Thx for your help.

Thats easy take the two wires that are on pin1 of the stepper and connect them to pin 6 of the db9 that goes to the G540.
Pin2 goes to the db9 pin 7 of the gecko
pin 3 goes to the db9 pin 8 of the gecko
pin 4 goes to db9 pin 9 of the gecko
Use the gecko pin 1 and 4 for your current setting resistor.
Pin 2 and 3 are not used on the gecko db9
But you will need to run the Ground on the stepper motor (5) side fro the limit switch and connect that to thepower supply ground. Last connect the limit switch output pin 9 of the techno to terminal 1 of the G540 for the X axis, terminal 2 for the Y axis and terminal 3 for the Z axis

Thanks Dan:
The gecko has been shipped. I'm hoping it will be here by the end of this week as long as it doesn't get hung up in customs. So sooooooon!

A little update: Got mach 3 today and the g540 should be here any day now. It is out of customs. and on it's way

Dan: What size resisters and what do they do?

Thanks Ted

You need the proper resistor to set the current running to the motors from the 540. The instructions from the 540 will explain the simple formula used to calculate the resistors and also where to put them. They are cheep and might be found at any radio shack.

It's here

I am totally surprised at how small the g540 is.
Customs only charged me the gst which is a sales tax and that's ok.
I went and got all the electronics and a motor so I can wire everything up here at home.and test it out. Pics and text to come!!!

Couldn't wait:
Here's what I got done so far...First I gutted the m100 box, taking a ton of pictures so I could remember where everything goes, especially the wires. The motor drives, the breakout boards and the power supply came out the only thing I left in was the main plug as it has a ton of wires and I didn't want to be concerned where they went back. Then I cleaned everything, as parts were full of dust, this was a working machine after all.
There were some holes in the back where componants were attached So I took a piece of abs sheet plastic and made a plate. this covered the main hole. Then I cut a pocket in it that the g540 would fit in. I then mounted the plate in the original hole using the old screws and fancy nuts. Looks pretty good huh? That's it so far. Took me about 3.5 hours, I move sloooow. and take lots of breaks. Tomorrow the power supply goes back in and I'll hook up some wires.

Here's some pics.

Got stumped
Now I have put back into the box, the fan, the power supply and the front cover with all the switches. Using the pics I took I hooked up the wires but not the gecko drive so I could test the voltages coming out of the power supply. I could not get a dc voltage reading on the output side. When I switched over to ac voltage, I got a reading of 26 volts. Don't know if this would have blown the gecko as it take between 18 and 50 volts DC but I am not hooking it up!!
So I'll look around locally for a power supply, if I can't find one then it's back to mail ordering one.
The adventure continues!! It has been said "it's not the destination... but the journey"

Hey Guys
Some progress and some questions. I got a power supply. 24 volt, 6.5 amp out put which is as close as I could get to the original power supply except this one is dc not ac. It falls into the range the g540 requires. (18-48 volts) The motors are 2.5 amp rated which means that I need 2.5 k resistors on each axis for the current set. I could not find 2.5 k resistors. I got 2.4 and 2.7 k so my question is which one do I use? Can anyone tell me? Since the resistor goes betweem pin 1 and pin 5 of the output side of the gecko on the db9 cable the 2.4 will let a bit more power through, will that damage the motor circuit? Or if I use the 2.7 will that choke the current to the motor too much causing a performance loss?
I'm going to hook up the rest of the wiring and will take some pics as I go and will post them latter. Thanks in advance.

I got the power supply hooked up and wired to the gecko 540.
When I power up, the leds that indicate power or fault do not light up. The computer is not yet hooked up, but should these lights not come on ?

Interesting developement. I called Gecko to see if they could help me out. Talked to Marius and he walked me through the hook up. After checking out the wireing and testing to see if I had burn't the fuse ( I hadn't) we put the drive back together and it worked. The lights went on like they should have. There was a poor connection somewhere. Remember I know nothing about electronic and Marius had to walk me through every move, he spent almost 1.5 hours with me. Now that's service!!! Thankyou, thankyou, thankyou! He also gave me a bunch of hints on what to look out for as I hook up the rest.
I'll work on it this weekend and should have a motor working by the end of it.
I'll report more then.
