Chronicle of a Geek. (Jgro Build)

[voltsandbolts]

Well, let’s begin at the beginning shall we. I started my build with the controller box and drives. I used a surplus enclosure from a company that makes printing equipment. I picked up my drivers and steppers from a yard sale for $50 and only one drive is a bit flaky.

The motors are Power max II and the drivers are PacSci-6410 (micro stepping) from Pacific Scientific, very nice for the money.

The power supply is one I striped out of a telecom equipment rack I spotted at the dump. It’s 50 volts at 10 Amps, and the price was right……FREE!

Photos soon…

altogether folks.. photos, photos, photos, photos, been waiting on this for a while now......

[Glidergider]

This is too good to be true. Keep going!

Sorry guy’s I know I have been delinquent in my duties, but living in New England means some times you have to put your hobby on hold and go sand 800 feet of driveway.

I’ll try and get a few photos up to night…..if I’m not too sore.

I love the title of this thread "Chronicle of a Geek". Now show us just how Geeky you are. It's really hard to be geekyier then me.

Ok, time for the long-awaited first photos…

1 & 2 are the driver box and drives there is a small power supply from a scanner in there too, to run the fan and for limits and anything else that might need +5 or +12 volts.

3. is the main supply 50 Volt ,10 Amp. I added circut breakers, the two little black squares on the end closest in the photo.

You remind me of myself, sometimes using the table saw as a workbench, then you got to get it all off, what sort of driver are you using that you are powering it with 50V?

[voltsandbolts]

Hi Tjord,

Yes, although I have counter space, things just gravitate to the table saw…. I don’t know why, they just do.

The drives are from PacSci-6410, micro stepping. Full step down to 1/50,000. I have work with these drives in the past so I snapped them up when I saw them.

Some of the futures are adjustable:

Step Size
Damping control
Idle current reduction
Settable current.

[voltsandbolts]

And they run at up to 75 Volts....

[tajord]

Wow, i'm not familiar with that board but it sounds cool, 75 volts you say, I'm probably not gonna even run half that, I'm wondering what performance you'll be getting when you're done.

[voltsandbolts]

For software I am using, AutoCad, Ace, and TurboCNC. I check my code by running it on MicroTech CNC Simulator.

What are you guys using? Or going to use?

[tajord]

Say... what are you gonna be cutting with your cnc?
