Description

Plus Graham Robertson arrives to Factor e Farm

A

You've got a little bit of explanation for what's going on here.

B

Yeah we're using this power supply, although it can only kind of up to 5 f's to power. The stepper drivers here, which are connected to the organ microcontroller. The microcontroller is sending step in direction to the drivers, and the drivers will energize the stepper motors and we're going to be testing out Oh axes right now. We're having issues with the stepper motor is drawing too much current. So.

A

Laughter, why is the top one different another one? So I did you choose the different.

B

And fortunate, oh.

A

Do we want to switch that to to the other ones exactly I can find them for you, yeah sure, see and that's three individual boards just on a makeshift heatsink for four separate overs, okay,.

A

Under full power it would require a fan or something like that.

B

Yep because think a lot but.

A

Tell me, but just tell me the toolchain though, so what are you using to make the star okay so.

B

You got the computer and you need g-code file, which is computer-aided manufacturing file and you take a G code file and put it into a g-code streamer and that essentially sends the g-code through this list available to the arduino ide controller, the microcontroller picks it up and interprets the g-code using grb l, which is flashed out to this wagon controller beforehand. In preparation and that's pretty much it. You.

A

Just okay: it's over here.

B

And interpreter there and then the stepper drivers can take care of the rest. So.

A

You've got what are you doing in G ctrl well,.

B

Jesus Cairo two main functions: one is to take G code from your computer and stream it into the Arduino microcontroller. But you can also use G ctrl as jogger, which you use the arrow keys and the page up and page down easy.

A

B

Control three axis and.

A

B

Interprets that and move the stepper motors up by a bit depending on how much ok.

A

So let's say: if you go to kind ng.

B

You get the whole team Porgy and then that.

A

Then allows you to just load a file that you want to stream. Ok, all right.

A

Set the schematic of that layout layout of the driver board, okay layout of the driver board.

A

You can use the exciting times, I'll just start something all.

B

A

What's that you gotta put in Hilo yeah, this is gonna move. Here's.

B

The four-inch I.

A

Love this shot. Look at that the torch table. Little tractor in the back new guests, errands straight from Colorado, may be coming back. Graham just arrived, Graham I, consider yourself, Graham.

C

Robertson from Texas uh-huh.

A

Why I come at the factory farm to.

C

Learn fabrication skills have no experience. This is all very new to me, but uh it's very interesting I've been following you guys for a long time. So.

A

What are you hoping to get out out of the time that you're here.

C

Training in fabrication then, hopefully well, it's kind of self. It well not selfish, but I want to build my own micro tractor. It's not selfish, but so.

A

You've got a design of the micro track. That's how is that coming along? It's.

C

Coming along well, I did some of those modifications. We talked about right.

A

C

Of there's some kinks to work out.

A

Are you interested in learning professional cat on top of Sketchup yeah.

C

Yeah I'm going to learn how to do all the drawings for you, Oh excellent.

A

Tuesday's our first session with instructor Yoon, so Holly tuesday, from eight to eleven.

C

A

Gabi already wants to be be there. Yeah graham wants to be there. Who else wants to be there all right? You want to learn some professional cat, absolutely I'm there, okay plan, so yeah, we'll look forward to seeing how the tractor evolves and then pick up basic fabrication skills and then actually build it out. Yeah.

C

I have no expectations of how long it's gonna take to learn all this, but once.

A

I do so we want.

C

To get on the prototyping yeah.

A

So you're a definite case of a person. That's that's interested in learning and we'll do that and have you put to work on building stuff yeah as soon as we can sure yep.

C

All right, Graham.

A

Welcome to factory farm. Thank you.
