In order to have action, you have to have a plan. So far there has been no consenses on what this thing should do, how big it should be, what the budget should be. So far, ErNa has about the best...

Stefan,

You asked for my opinion so I will provide it, but please keep in mind I am not a big fan of buying tools that "look like a tool".

The price is reasonable at somewhere between $300 and...

That is interesting. I see there are no labels on the buttons so I am assuming that location of the button causes some sort of event relative to the length of the wire?

Very neat looking machines. How do they work? What do they do? What does the controller board look like? How do you program them? Where is the keypad and monitor? How fast do they move?

A picture...

Graham,

Yes, the one I showed in the video posts earlier would be a gantry machine - it's mechanics are like that of a gantry crane. I agree with your assesment that a bridge machine is...

Thanks Dave,

I think I got it now.

Hi Dave,

Yeah I get what they both do, I just don't understand why I can't use CMPS for comparisons of both positive and negative numbersall the time.

Chris

I think I have a can of fairy dust laying around somewhere, I can just sprinkle it on a workbench and we will have anything we want for free ;-)

You have got to do a lot more research on this...

Hi PASM folks,

I am curious as to why we have both of these. CMPS can work for sign and unsigned comparisons. So why do we need to have CMP?

Chris

After thinking about this more, perhaps it is something along the lines of viral videos. There isn't anyone behind them marketing them, they just catch on like a flash fire in a frying pan. In any...

Being a guy that never could understand C programming, I thought for sure I was trapped in the world of BASIC. When I started tinkering with micros, I had to find one that could be programmed in...

That statement sums up a lot of this discussion. Many people want open to equal free, and that is okay if everything we need is free.

Chris

LOL! I know the feeling Graham, been there done that too many times.

Chris

I don't understand most of the thinking associated with "open source" and the demands people put upon comanies to follow the concept. I think parallax does a pretty good job of keeping things open...

Graham,

Looking at the FDM head you have at your disposal, does it look like something that can be made by the average person here on the forum? If not, do you know of a source for them? The...

As both Graham and Bruce pointed out, it would be best to work from the "tool" backwards through everything. It seems as though the primary goal is a 3D printer, so start with the "print head"...

Bruce,

You made a pretty fantastic claim, expect to be questioned about it. I guess the real question is, What is it going to take for you to share it?

Chris

A basic CNC control is certainly possible with the use of Prop chips, I have been working on it for about 2 years. I must clarify though that my controller also uses two Atmel chips. I have linked...

Count me in too

Chris

didn't really watch the half time show, but did watch the game. YAY PACKERS! Keep the titletown tittle going!

Ah, yes, now I understand about the problem with the hardware.

There are pull downs on these outputs so that the inputs to the stepper drives are not floating. That part is safe and I have...

Hi MagIO2,

Thanks for chiming in. As I stated this whole concept is new to me (even though I have been using the prop for a couple years). Anyway, I am not sure if I actually need to load the...

The new prop will not be in a DIP package but don't let that scare you away. Someone will create modules so that it can be used by those not capable of dealing with surface mount components. I went...

Thanks guys,

For clarification in my particular example. The COGs that I would be doing this with are written in PASM and I am already sharing variables through the hub using rdlong/wrlong...

Hi folks,

On my project that I have been working on for a couple of years, it is reaching the point where memory is becomming a problem on the prop. Up until now I have not looked at the memory...
