It does have an mSATA port, for plugging in a SSD. But, hopefully the micro-SD alone is adequate.

I just got it, and was surprised by the lack of a VGA port. Going to have to get an adapter...

Ok, if the gizmosphere 1 works fine, hopefully the gizmosphere 2 works as well. That's what I found available, and ordered.

I'm sure I'll be back with lots of questions......

Thanks!

Anyone successfully using LinuxCNC on a single-board computer?

Looking to run LinuxCNC with a Mesa card (probably a 7i92) For packaging reasons, i need a single-board computer (not enough...

I wasn't previously aware that there were 2 classes of motion control boards. Buffered, and real-time. That one bit of information has been very helpful

I think i'm going to go with LinuxCNC...

i guess "stuck" with Mach is not the right way to say it. As to some background, I'm really considering only the few most popular systems out there at this point (Mach3 and LinuxCNC) i value proven...

Hi everybody,

Hopefully this is the right forum for this question. There are so many sub-forums, confusing as to which is the correct one.


Looking for a single board computer / motion...

That seems to have done the trick. Thanks!

I would think this should be the original behavior of the machine. Without the macro, It still seems way too easy to accidentally disable the...

I'm trying to set up my machine limits, and i'm having difficulty getting the behavior i want. FYI - I only have a physical switch on one end of each axis (wired separately)

I'm trying to get...

thanks for that link to the 1284 standard.

I wish i had read that earlier. My implementation does not match the reccomended configuration. Instead of 1.2k pull-ups to +5, i've pulled...

It's a SERIAL connection. Don't try to hook the cable to your parallel port, you might fry something.

There are quite a few communication programs out there. google "rs232 DNC software" any...

INPUTS

I'm interested in the conventional inputs (10,11,12,13 & 15). I know how the outputs work. You can't "set a state" for the inputs from the PC end. It seems the state is set by internal...

That's the bit of information i'm really looking for. I should have asked my question a little clearer.


I don't specifically need to pull them down if they are purposely being held high. I...

Hey guys,

Quick question. do ALL pc parallel ports hold all of their input pins high in the "default" state, and wait for them to be pulled low by external circuitry? Or is this a behavior of...

Don't worry about it. I already have an Ah-ha interface (2 of them actually) but i'm missing the card that plugs into the PC, therefore they're completely useless.

However, i have half the...

I haven't documented it, but it handles on/off control of the spindle, x,y,z stepper driver connections (both drive output, and limit switch input), U-axis output, tool length probe input, and...

very interesting reading there. Will definitely have to try "sherline mode" with my old, non-delayed interface.

I was hoping not to have to use any special software modes that may exist in one...

I have zero information regarding the 4400. I'm concentrating on the 2200/2400 right now, but more info is always good.

I believe it's definitely possible to reuse the dyna stepper drives, A...

We'll let you know when we figure it out.

I have information to indicate that the 2800 is controlled almost identically to the 2400. the same interface should work.

I agree with BEKX - if a ball starts to form, that means it's time to stop and re-grind. I use thoriated for aluminum, on an old sinewave machine. It stays fairly sharp for quite a while. I...

in order to get all that info, we need way more information about your setup.

Are you using the Dyna gear reduction system with your new steppers, or did you connect them straight to the screws?
...

We had some off-line discussion and Matt has prompted me to get working on this again.

My original plan was to offer an interface card that replaced the RS232 connector on the side of the cabinet...

That's currently the direction i'm heading, however I was trying to avoid that.....i'm only mediocre with electronics. Doing it with software would make my interface less complicated, and given my...

Ok, so posting this prompted me to do a little more experimenting.

Looks like the dyna drives use a fixed "power-save" period of approx .08 - .11 seconds after the last pulse, where they shutdown...

I have some old stepper drives that i am trying to retrofit to PC control, and i need square waves as a step pulse. the "on" and "off" time should be approximately equal. Can EMC do this?

As...

I'm not 100% sure exactly why the drives don't step properly, i'm just giving everybody the results of my testing. I haven't figured it out completely, it's just a hypothesis, based on the fact...

Oh, and by the way. Yes, the original dyna motors are kind of on the small-side power-wise, but they do run through a 10x1 reduction gearing system, which means they can produce plenty of torque on...

I reverse engineered out all the pinouts that you require. (posted below) I was attempting to develop a Plug & Play PC interface, but i have just about
given up on it. Posted is the results of a...

Nobody knows? Well, i guess i'll have to try it.

Pin 1 is listed as a "control port" along with pins 14, 16 & 17. Do these have to be set as either inputs or outputs as a group? or can they...

Ok, i got my machine running. Still trying to tune it, but seems like it runs.

I don't currently have the machine E-stop hooked up to the PC. I know i need to do this, and it's on my "to-do...

No, nothing is set in stone yet. I have a working prototype, but it needs a revision.

That's an interesting thought. I set it up for best PC board layout, and the least number of jumpers, but...
