  • If these are traditional RGB 5050 LEDs -- with two pins for each LED element and no built-in controller chip -- then there isn't any one particular quick and easy way to do it. Rather, you're now in the territory of microcontrollers, and individuall…
  • Yes, that is the correct source image. This was not made by StippleGen, but with a similar program that we have written in Processing, which creates "string art" style drawings like that. We have not yet released the software -- we are still tweaki…
  • You are absolutely welcome to post things like that here, including any appropriate links (thank you for asking). I think that the forum does still disallow image uploads, though. There's rarely a compelling reason to checking for DST more than onc…
  • In our experience, 8 out of 10 times, something like this is caused by a poor solder joint. If you can't find the problem in the first pass, please let us know and we can make some additional suggestions.
  • Try to (gently) rock out one or two of the LED modules-- if you can swap two of them, that should be able to confirm for you whether it's the LED module or the board. Since all of the segments are out, it would certainly suggest that it's not the L…
  • The AxiDraw is an A4/Letter size plotter. It is not designed for plotting larger things. We are considering an extended X-rail version -- please contact us directly through our contact form if you're potentially interested in that -- but the Y does …
  • Please read the answer above about .ps and .eps files. You do not necessarily have to import into Inkscape-- there are various ways to drive the AxiDraw including a low-level serial interface. Printing directly from within Illustrator is not support…
  • Native parsing is done from the SVG file format, and people often start with files in one of those three formats. However, the answer in general is "It depends on what's in the file." The AxiDraw is a pen plotter. Its sole function is to plot vecto…
  • I don't know enough about the environment that you're working with here to make any informed guesses as to what the issue is. However, my instinct would be that a function named something like "writeLine" (as opposed to "write") would have a built-i…
  • There is not separate timing used for the QB command-- if timing is working correctly for other commands, it should work there. You might try checking the EBB Command Set Documentation as your reference on what exact characters it should send back.
  • The svg file is directly "handed" to the python script. It is not modified, so far as I know. If the QB command works differently than on our hardware, there must be some difference in how it's implemented. If it was genuinely identical, it would …
  • I don't have experience with this chip, but if it's giving an output, then you may have a different peripheral having control of that pin. You'll also need to make sure that your MUX settings selects AIN0.0 to be active (rather tan AIN0.1), and tha…
  • No, that's not normal at all. If it's been doing this since your first plot, it sounds like your machine may have had some damage in shipping, or perhaps there is a problem with the power supply. Please contact customer support directly so that we c…
  • If you want to vary the speed within a stroke, then yes, you'll need to use a low-level interface of one type or another. You can either use the direct serial interface (EBB commands), the robopaint API, or other means to do so. If you can say what …
  • There is not natively support for per-object drawing speed variations, but you can probably work around that by using the layer-based controls. You can find documentation for them here: http://wiki.evilmadscientist.com/AxiDraw_Layer_Control To use …
  • Nothing in your description would suggest to me that there is any kind of "shorting" or overcurrent event going on. If there were, I'd expect it happen on either computer, and I would not expect resetting to make a difference. Unplugging the power …
  • Unfortunately, not enough for us to recommend it yet. They did put out a quick bug fix release (0.92.1) in February release to correct a couple of major issues. However, they are still recommending that Mac users stay on 0.91 for the time being. B…
  • Yes, that is all correct, with the note that the firmware does not have a mode that directly supports a clock spanning two units; you will need to play with the firmware to get it to do this function. We would recommend that you leave the Chronodot …
  • The displays are socketed, and can be removed with some careful wiggling. Our store does also sell the displays separately, so there's no issue there. The displays are a bit challenging to drive, since the different segments take different voltages …
  • Did you follow the directions from the AYAB web site, or from our web site? For use on Mac, I would _highly_ recommend following (to the letter) the directions on our wiki: http://wiki.evilmadscientist.com/AYAB_Mac_Installation
  • AxiDraw is only an option for newer beta versions of RoboPaint; we are expecting a new beta release (after a long delay) towards the end of this month. It sounds like you're not having the same issue with RoboPaint-- the issue that you're having is …
  • From what I understand of this issue, the root cause is that AutoCAD produces actual dots at those locations-- is that correct? If so, it's not really an issue with Inkscape or what it's doing, but with how AutoCAD creates the files. Does AutoCAD ha…
  • Please read through sections 10.1 through 10.6 of the AxiDraw user guide, which discusses what the AxiDraw does (it draws the lines that you ask it to), how to preview how your artwork will plot, and discuss the various types of inputs that you migh…
  • Yes, a few tips. First, it's helpful to stand above the machine, to the extent possible, while setting the pen and paper position. It's easy to get some degree of error just from basic parallax, and keeping yourself higher (or the machine lower) can…
  • Do you get any kind of error message? Or, does it act like everything is working, including taking the time that it normally would to make a plot? If the latter, then it sounds like the power supply is either not plugged in or not working. If you ar…
  • Bryan, Please start a new thread or contact technical support directly. The issue that you are describing does not sound related to the one in this thread.
  • I don't think that I've seen this particular symptom, but it is possible to damage the ICs through a few different ways. The most common way is overvoltage on the power supply pin. Make sure that your 5 V power supply really is 5 V (not an unregulat…
  • No; there is no g code generated in the EggBot software, so if you wanted to get some it would need to be generated in the first place.
  • Yes, the AxiDraw can be used to produce readable text that is similar to handwriting. There is a significant difference between how writing looks when written with an actual pen as opposed to a inkjet printer. Anyone who looks closely will be able t…
