Interesting. I’d suggest check the resistor color code on R6 to see if is the right type of resistor (1.5 k should be brown, orange, red, gold), and try measuring with your ohmmeter both ways across that resistor _after_ you fix the issue with the shorted pins.
The Mega Menorah 9000 should be able to be stay on indefinitely.If something got hot, that sounds like something was genuinely amiss, and there are a few different things that might have gone wrong.The buttons do have a specific orientation, but (1) they slip in easily the correct way and can only be forced in the wrong way through protracted wrangling that involves weird bending of the pins (2) they can’t sit flat against the board if they’re in the wrong orientation. Even if you did manage to get them in the wrong way, that alone would make the button nonfunctional, but it should not overheat or cause other trouble; the switch is protected by R1, which limits the current through the switch to a very modest 5 mA. Similarly, a short circuit within the switch should only be able to cause a maximum of 5 mA current. And, 5 mA at 5 V should limit that to 25 mW of power, which is not enough to get “very hot” on a component of that size.My best guess is that there was (possibly, is still) at least one short circuit on the board. With power disconnected, use your multimeter to check all four pins of the switch, to see how it is connected. Test first on the other switch (“Night”), to see what a (likely) good switch should look like. Two of the pins on one side are electrically connected, as are the two pins on the opposite side. Then, when you press the button, all four pins should be connected together.Check to see if the two buttons respond this way. Also, check to see if they appear to be connected as per the schematic. S2 should connect to Vcc with a button press, S1 should connect to GND with a button press. Also, and importantly, check that these lines are not connected to other lines that they shouldn’t be. Also check, for example, that neighboring pins of the IC are not connected, and that the ends of nearby components such as R1 and R2, are not connected.Please let me know what you find.It’s a digital high; please check the datasheet for what the actual voltage is under these conditions.
Please look at the datasheet for the ATmega164 or the Octolively as needed for your reference about which pin does what.
I’m not sure what your question about LEDs is about– LEDs are lit by current flowing through them. However, you can’t get current to flow with them without voltage. Similarly, voltage alone isn’t enough– there needs to be a complete path for current to flow through. As to what controls the pins, it’s the software (firmware) stored in the device.The current release version of Inkscape is 0.91– if you’re using a pre-release version of Inkscape (especially one so far ahead as 0.95) that might explain the issue.
Can you please say what it is that you have that is “0.95”?
EggBot software has been pretty seamless across the 32/64 transition; it’s a set of python scripts that are not pre-compiled for either 32 or 64. However moving from one version of Inkscape to the other (or worse, having more than one on your system) can potentially cause certain types of misconfiguration. I’d recommend affirmatively deleting the version that you do not plan to use, and then re-installing the Inkscape extensions.
The error message indicates that the software cannot find an EBB. So, if Windows can see it but the Eggbot software cannot, that _usually_ indicates that something else is intentionally blocking the port (as antivirus/antimalware software sometimes does) or unintentionally blocking the port (as software that accesses other serial devices sometime does).
Yes, that’s the same error, and it sounds like you have the driver installed and everything. It also seems like your USB cable is functioning and plugged in.
Usually in cases like this it turns out to be that something is blocking access to the port. That could be a different device (perhaps a printer or some other type of I/O device), or anti-malware software that does not allow access to the USB port. Please check to see if there is something like this which might be interfering with your access.On the “unable to draw object” issue:
You seem to have found a bug that no one has ever reported before. I think that I can see how that can happen by looking at the source code. I will create a formal bug report for it, and it will be fixed in the next release of the software (hopefully sometime this month).In the mean time, please select the objects that you would like to fill before using the Hatch Fill command. (You can use the Edit > Select all in all layers command to select the objects that need to be filled, if you would like to fill everything.)We have generally found that the method of previewing paths in the document (Section 10.2 of the user guide, “visualizing paths in your document”) to give a reasonable preview of what will actually print. If you find that using this method does not give you a reasonable preview — that is, if the machine is doing something significantly different than what you see there — please contact customer support directly, and send us a copy of the SVG file that you’re trying to print. We may be able to help identify the issue.I understand what you are saying about using Inkscape when you are used to Illustrator. I personally feel the same way when I use Illustrator or CorelDraw– and we have (a surprising number of) other users who love Corel, and tell us the same thing when they have to use Inkscape or Illustrator.You’re trying something that (in all likelihood) no one has ever done before; I’m not surprised in the least that you are finding it frustrating.
I haven’t heard of Graphic before, nor seen a file that it generates. And, regardless of whether or not it uses vectors for drawing paths, you also need to be able to export them into a vector file format that Inkscape understands.Inkscape does not have _any_ fonts– it only uses the ones on your computer. If you need to have font interoperability between Inkscape and whatever other program you’re using, you’ll need to have that font installed on your computer. (This is the exact same thing that would be true of any other program that uses fonts.) If you cannot install this font on your computer, then I’d suggest converting your text from into vectors before exporting.The “bitmap” warning is triggered any time that there is an image file within your document. And, it won’t be triggered unless there is an image file there. As I haven’t ever seen a file created in Graphic, I do not know what kind of an image is in there, nor whether there is any vector content in addition to the image.If you would like to send us your SVG file (and possibly the original file that you exported from Graphic), please contact customer service directly. We might be able to provide some insight.One other trick might be to use a polarizing filter; reflections can be attenuated with the polarizer at a certain angle, relative to the rest of your image.
The recommended maximum weight of the pen is 45 g. 2 ounces ought to be fine, more than that if you can anchor the base.
(I’ve moved this to the AxiDraw forum.)
The AxiDraw normally does not apply downward pressure — it allows a pen to fall under its own weight. That’s likely not enough pressure to activate the keys on a mechanical keyboard.We’ve done a demo once with the WaterColorBot (another machine of ours), detailed here, holding a stylus. If you’re using a capacitive-sensing trackpad (the most common type), you’ll also need to add a ground connection to your stylus. (There’s a ground tap available at the pen-lift servo, so it’s quite possible.)Can you please say which device you are asking about?
