The servo control signal is not an "on/off" signal-- it's a command to move to a particular angle. If you need an on/off, I'd recommend putting it on a second I/O port, just so that you can always switch back and forth with software alone.
There is not, but you can add one. The EBB has four three pin "servo outputs" available. The lowest of them (B1) is used for the pen lift servo. The other three (B0, B2, B3) are available for your use.
What you will need to do is to modify your sof…
Not directly; the EBB operates at an internal logic-level voltage of 3.3 V, and its I/O pins are just below this. If you need 5 V, you'll need to provide an external logic-level shifter.
OK, great. If you you do want to use an alternate power supply, it should be 9 V DC, regulated, with at least 1.5 A true capacity, on a 2.1 x 5.5 mm center-positive plug.
It sounds like you didn't manage to actually install that copy of Inkscape on your computer. Or, if you did, it ended up somewhere besides where it was supposed to be.
That folder location is only present on recent versions of Inkscape, so that may …
Please make sure that you're using the original power supply that came with the kit. Try plotting at a lower speed, perhaps 10%, to see if that helps. And, check to see if you're using the latest software. The current version is v1.2.2.
Does the machine feel like it is physically damaged or broken, with parts loose or stuck? For example, when you move it to the home corner before printing, does it feel like something is jammed?
Opening Inkscape for the first time, you may need to right-click on the Inkscape icon in your Applications folder, and then select "Open" from the pop-up menu there.
Have you been able to print the "AxiDraw First" example file successfully?
If you want to control 128 sensors and LEDs, you'll need 128 inputs, and 128 outputs. If you're arranging these like the Octolively does, with one IR LED per sensor, you'll also need 128 outputs for those LEDs. Not sure how you get there with 15 ex…
@OldFarmer: This is not a related issue; I'm going to close and lock this topic after this reply. If you have additional questions, please start a fresh discussion topic.
(And to answer your question, the Legacy AxiDraw does not use the same softwar…
A new ATmega164 comes with the fuses set to run on the internal oscillator. The fuse settings are essentially independent of your code-- if you set the fuse bits to continue using the internal oscillator, then it will continue to use the internal os…
We've seen an abnormally large number of bug and issue reports from people in a few different reporting locations (forums, user groups, formal bug reports), and we are temporarily advising against upgrading, especially on Mac. (I have every confiden…
I'd advise trying without the power supply plugged in until that you've established contact. Try a different USB cable as well, if you have one.
One other thing that you can try is to open up a terminal and try ls /dev/cu.usbmodem* , to see if the …
If you can understand the reason for the dropout better, you'll likely understand what the right remedy is. Yes, adding extra capacitors near the power supply lines of touchy components is often helpful. But, your power supply likely has much larger…
You might want to measure the actual current draw on those servos. A quick search on the internet suggests that they might draw as much as 1.2 A peak, and if so, your power supply may not be sufficient-- even if you add some beefy capacitors.
We are working on a new extension that is able to convert paragraph text into single stroke text, in the Hershey Text style, with a limited set of fonts. However, since it is using different fonts, there will never be an exact layout match. (Linebre…
We have not finished testing it. (It will work, but does not yet.) I would advise holding off for another week until we have a chance to give it the full workup. (We're also finishing up a round of other software updates.)
It's plausible, but not necessarily easy. Converting from dvi to svg is a specialized operation. I tried to install a program called dvisvgm, but only allowed about half an hour to try to round up and install the dependencies, and did not get it run…
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 s…
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…
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 curr…
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.
