The maximum recommended pen weight is 1.6 oz (45 g).
As an open source hardware project, you can learn from it and borrow code from it without purchasing it.Regarding the number of segments, the 17th segment is actually the decimal point, which means ours technically have 18 with dual decimal points. 17 segment is the usual name used for this kind of display.Our go-to example for driving these displays is the Alpha Clock Five. There is example Arduino code there which you may be able to use as a basis for other projects. You can also look at the hardware documentation to see how we drive the different length segments and decimal point.
Adafruit likely has example code for the various components that you linked to– their learning system has lots of resources.
The wiki has a separate login from the EMS forums, and is not associated with wikipedia. You’ll need to create a new login there (sorry!)And no– you’re welcome to post things like this here– but I wanted to make sure that resource was included in the discussion here.
Great comparison, Shel! I’d also encourage you to post brief descriptions on the pen choices page of the wiki.
You may want to check the settings in the timing tab.
Do you mean that the servo motor is not lifting the pen slide? You can use the toggle up/down commands to test this. If the servo is not moving, check the connection of the black-red-white cable to the controller board to see if it is securely attached to the bottom set of pins. If the servo arm is moving, but the pen slide is not moving freely, it would be helpful to know that.
I’ve never come across cork balls before. If the surface is smooth, it shouldn’t be a problem. We have a list of types of things to print on here:
We take safety very seriously, and do not recommend using lasers without a protective cover. That said, there are many ways to mount various lightweight tools to the pen holder.
To add to what Windell said, I just added AxiDraw to the front page of the wiki so that it is easier to find.
Would you contact our shop about the possibility of sending your EBB in for a check?
Hi Jhon,Did you try the hatch fill extension mentioned above?
By triggered, do you mean that other motor was energized (but stayed still) or that both motors moved the same amount?How many steps were you telling it to walk for your test?
There is normally a sharpie checkmark on the side of the terminal block (closest to the mounting screw) for a tested EBB, and I wanted to find out if yours had been marked as tested.One set of the header pins at the other end of the screw terminal allow that button to be wired up off board, so if those pins got bent during shipping, they could possibly be causing intermittent contact.If you’re interested in the design of the EBB, you can find the details here:Yes, feel free and follow up here, or drop us a line through our contact form.Best,Lenore
Hi Shel,Nope, that’s not normal. I would suggest checking your EBB to ensure that there isn’t any stray debris shorting the button. Also check the pins near the servo motor cable to make sure they aren’t bent and possibly shorting each other. You might also try pressing the button during a print to see if you get the same behavior. It’s possible that pressing or flicking the button to see if was semi-stuck could solve the issue.Would you let us know what type of EggBot you have? Does the EBB have a checkmark on the end of the row of screw terminals?If those possibilities don’t pan out, please contact us about sending your EBB in for inspection.
