Hi Art,
First, check that the stepper motor wires are securely held in the screw terminals by giving them a gentle tug to see if they might come loose.Did you go through the Making your first plot section of the documentation? It sounds likely that you need to adjust your current, and the procedure is on that page.LenoreWhen you reprogrammed it, you overwrote the original firmware. You can reprogram it with the default firmware, which is available from the programming article. More details are on the documentation wiki.
We prefer the Pager Motors for Bristlebots, as they draw a little less current than the 6 mm ones. However, either will work. The larger ones will wear down the battery sooner. We like to use CR2032 coin cells as they are commonly available, inexpensive, and 3 V. Operating voltage means that is the range they can work within, where 3 V is the voltage they are designed to be used at.
If it is going five ahead each time, then only six of the 30 are lighting up. Which six? Knowing which ones can help us diagnose the problem.
Unfortunately, I think it is just a batch of servos that had bad quality control from our manufacturer. We’ve been doing more testing here since we discovered the problem, and this batch has a higher than usual failure rate. We’re working with our supplier on the issue, and we’d be happy to send you a new one, if you want to contact us.
There are several methods of filling it in which are described here:http://wiki.evilmadscientist.com/Creating_filled_regions
The hatch fill extension is the easiest way, and you can find the details here:If you want, you can scale it up to fill the vertical height of the template. Go to Object –> Fill and Stroke and set the fill to none and the stroke to black. If you plot at this point, it should show the outlines of the logo.
Great! First step: open up the EggBot template. Select the logo from your file, copy it, and paste it into the template.
Also, the file will work fine. I’ll follow up with steps on how to use it once I know about where you’re at.
First, I’ll need to know what step to start with. So, first question: have you successfully printed the “Hello World” file on something using the EggBot?First resource for you, which talks about appropriate resistors for various power supplies and LED colors:
You should also be aware that the candle flicker LEDs cannot be used in series with each other, which we discuss here:It’s likely that you have a bad servo. One thing you can try is different servo positions, as some servos seem to be happier in different “up” positions than others. In any case, please contact us so we can send you a replacement.
Hi Mari,
I’ve followed up by email–your error message images didn’t post, so please send those to me via email and we’ll go from there.LenoreOne of the most common places for sharing digital designs is Thingiverse. There are quite a few EggBot and WaterColorBot designs posted there.
The 5th LED in that group (D405, I think) is likely shorted out. Check the leads on the back to see if something has bent or caused a short there. If the short is above the PCB but under the LED, you’ll likely need to replace that LED. If the LED has burnt out and fused to cause a short, then replacing that LED is still the answer. There should have been a few extra LEDs in your kit.
