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 attac…
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:http://wiki.evilmadscientist.com/Spherical_media
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.
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…
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 mi…
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…
When 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, inexpen…
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 s…
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:http://wiki.evilmadscientist.com/Hatch_fill
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.
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:Basics: Picking Resistors for LEDs
You should also be aware that the candle flicker LEDs cannot be used in series with each other, which we dis…
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.
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 ha…
These forums and email are the support methods we offer. We do try our best to respond personally and quickly to posts or messages. I'll be following up to your most recent email messages shortly.
The article on using the extended firmware is here:http://www.evilmadscientist.com/2010/the-expandable-larson-scanner/If you are building the project up on the IX PCBs, there are several changes you need to make. Did you build your project taking th…
Are the boards all built up with the modifications required for the extended scanner? Is it possible you have a chip with the default Larson firmware on it?
Regarding stretching: eggs are not uniform, and 150% is a general guideline, not a hard and fast rule. However, you may have your pen motor a little lower than it should be. The tapering at the tips may also increase the impression of it being squis…
I would suggest that you use the preset hatch for fills, which you can find information about here:http://wiki.evilmadscientist.com/Preset_hatch_for_fillsSince it gives a continuous line, it is much faster than separate lines, each with a pen down a…
