Great– sounds like you’ve got it under control. :)

It sounds like the actual issue is unrelated to registering different colors. Here’s something to try: Run a short example file twice, drawing the exact same thing twice without moving the pen, and make sure that it retraces its steps well.

You haven’t hinted at what kind of machine you’re using here. If it’s an EggBot, please read through our quality troubleshooting guide: http://wiki.evilmadscientist.com/Eggbot_Quality_Troubleshooting

I’m sorry to hear about the bad battery. The Chronodot is supposed to remember the time set on the Bulbdial automatically, so that you don’t have to set it again after unplugging it momentarily. 

Make sure that:

– The Chronodot is oriented the correct way

– The Chronodot is installed at power-on time.  The initial check to see if it is present is only conducted at turn-on time.

– The soldering on the headers is good

– The soldering at pins 27 and 28 of the chip, the two pins closest to C6

– There are no stray connections on the back of the board in that area

You may also want to check the voltages on the Chronodot pins, and make sure (with power off and chronodot battery out) that there are no accidental zero-resistance paths between the chronodot pins and ground.

I should note that the new release of the EggBot software (v 2.5.0) works with Inkscape 0.91, and is compatible with 32 bit and 64 bit versions on Windows.

If you wanted to just turn on both, with their own separate power supplies, with a single switch, you could just use a regular DPST — double pole, single throw — switch. But if you also want to preserve the separate 3-position switch on the EL wire, you’ll need separate switch for that.

Hi Ragstian,

Yes, figured out where that came from pretty quickly. ;)

For better or worse, this feature won’t work on most EBBs because of the firmware version… Once we begin to ship EBBs that do have this feature supported, we will add something like this. Our original goal was actually to automatically check the motor voltage every time that a command was sent, to let the user know that it wasn’t plugged in. Adding a manual check is also (obviously) possible, but isn’t quite as important.

[Windell Oskay]

That’s very odd. It sounds as though there may be wiring issues, or possibly issues with one of the sockets?

[Windell Oskay]

Check that the IC is oriented the correct direction. Check that the IC is not getting hot.

Check that you have ~3V (logical high) at pin 1 (reset) and pin 20 (Vcc). Check that no two of your pins are shorted together (solder bridges, etc.). 

Check that you haven’t reversed the LEDs: Your kit should have a spare LED in it. With power on, touch its leads to the leads of one of the LEDs on the PCB, on the back side. Try both orientations, see if it lights.

Download RoboPaint RT from https://github.com/evil-mad/robopaint-rt/releases/latest

This is a processing example to drive the WaterColorBot, also based on the same EBB controller that the EggBot is.  Use the scanSerial() function there to connect to the EBB.

You may need a replacement EBB, then. Please contact us by e-mail, or via our contact form, to set up an exchange.

The extensions currently work with Inkscape version 0.48.5. 

They will also work with the 0.91 prerelease, but the installer does not yet know this, and you may need to manually install the extensions.

If none of the motors are working, the most likely situation is that the power supply is not plugged in or connected correctly.  Check that it is. You should still have lights visible on the EBB, even after you unplug the USB cable.

If the servo motor’s “up” position is lower than the “down” position, try swapping the two numbers that you have in the Setup tab, so that the “up” value is now lower than the “down” value. Either number may be larger.

For the stepper motors: I’m not sure exactly what you’re describing. Are the motors “energized” when you try to move them? That is, do they resisting turning by hand at all? One thing that you can try as a test is to do is remove all of the wires, and swap them, so that the motor 1 connections now drives motor 2 and vice versa. If you do that, are you still unresponsive?

[Windell Oskay]

The current version is 2.4.0, and I’d suggest that you upgrade to it. You can download the installer here: https://github.com/evil-mad/EggBot/releases

Also, if that’s not your screenshot, where did it come from?
