Nice graph and great info. When I created the simple calibration plot, I expected some of my circles to actually plot as circles instead of all ovals. After looking at your graph, I realize I need to adjust my pen arm motor. I’ll play around with that and see how it affects the plot. It definitely takes some experimentation to get the plots as expected.

Thanks for telling me about thingiverse.com.  

I uploaded my file and egg photo to: http://www.thingiverse.com/thing:300570.

I found my problem. In short, I increased my Computer Sleep and Display Sleep time in the Energy Saver of the System Preferences to 2 hours. They were set to 15 mins and my plots were taking much longer. I happen to notice that the plot stopped when my screen saver turned on. Although, it was not my screen saver but my Computer Sleep. Since the change, I have plotted a few things that took some time. The last plot was an svg that contained 5000 points and it took 45 mins to complete.

I feel confident that this was my problem. Thanks for all the responses. This might be worth putting in the wiki. That is, make sure your computer is not set to sleep during your plot.

Well, the problem is not fixed. It’s just inconsistent plotting on my MAC. Sometimes it will stop while plotting my stipple file. I can then go manually control the plotter through inkscape and it works fine. I start it again and it may or may not complete. Small things seem to print fine. I don’t have any problems on Windows. The plotting completes every time. I also do not think it is my MAC or its USB ports (I’ve used different ones). Nothing else connected has any issues.

MAC version: 10.9.2

Inkscape version: 0.48

StippleGen 2 version: 2.02

EB Firmware version: 2.0.1

Thanks for any help,

Thomas

Thanks for the quick reply. I originally thought that this was a software issue of some sort due to the ‘IndexError’. However, I found that this occurs anytime plotting is in progress and I unplug the USB cable. I do this since the cancel button does not work. I was able to print my stipple file on a Windows XP machine (yes, I still have one), so the file must be ok. After reading the link you supplied about the hardware problem, I setup the Egg Bot back on my MAC, but did not use the USB extension that I did on my previous setup. This time it worked fine and would plot the entire stipple.svg file. Cool!!

Here is the EBB firmware version:

I asked the EBB for its version info, and it replied:

  EBBv13_and_above EB Firmware Version 2.0.1

If there is a newer version, I will load that.

Thanks again for the help.
