  • Hi The above line does not work as is, delete the " " from the end to get it to work. ( ͡° ͜ʖ ͡°) RGDS Ragnar

  • Hi. Quote; Yes, figured out where that came from pretty quickly. Is that good or bad? The motor voltage check can still be implemented by checking for the appropriate firmware version first. I have tested it - it works. Manual check NOT importa…
  • Hi. Quote; Also, if that's not your screenshot, where did it come from? The screenshot is from my "addition" to the eggbot extension. My version can be found in this thread. http://forum.evilmadscientist.com/discussion/337/checking-ebb-motor-vol…
  • Hi. Hi Brian. Any chance of getting an updated version anytime soon? Would really like to have a working solution (from Inkscape) incorporating the 'long moves'. Quote (April 30th ;-) ); I'll let you know what's going on as soon as I can squash th…
  • Hi. The file was most likely produced using Inkscape and saved as PDF. By 'opening' the file in Inkscape and saving as SVG you should be good to go. I have changed the stroke to red as this is a requirement by some of the laser cutting services. B…
  • Hi Brian. I have moved the servo horn on the servo in order to lift the pen a few mm off the egg when in the reset (middle) position. I ended up on having pen up / pen down values of 24 and 19 respectively in Inkscape. When resetting the EBB the se…
  • Hi. Making changes to the eggbot extension to take advantage of a home command might be within my capabilities - worth giving it a try - the difficult part for me is to wrap my head around the OOP (Object Oriented Programming) part ;-) Where did y…
  • Hi. I can live with the servo in center at reset - my 'solution' is just to move the servo horn so this becomes the 'default pen up' position. I'am sort of glad you got the timeout as well, I was about to suggest that this 'bug' would not become a…
  • Hi. A few observations on the 2.2.5 version.   Inkscape is unable to make any plots with this version. Inkscape receives an incorrect return on Pen Up/Pen Down as it's inserting a 'Null Move" SM command according to the EBB Command manual recommend…
  • Hi. Great news Brian. I just made a plot in Inkscape of a one layer "Wave Winding" coil. (See Wave Winding machine post.) The image is 102400 pixels in width. This plots fine. For a 10 layer coil the width will be 1024000 pixels which does not work…
  • Hi. The plot is  a copy of "Zentangle art" by Stoshi - see her blog page here: Stoshi's Blog ( I got her permission to post the image as long as she got the credit she deserves.  ) She called the image "La Bella", a great work of art! I traced the …
  • Hi Brian. Testing of 2.2.4 started, Operation of servo now back to 'normal'. ;-) Will try some of my plots. Plots started OK. (What's the difference between EBF_v224.hex and EBF_v224.unified.hex? (I have loaded EBF_v224.hex to my EBB board) Edit…
  • Hi Windell, good point, I'll try to increase the current and see if that helps. What's the max steps per second you can achieve? Would you ever want to plot at those speeds anyway? When I try to plot at high speeds the pen arm goes 'haywire'  when…
  • Hi. What's your speed per step setting? I found anything over 700 would lose steps. RGDS Ragnar
  • Hi Brian. Thanks for the feedback, I will try the different suggestions to your 'microstep' fix - as a 'hardware guy' I just assumed the problem to be in the code!! - (As Jerry Pournelle (Byte Magazine - Chaos Manor - now Circuit Cellar) - once sai…
  • Hi. First "proof of concept" run of Eggbot Coilwinder complete. I abandoned using the pen arm as a 'wire guide' as it was 'fiddly' and did not work very well due to the varying distance between the wire feed and the coil former. Made a 'addon' from…
  • Hi. As you see from the graph in the middle of the egg the "aspect ratio" is 1.5. The circles have to be 'elongated' 150% in order to plot as round circles on the egg. See this post as well. Here are the text output of the plotted data; Pen Radius…
  • Hi. Please be advised that the "aspect ratio" of 150% is valid only for the max diameter of the egg. ( Windell, you are absolutely right, 150% is spot on for a chicken egg with 42mm diameter and 58mm length. My previous value of 148% is only valid …
  • Hi Great idéa. Not much of an adaptor is needed really. If the pen arm horizontal part had a "V" shaped "hole" (to take different wire diameters) to guide the wire you would only need a 'device' to keep tension on the wire. As the pen arm is moving…
  • Hi. When examining your "Calibration Plot" and really trying to understand how the diameter of the egg affects the shape of plotted objects I made a small program in python to plot the values. I have used a term I called 'Aspect Ratio" which is th…
  • Hi You are doing it right setting the arm to 90° when the pen is down. I use the "paper under the pen" trick as well. Make sure your pen tip is in the center of the egg along the 'long' axis (from tip to tip). The pen arm motor height is also 'cri…
  • Hi. From looking at your egg I would suggest you check two items. First the servo pen up and pen down positions has to be set fairly correctly. I set the up position to lift the pen just a few millimeters off the egg surface and the down position s…
  • Hi. "404 YOU HAVE REACHED THE END OF THE THINGIVERSE. THERE IS NOTHING AWESOME HERE... YET." The correct link. Nice work! RGDS Ragnar
  • Hi. Yes, we are interested. Please upload. RGDS Ragnar
  • Hi. Thanks Windell, I'll take that as a compliment! I rather trade "wearing out" a servo every four years for high quality plots. The servo is a "low cost" item anyway, some of the pens I have experimented with costs more. Having a servo and a few…
  • Hi. Getting a reply from "daxbot" is higly unlikely - the stats from the forum states that daxbot's last visit to this forum was in October 2012. quote from earlier post in this thread; We can certainly create new fonts and characters, and there h…
  • Hi. Just tested my eggbot with a 9V supply, no problems plotting. RGDS Ragnar
  • Hi Your supply is probably OK for driving the eggbot. The problem seems to be your current potmeter setting. With the pot at maximum the current to the motor is too high - the driver chip protection circuitry kicks in - causing the jittering. Try s…
  • Hi Thanks, just an 18 hour drive! I'am on my way! RGDS Ragnar
