Re: Pen Plotting Tool Chains? - 11 years ago

So i have found a solution. I export a PNG or JPG from PCB editor and open that in shapeways 2D-3D converter. Found on their website. Then save that file. The filetype is x3db. open this file in Netfab Basic and export as STL. Open this in slicer of choice and set up the proper settings. I still have to get the proper slicer settings (KISSslicer in this case) but the results are promising. See

Re: Pen Plotting Tool Chains? - 11 years ago

Thanks for the input guys ill have a look at all of those options. CNC machines can handle certain G## movements for circles where as i believe most Reprap firmwares can only handle straight lines so a circle turns into a bunch of short lines. I was doing some thinking and i would not be surprised if there was a firmware i could load up to my reprap instead of marlin that could handle the differ

Pen Plotting Tool Chains? - 11 years ago

Hi all, I just want to preface this post by saying that i have searched the interwebs far and wide in search of an easy way take an image file and generate gcode for plotting on my printer. Most of what i have found is not geared towards the typical printing toolchain, and is more geared towards EMC2 controlled machines. I have seen videos on youtube of people plotting with reprap, and i have as

Re: Making PCB's with a diodelaser - 11 years ago

Got it, thanks Viktor. I was hoping to hear you were using a reprap with a laser on it but that is ok. I had an idea last night and i think i can turn a 2D image of the PCB layout into a 3d STL file and slice it with really small layer heights to get multiple passes with the Sharpie. If all goes well i will post some pic here or start a new post. Thanks -Erik

Re: Making PCB's with a diodelaser - 11 years ago

Viktor, This is very cool stuff. Thanks for sharing. I am also curious about your tool chain. My plan for doing my own PCB are to strap a extra fine sharpie to my reprap and then etch the board. I am having a hard time finding a toolchain to go from PCB layout -> Gerber -> Gcode for the reprap. Can you please enlighten us all on your process? Many thanks, Prost!, -Erik

Re: Changing Layer Heights Affects Extrusion Widths - 11 years ago

Very cool. Ill have a look through that, once i get through the back log of other things i need to do. I noticed that KISS comments what is going on in the Gcode, which i assume is how you are able to parse the gcode to change flow rates. How would this be done in something like slic3r? Looking at dimensions? hmm.. ill have to ponder that for a while. Ill give your script a try at some point and

Re: Changing Layer Heights Affects Extrusion Widths - 11 years ago

So it seems this issue we are all having with hole sizes and extrusion widths have been around for a while. with different theories on why and how to fix it. Very interesting and challenging which is one thing i like about 3d printing with an open source printer. Oh the fun of it all. I will try some things tonight with KISS, i am still getting familiar with it. Ill let you all know what i find

Re: Changing Layer Heights Affects Extrusion Widths - 11 years ago

@Just Curious, You are right, perhaps i am making too much noise. I have done a fair amount of digging and reading and research and everything i have found points to Slic3r having an issue with extrusion width especially with holes. I have calibrated my printer per Slic3rs recommendations and according to them that is all i need to do in order to get correctly dimensioned parts. I do like Slic3r

Re: Changing Layer Heights Affects Extrusion Widths - 11 years ago

QuoteSublime Also when I say the extrusion is too wide is not a bug where Slic3r puts out too much plastic for the width it has decided to use.... That makes sense. I guess i hadnt thought if it in quite those terms. I am going to use the clay example when explaining this to others. As far as the skin thickness goes: if i do a singe wall thickness part, should this be set to my extruder width?

Re: Changing Layer Heights Affects Extrusion Widths - 11 years ago

Hey Sublime, Question for you really quick. Im tryin out KISS and i was wondering what your setting for skin thickness is set to. Default is .8 and extrusion width is .5 I am changing the e width to .53 as per your calc. good work. Bookmarked indeed. I am going to experiment with a thin wall test and measure it and see what happens, I am assuming a single wall will be the extrusion width, and a

Re: Changing Layer Heights Affects Extrusion Widths - 11 years ago

Thanks for the replies guys. I read through your posts from that other thread. I have read that several people have had issues with slic3r hole sizes and am suprised that there wasnt a bug request for it. Ill try KISSlicer at some point(maybe tonight) and ill use your calc sublime. You had mentioned it several times in that other thread and i should have heeded your advice. I will try it and le

Changing Layer Heights Affects Extrusion Widths - 11 years ago

Hello all, I am not new to these forums by any means but my account is no longer active or something. Its been a while since i have posted anything. Anyways here are my settings: Printer of my own design(ill share it here once my write up is completed on it.) This printer is based somewhat loosely on my(now disassembled) prusa.
