Thank you for your incredible feedback! I'm very happy you find my project useful. We seem to think alike. My goal in sharing the models was to help inspire new users (like myself) in getting involved with making things and 3D printers are all the rage. I have certainly learned a lot. Hearing feedback like what you just gave me inspires me to continue on. Thank you for being a wonderful person by leaving such nice compliments.ozcroz wrote:Hey clintonsam75, I think your work is really good. Posting it here is so helpful to users of FreeCAD!
I am new to FreeCAD so it is inspiring to see what can be done with this fantastic CAD software. I too would love to build my own 3D printer so your work is educational for me.
Did you design the printer yourself or is it based on an available model? Information about this and where to obtain the parts would be appreciated. If this is not allowed on the forum and you are happy to do so you could email me the information.
Thanks again for your excellent work and the kindness to share it with us on the forum!
In answer to your question, I got the idea for the design after watching this video https://vimeo.com/40914530. After watching that video, I Googled "corexy" and the top site for me turned out to be http://corexy.com which gave me all the information I needed to know about how it works. The only part of the design they explain, however, is how the "corexy" concept works. But, after I took a real close look at the machine, I saw how it was assembled and used the way they assembled their machine as a guide for mine. The biggest problem is that they use aluminum for their frame. That's not exactly something the average Joe knows how to machine. Here in Korea, I don't even know where to buy aluminum. About all that is sold in a "hardware store" here are screw drivers and drills. Good luck finding a rotary saw. You can buy the blades but you can't buy the saw. Go figure. lol. So, I decide to use wood. That's a material just about anyone can use. Sure wood warps over time, but it's extremely cheap and replacing wood is not that hard. My biggest problem was knowing how thick the wood needs to be. Wood is heavy so it shouldn't be too thick but it needs to be thick enough that it won't bend. So one day I noticed that a box my wife painted in an art class she took in our neighborhood used wood that is 1 cm thick. So that's how I decided on the thickness. I have not visited a wood shop yet to see what thicknesses are available and to look at the strengths. Maybe I'll do that next week.
Now as far as where I bought the parts, I ordered almost everything off of E-bay. I filtered searches by "new", "buy now", "free international shipping". There are a few parts I bought from Sparkfun and Robotdigg. Also there were a few items that I ordered which never arrived. I think the delivery man got angry at me for mistaking him for a "phisher" (phone scammer) and threw my packages away instead of delivering them. But still, I know that I could pay less than what I paid if I went through different channels in the future.
It will be my pleasure to post a full list of parts, their prices and links to where I purchased them. Just give me a few days.
