Painting will probably be later next month. I'll sure to post an update when I do!by RichardSalinas - Look what I made!
Large 18" 460mm tall sculpture made on the RoboSculptor. You can see it here. More details can be found at 3D printed Sculptureby RichardSalinas - Look what I made!
As part of my printer testing I took the time to make a more interesting test print. A fractal based form. My 4 year old twins love it. They think it's a dinosaur.Pictures hereby RichardSalinas - Look what I made!
ABS 3mm. The design is basically the WhiteAnt 3d printer / CNC machine designed by Patrick Hood- Daniel and can be found at BuildyourCNC. I made the print bed bigger, changed electronics, extruder, etc. I'm waiting on linear rails so that I can replace the y-axis system. I plan to build a heat chamber and other systems in the near future. By the time I'm finished it will be deceptive to call iby RichardSalinas - Look what I made!
I had a successful test using my full bed size of 350mmx220mm. You can see it here:Blogby RichardSalinas - Look what I made!
I'm getting close to printing a full size (350mmx220mm) print. I just calibrated my printer and worked out a few bugs. If interested in the WhiteAnt or experimenting with larger build envelopes then start here: Blogby RichardSalinas - General New Machines Topics
Im getting close to having a modified version of the whiteant printing. Here's a link to see a video of it going through a mock print run. Blogby RichardSalinas - General New Machines Topics
I also like the feature of having the LEDs on the v.3.3. I wasn't quite aware of how nice of an indication they are until I ran my test.If you can, could you link the old forum post for the pololu's current rating discussion? And thanks for the positive feedback. This is an ambitious experiment on my part to see what I can make and if it will work for me. Maybe others can learn from my meanderinby RichardSalinas - Controllers
Once again thanks. I set up 1 axis on the RAMPS board with a v3.3 driver and it works great! You can see my setup here: Blogby RichardSalinas - Controllers
Once again thanks. I'll definitely look into the circuitry and figure out if the mods are beneficial. I do plan to keep the stepper drivers and motors the same for all axes. I plan to use the typical pololu and NEMA 17 for 1 (and later 2 extruders).by RichardSalinas - Controllers
For some reason the link didn't set up. I fixed it, so it works now. I'm posting it here as well. Blog I have 2 Gecko g251 drivers that are probably dead. My 3.3 drivers are in the mail. I'm also waiting on my arduinos since they are fried because of a dumb mistake I made with my power supply. Apparently when s**t happens it can really happen hard. I hope my luck returns.by RichardSalinas - Controllers
Thank you very much. This is what I needed explained. I think I can go forward now with more confidence. Richard I initially decided to use the Gecko drivers ( I bought 2) , but with my various problems decided to try the v3.3's and purchased 4 ( they are 1/2 the price of a Gecko) hoping that they would serve my needs. My reasoning was if I couldn't get it to work , I could fall back on using enby RichardSalinas - Controllers
Interesting idea, but I've got another solution that I will be testing soon. I've built a repstrap and designed a heat bed that will concentrate more heat on the corners and less in the interior (where I would think the internal heat build up would dissipate more slowly). Maybe this will even out the cooling a little better. You an see my bed here: Heatedby RichardSalinas - Look what I made!
Thanks NoobMan: If you could clarify a few more things please. Is the Reset connection ignored on the v3.3. On the pololu it's taken to sleep on the driver, so doesn't really go anywhere on the RAMPS board. This is where I find things confusing. Also if you are familiar with the Gecko g251 driver, there isn't an Enable connection. Does the Logic Ground connection on the Gecko serve as theby RichardSalinas - Controllers
I could really use some help sorting this out before I burn out more drivers. I'm trying to find out exactly how to hook up Makerbot v3.3 stepper drivers at 24v on a RAMPS 1.4 board. I know the board is designed for Pololus, but I'm trying to use the RAMPS board on a repstrap using NEMA. 23s. I also have successfully burned out a Gecko g251 and maybe even a second one. If anyone could take the tby RichardSalinas - Controllers
I've been sampling textures and large volume printing on my Prusa Mendel. This is my largest yet. Anyone who's interested can check it out on my blog : http://reprap-art.blogspot.com/2012/05/3d-printing-natural-forms-ii.html. Some may find it useful.by RichardSalinas - Look what I made!
After discovering Autodesk's Softimage and what I could potentially do with it to create my art, I decided I needed my own 3d printer. The Reprap project has been the greatest place for me to start. Now that I have completed my Prusa Mendel and made some useful prints, I've decided to start on a repstrap. This video shows the process of making A Greg's Accessible Extruder.
