3d Printer Part 10

I got my motors I paid $39.99 for

and have already tested them and determined their pinouts. That black thing on the breadboard is an H bridge motor controller and I don't currently know how to limit current on that kind of circuit so that puppy gets wicked hot powering the nema 17.

I also got my Arduino and my RAMPS shield.

I did a couple experiments and got the Arduino to drive the motor. I didn't make a movie because it would be redundant as I've already done the same thing a couple times with gate logic and now I've to done it programmatically. I have to say I found the Arduino IDE pleasant and easy to use and set up. I read about some people complaining about the non brand name Arduinos giving a problem because the serial chip is a cheap CH340G. Even the ebay seller sent me a message reminding me to download the drivers for it which I did. Windows 7 found and installed the drivers by itself. The IDE was able to communicate with it and install the firmware(Marlin). The printer interface software also was able to talk to the firmware just fine. It remains to be see if I will have a problem in the future and if I do then I'll pay the extra 3 bucks for a real Arduino Atmega 2560 and demote this one some future project.

I added some more wood to my frame today so it's starting to look like it will be able do something soon:


I found this scanner in my attic that is so old it has a parallel plug. I will be dismantling it gleefully:


So I have gotten the electronics and the motors. I have also ordered the heated bed for which I paid $7.49.


I have decided to go with a bowden style feeder(which is used in delta printers) so I ordered the printed parts and hardware for it for $7.50.

I'm watching a j-head and an extruder gear.

This is what my work space looks like right now and I thus far spent $83.61:

A menacing looking vine grown on my phone from an algorithm I wrote for my next android app:  Here is the same algorithm with branches, texture, and leaves! I drew the leaves in Microsoft Paint, but the bark is real bark from a picture edited in Gimp for the shadow, seamlessness, and color(And you can't see if from here but the bark of that tree was covered in cicadas). Note the draw function knows when to 180 the shadow in the right direction so shadows aren't on the top of the branches. Not all of the trees look this good. Many are scraggly or unbalanced. Meh, it's a work in progress! YOU HEARD IT HERE FIRST! Got the gameplay mapped out. You will grow your tree from a seed and care for it and shape it to your whim using real(virtually) bonsai techniques. Watering and feeding schedules will be determined based on seasons and whether or not the tree is in training(stress) and health, etc Most recent emanation:  Whew! The ...

I think I have 200 accounts scattered all over the internet including 10 or so forums, 3 facebook accounts, a twitter account, google plus account, like 10 emails, 50 places I have ordered from- on and on! Why not add a sqeeqee account? I am not going to say that I am too lazy(as it is en vogue to say so) to check it out because I am not. I just have other priorities. Such as writing about something I am not going to research and know nothing about. Now THAT is important! That being said, I know mostly nothing about Sqeeqee.com. What I do know is that it is yet another social network that seems to be an amalgam of facebooklike features and ebaylike features and several others I am unaware of. I found it as the result of my marketing efforts for FlaTank and joined up. The appeal that it has for me is that it is still in beta testing. I am still seeing php errors in the ranking box sometimes and the claim to be 99% error free at this point. Usually stuff like this escapes me unti...

Tonite, I modified a few reset buttons(dpst) from old computers from normally open to normally closed. Those switches work nicely because they come with the Dupont plugs that fit my RAMPS shield. They are going to be used as end stops(currently I'm just using jumpers) The end stops are needed to establish an origin in the Cartesian geometry the printer uses to to determine where to put plastic. It won't be to long before I can start calibrating and then I can run the slicer program. Before I do that, I'm going to move the gantry back a couple inches because in my lack of planning(true intp), the build bed doesn't get enough travel under where the j head is going to traverse. I get the slicer dealie running, that'll be a cool video! Imma have to find some nice funky music for it. I know I didn't mention I was going to do this but hopefully I can put together the protection circuit for my sound-card oscilloscope this weekend. I've wanted an o...
