Ord bot update — First axis movement

2013-04-26 19.36.24

So I finally made some time late at night to work on my ord bot.  First thing I did was try to true up some of the brackets, make sure everything is straight and tight.

Next I went ahead and soldered the stepper headers onto the azteeg x3, I decided this look was cleaner than going with the screw terminal approach.

Finally it was time to wire up the power supply.  I just chopped up an old IEC cable and screwed the terminals down.

A quick power on test of the azteeg.

A little bit of wire twisting, some electrical tape and I loaded up Marlin firmware sketch, tweaked the values a little to match the azteeg x3.  From here I ran into an issue where the board went into failsafe block mode because I don’t have any of the thermocouples hooked up it thought it was frying its self, so I disabled those in the firmware.  Try #2, I was getting steps, but not good steps.  I adjusted the stepper current using a meter and a small screwdriver on the pots, but still odd movement.  I finally realized that I hadn’t put any jumpers on the microstepping selector and was doing full steps.  After setting that it was moving like butter!
Here is a video of me just playing with the motor back and forth.

Ord Bot build update and qu-bd extruder build issues

2013-04-13 01.54.10I got some parts in for my ORD BOT 3d printer build and I spent a good day putting it together.  Well I didn’t make as much progress as I anticipated and sadly had a pretty frustrating time, mostly with the QU-BD extruder build.  While it should have been fairly straight forward let me start off by pointing out the build instruction flaws.

The ord bot build has begun!

2013-03-21 03.10.17I was greeted with a package today containing some of the parts for my 3d printer (ord boy hadron).  So late last night I spent about 6 hours putting the frame together.  I can’t say the assembly documentation was well spelled out, it was just barely enough to get it done.  And even then I know I put some parts on wrong.  I’m not worried about it though I just wanted to roughly put it together, as I have no electronics other than steppers at the moment.  So I’m still waiting on the extruder, heat bed, controller.  I didn’t bother running wires or aligning the rails.  It moves pretty good but I need to take the gantry off and flip the mounting bracket for the extruder, also some how I have the stepper on the wrong side for the y axis even though it shouldn’t matter.  I feel good about it, there were some annoying things like the front foot didn’t mount well. The holes in the aluminum weren’t tapped and the only tap I had was a cheap chinese one that didn’t work _at all_.

More 3D Printer parts ordered

I ordered a bunch of stuff from Panucatt Devices, namely the Azteeg X3 controller, Helios 200 Heat bed, and a viki lcd just for fun.  I also went with the dual extruders from QU-BD, despite what I’ve read on the internet.  There are a lot of unhappy people with this extruder, i’ll try it, and if it doesn’t work out i’ll pick up something else.  I still need a power supply, I’m not sure why people are moving away from using ATX power supplies, maybe for size?

Hexy the Hexapod build

 

2013-03-14 02.31.30I got my Hexy the hexapod kit from the kickstarter finally, maybe 6 months late.  Reasonable in kickstarter terms.  Anyhoo I decided to put it together last night.  The build process was pretty straight forward, however towards the end when you get into like mounting the battery pack / routing wires / etc things get a little sketchy.   I guess my biggest gripe right now would be with the power, I need to order some lithium/nimh cells or do a custom battery pack or something.  Alkalines aren’t goint to cut it.  I was a little sad not to have gotten much movement out of it.  I even hooked it up to my bench power supply but it maxxed it out at 3A and still just failed.
