First print

Postby Nimikins » 2013-Jul-Sat-01-Jul

Well, 32 hours after it arrived on my doorstep, I have a fully assembled printer. Most of the time was taken in staining and sealing. Only about 7 hours was actual assembly. First print using the setting out of the getting started guide, 1.75 mm PLA with brass 5/16 rods and a cork insulator on blue painters tape.

At almost exactly 1 in cubed, I'm happy.

After reading about the troubles you had staining birch I did some research. I did a pre treat followed by a second sand and an oil based stain. Then I did a very light coat of wipe on poly followed by a spray matte. I like your GO though. Much more steam punk than my driftwood. :)

How do you like those couplers, I've heard they can be a little too springy. Ive been debating getting spider couplers as they are about the same price.

They are VERY springy, I can bend the rods at a 45 degree angle. I never used the wood couplers, so I can't compare, but I'm on my seventh print with no issues with banding. In fact after a nozzle jam, and the printer refusing to print, the only problem I've had is taking a chisel to the abs because it sticks so hard to the aluminum build plate. At 1/4 in it takes forever to heat up, but it has a lot of thermal mass. I printed a 5 in wide plate for an electronics cover 2 mm thick with no warping. The other thing is I have to finish calibrating, the cube came out almost exactly 1in cubed, but I printed a hopper funnel for my filastruder, and it ended up about an 1/8 too small for the pipe. I just cracked it and let pressure hold it on.

Had a few good prints (and a couple false starts) but then ran into a problem. I started a 5 hour print and walked away for an hour or so. When I came back there was a HUGE blob inside the red sleeve that was no longer on the extruder. Ok, so I clean it up, and then try the print again. Suddenly I am having travel issues in the x direction. On the far right it is stopping for just a fraction of a second and coming back on the left it isn't going as far right traveling back. I have a class this morning, but will troubleshoot and add more pics later. Just wanted to post my first official blob.

Ok, well after perusing the forums, it was a 10 sec fix, my x pulley set screw was loose. A night of printing wasted because of a loose screw :( sigh, problem solved though! :)
