Mini-Mug and Z-stage crank
The mini-mug came out looking fantastic. The Z-stage crank was actually my third print. The handle got a little … blobby so you can see where I sanded it down.

I was having some trouble getting my rafts to stick to the build platform until I did the following:
- Switched to the acrylic build base (which I promptly pock-marked with a hot extruder)
- Changed the Skeinforge raft settings to those suggested on the Thingiverse blog
If you’re having raft trouble, do both of the above and don’t look back.

Calibration is proving to be a relatively slow process. As you can see from my prior post, my prints are drifting towards the back of the MakerBot. This appears to be due to either improper tension, the power being set too low for the Y stepper motor, and/or the Y axis rods not being smooth/oiled/straight enough. Given that the first few layers are spot on, I suspect it is a stepper board power issue. The Y axis motor is easily the first quietest of the three axes. As the X axis motor is the nosiest, I could probably dial it back without an effect on performance.
To do for tonight:
- In the hopes of diminishing the Y axis drift problem
- Oil the Y (and X and Z) axis rods
- Check the Y (and X) axis slides
- Dial up the Y axis power by turning the potentiometer on the Y axis stepper board clockwise
- In the hopes of diminishing operational noise
- Dial down the X axis motor slightly
- Dial down the Z axis motor slightly
