First Print, almost great!

Postby Tdeagan » 2013-Feb-Mon-12-Feb

New Printrbot Plus. 32 hours build time from box opening to this print (a couple of hideously failed attempts preceded this.)

After many hours of extruder grief, I managed to get a legit first print. Getting the filament to feed without stripping was a mess and I had to do a _lot_ of hob bolt cleaning.

Here's the model I started with (simple maker-mark stamp I've made for my leather working):

Here's the print:

There is some gapping between the perimeter and infill and a weird jog that is on the outside top right (and seems to be on the outside top right of the internal circle.)

The bottom layer is a bit flatter than I'd like.

Lots of tuning awaits me!

Tuning largely complete!
Primary problem was that my X axis motor mounting was trapezoidal rather than square. See Step 142 in the PB+ assembly instructions (sorry, system won't let me add an actual link offsite). The bolt attaching 220 to 232 needed a nut INSIDE to keep the belt from pulling the motor into the frame, rather than OUTSIDE. My motor was rubbing against the frame and causing the equivalent response to backlash.
