I have my hands on a i3v 12in from makerfarm. Have had it for about 2 weeks. Been doing tweaking this entire time. I'm using Simplify3d.

I've done thin wall test, and 1cm cubes, and such. But I have restarted the process.

What I've done so far.

Calibrate steps on firmware to match real distance traveled with calipers.
Leveled build plate.
Prints stick to first layers well.
Printed a thin wall cube to obtain desired extrusion width to match settings, 0.4, resulting in an extruder multiplier of .75
Printed thin wall towers to obtain visibly looking optimum printing temperature. Resulting in 217 C

With that, I thought I give a shot and print out a Ctrl alt Print from thingiverse.

I used a default print speed of 50mm/sec
X/Y Movment speed 125mm/sec
Temp 217 C
Bed 60C
Retraction Distance 1mm
Retraction Speed 1800mm/min 30mm/sec

Looking at the machine Print, I thought it was moving to fast in the detailed parts. Jumping all over the place in a smale area. I wan't to to get rid of that behavior. Need to take a look at my slicer.
