50 micron Printing Problems

Okay so I am using a custom machine thats running an Azteeg X5 mini using 1/32 micro stepping for the X and Y axes and 1/16 for the extruder and Z axes. At .2 mm layer heights everything prints just fine. But when I go to print at 50 microns, the filament doesnt even come out of the nozzle hardly. Whats going on here? How can I fix this?

Well there's a big difference between printing at 0.2mm and printing at 0.05mm. Many machines aren't even capable of printing at that low of a layer height.

Best I've done to date, repeatably and reliably is 0.08mm with a .25mm nozzle. It does take time to get the printer dialed in, but the results are great.
- 1" tall rook with spiral staircase and double helix inside.
- 3" diameter 1.5" tall. printed in two halves. ABS. Approx. 34 hrs print time.

Nice! What printer is it? What plastic were you using?

Also, how did you design the rook, I mean, I know a way to do it in inventor, but the way I'd to it would talk forever, having to but each rectangle out one at a time for the steps...
I imagine there is some easier way...

The printer is a Lulzbot TAZ. It's the Kittaz (unfortunately they have discontinued) that I have upgraded to the specs of their current mainline version, the TAZ 5. I also changed the stock nozzle to a .25 nozzle, and built an enclosure for it. The plastic used for those parts are ABS (natural) from eSun.
I bought the printer just over a year ago, but it was put on the backburner during some house remodeling. I got to really start working and learning with it in mid August. I am very happy with it's performance. I had one problem at the start of Nov. with the fan in the power supply starting to fail. I contacted Lulzbot, and even though my warranty had expired last Dec., they sent me an updated new power supply. They have great customer service and a great forum community too.
I am currently trying to print the wheel using a wax filament from MachinableWax.com, with an eye toward having the part cast in aluminum.
