Well, I’ve never gone lower than 0.1mm, and have been satisfied with that. 0.005 seems pretty thin. I have done some good looking prints at 0.35mm as well…
Since you’re in the Lulzbot Cura, how about just trying a test print with one of the quick-print profiles it comes with? If you can print a little calibration cube or the rocktopus, you at least know you can run the machine.
If that .005 is inches (just a shade under .013mm), it’s do-able. Not too far from the Cura High Detail quickprint settings for PLA.
If that is .005mm, I doubt you are going to see it happen on one of these printers. I don’t think this technology works to print .0002" (two ten thousandths of an inch). You need to exercise care with a micrometer to even measure that thickness. If you really were measuring in mm, are you sure you didn’t slip a decimal point?
Yeah, it doesn’t work at that fine a level. Just seems to crash the app and then the machine freezes. Here is where mine stopped.
FlashInPan, I’m curious what you ever found out about the Control button not appearing in Cura on your Mac.
I see Aleph Objects released a letter describing the problem. I’ve still had no problmes using Cura with my 2015 Mac Powerbook or my wife’s several year old iMac (both running OS X El Cap, 10.11.3).
Well, the control button just doesn’t seem to show up. In its stead is a button to save the code.
I just got my printer up and running over the weekend and had the exact same problem with my Mac running the most current version of OS X. I followed the instructions as listed earlier in the thread of:
boot mac into recovery mode (command+r). hold it down until you see the mouse cursor
open utilities, go to terminal mode
type: csrutil status
probably says enabled
type: csrutil disable
reboot
It has worked without a problem ever since. As an aside, this is the second issue I have had with this most recent version of OS X that required csrutil to be disabled to see a device. I was unable to recognize and program a Logitech Harmony Remote without doing this. So it is not an isolated thing.
Hope that helps.

I am TOTALLY going to try that! Thanks for the suggestion.
Also, ironically, I designed the UI for the Harmony Remote 
That TOTALLY worked! 
So major problem ONE solved, thanks for posting that fix. I hope others can benefit by that too.
My only other problem is that when I print from my Mac, my models come out like blobs. Somehow, I think that will be easier to solve with more research. See photo: Printing Blobs. Somebody Please Save me!
Thanks again!
Hey all,
As an update on this topic: I got a Taz 5 a week ago (and still have yet to print anything). I had 2 issues out of the box, left Z axis binding, that I have mostly resolved, and the non-connect issue between CURA and Mac that’s discussed in this thread. I have a MacBook Pro and am running El Capitan 10.11.6. Tried all of the Aleph suggestions, cable, port, down grading to CURA 17. I also just tried the disable and reboot as some others have tried with success. Still no connect/control button. I hate to go through yet more hassle of downgrading to Yosemite, not looking good though.
Possibly a stupid question, but you are loading an STL file to print, aren’t you? The control button does not show unless a file is loaded.
Not a stupid question at all! No, I have not tried this. This is a new printer and I haven’t been able to go through the motions of moving the axis’ and leveling the bed utilizing CURA (I haven’t ever used CURA). So I will give that a try. Am working the next three days, so Ill give it a shot on Friday.
Thanks for the idea… would be nuts if it actually works.
Yeah, you can’t get to any of that control stuff in Cura unless you load a file onto the platform.
That was it. Okay, totally my bad. the instructions that come with the printer have loading a file as one of the steps and I went straight for the calibration sequence. As soon as I loaded the “rocktopus,” the control button magically appeared. Thanks for speaking up John Mc and not overlooking the idiot factor. 
It happens to everyone sooner or later.
