Nice! I am also working on a mini delta that uses the linear-rails-as-frame idea. But it's still in early stages

Well it can print, this was ABS at 0.3mm layer height, the mini hot end lays down filament nicely, its quite a sharp nozzle. This is about the 5th object I've printed. Started off with PLA but I don't really get on with it so now onto ABS.

ABS 0.2layers, no print fan at all.
Pretty pleased with this, it looks more overextruded in the photos than it is. I'd say the idea that small printers are easier to get good results from is not in any doubt for me. It took weeks of tuning to get my large printer to turn out a benchy like this.

Recently changed some things and have updated thingiverse.
-changed to Rich Cattells marlin which allows much more detailed calibration parameters to be used and now have perfect calibration, previously it was close but not quite right.Even the latest Marlin doesn't support this level of adjustment for deltas.
-changed the wiring arrangement using the xbox power supply to improve available power when everything is on.
Just printed this trio of Marvins, ABS, 0.2mm layers, barely any fan at all. The mini hotend is very good at fine details and overhangs. Now if only they could hurry up with the new nozzles they're promising, a 0.3 or 0.2mm nozzle might be able to print some very small things.

It's amazing how many parts of the printer get tested by this model. On the surface it looks easy. Getting it spot on perfect everywhere, however, is quite a challenge.
Much appreciated. Looking forward to it

Will try a 100 micron one this evening.
Much appreciated. Looking forward to it

Okay so 0.1mm is not my friend.
Curly overhangs on his "gentlemans area" the droopy filament in the eye socket and an eyebrow that looks like he got drunk and his mates decided to play a prank on him.
That being said maybe with a bit more intense and directed cooling which this printer lacks, or maybe try fewer perimeters, what do you think?
I also printed this one on the kossel XL at 60 microns, he's not that great but he is a 50% scale version.
I'm on a mission to show the UM3 that 60 microns is doable. Maybe with the mini hotend on the kossel XL or a 0.2mm nozzle?

0.3mm nozzle, 0.06mm layer height, cheap red ABS, directed cooling.
Still have that F!@#$%^ filament droop inside his right eye. Apart from that (and a bit of crud that fell off the nozzle when printing the keyring loop) this one looks OK to me.

Re: DemonDeltaMicro printer February 07, 2017 01:15AM |
Wow, 50% scale and 0.06mm layer height is tricky. This is only my second print at 0.06mm (first one is the red one above). Obviously needs work. 50% scale is tiiiiinnnnyyyy.

Here's a fan duct that should be a good starting point for that hotend, it clips onto the existing mounts for the fan, and should give you 3mm clearance between the part and the duct.

So good shout on the copper fill PLA. Definitely better at 0.1mm. Barely printed any PLA on this machine so a bit of stringing in places. Eyebrows and eye sockets still a challenge.
But where I'm gaining as its heavy and doesn't curl on overhangs, I am losing at the corners of the eyebrows as the first overhanging layer droops. I reckon I could knock the extruder temp down a bit more. That fan I found on aliexpress $10 plus $8.99 shipping so probably worth getting a couple to save on postage.
