How has it been working?
I notice in the pictures you used a 42mm NEMA17 stepper. I've seen some discussions where people have been going with a lighter 20mm or 24mm NEMA17 stepper to save weight on the moving carriage. I've been toying on doing this on my XL300 now that I'm just building a whole new set of plastic parts for it.

I've been happily printing using 1.75mm abs/pla/petg with a titan with 20mm nema 17, no issues so far. Will give it a really good test on my new delta which should print at much higher speeds than my kossel mini (with ramps/arduino). The weight saving is large and the 3:1 gearing allows for fast retractions compared to the fractionally lighter geared nema 14/11 combinations some other extruders are using. I have to run this motor with enough current that it is warm to touch but its still only around 45 deg C. Main reason for buying one really, its light and its good.

So the one I'm using at the moment is this one (140g/13Ncm):

I bought the same one for my new printer as it seems to work pretty well.
I don't think you can get more torque in this size, I'd avoid the 0.9 deg type for this application also.
You can go up to a 25mm motor at 180g and 18 Ncm torque. So 38% more torque for 28% more mass, definitely would my next choice if the 20mm one can't perform at higher speeds. But accuracy might suffer at higher speeds with more mass.
