UM2 starts shipping with Olsson block included!

Recommended Posts

I'm loving it! the quality is much better and i get my print quicker!! more internal stringing but better overhangs and overall quality for some reason, i may try 0.5 instead of 0.6 as i see some non important anomalies. i had a feeing it was just extruder speed related rather than diameter related as all the surfaces are perfectly smooth. Seeing as the um2+ had heavier objects compared to the um2, is it overextruding compared to the um2?

So basically if you see this, you are over-extruding, definitely better than under-extruding!!!

I'm now very happy with my upgrade!

EDIT: the flat surface lines under closer inspection indeed do not connect as ultijan said, but walls connect, so for organic stuf, this is a fantastic time saver, but for flat horizntal stuff no good if you want it perfect. Is there a way of increasing the flow in cura to increase it a touch as i dont like using that setting on the pinter? i only adjust temps live, flow and speed i stay away from ad they make weird noises when you change them.

Here is a blue over-extruded one, exactly the same settings as the red, 0.4 nozzle with 0.6 selected from cura. dutch orange is more runny, meaning it doesnt handle overhangs very well but surface looks good am currently printing slightly lower and dropped it too low at one point so i got some under-extrusion, but that was experimenting to see how low i could go, but lower temps with runny filament doesnt help that much from what i see...

ill post a finished pic for comparisons, but now i think i don't even need the new fan shroud for the ob, this one appears to do the job just fine with minor adjustments to the shape.

Here are the finished OB print tests. I lowered the temps too much at the start of the dutch orange, hence the underextruded layer which broke off when I was taking it from the plate. other than that I think the ob is fine for my purposes, I still have one more delicate test but so far so good.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
