It’s an angry robot.

2016_feb_SXY_02-1Despite working hinges (!) this little one became angry when the white ABS chose to warp intensivly on his chin. Look at it – i also would get mad with that chin. This one was printed in 0.15mm, 30mm/s. Another one @0.2mm, 24mm/s  is almost ready, but i don’t think it will get much better. 20116_feb_SXY_01
As you can see, one can still see X because it still is the old one. Btw. I decided to buy a new Z instead of building one by myself. It feels kind of cheaper that way. 🙂

accuracy…

2016_jan_SXY_01Sometimes you just want to print something to see if the changes you made on your maschine made it better or worse. A few days ago i installed new step-sticks for X and Y, the ones with 1/32 microstepping. Although the stepps/mm doubled, my Ramps has no problems driving SXY with 400mm/s on rapid-moves. The sound is a bit smoother but there is still room for improvement…

The print on the picture above is this robot from thingiverse. It has moving arms, hands, legs and feet. The support you see is to print the arms with ~30° overhang. The gaps between the moving parts are ~0.33mm. I am not shure if it is a good idea to print it with ABS…
