    • Thank you for the reply. I tried that without results. What were your slicer settings for the pistons? Im using an extruder width of .400 (to match my nozzle) and a layer hight of .120 (multiple of the above .4). if i print with less than 3 vertical walls, its too brittle and breaks apart easily, while it does fit.

  • I am printing the InMoov torso and after following several other projects I am wondering how hard it would be to replace the 3D Printed Piston parts with Linear Actuators? It looks like they may be a bit more expensive but may be a bit more rugged. Do you all think that a Linear Actuator with 4 inches of travel would be able to replace all of the…[Read more]

    • i have stated this already on another thread – linear actuators will add weight and need room. question is also how speed will compare with Gael’s solution. believe me – you look at a lot of time required to redesigning the bot. do not underestimate time to design and print modified parts. I did not encounter mechanical issues with the current…[Read more]
