Good work bobc! You are our savior .. Long live open source. I decided to create low level stepper motor H-bridges soon, wish to use RODOS operating system (it's like RTOS but C++). The reason is I don't need microstepping and want to save the current sensing so that it's a ultra low cost and easy solution. (hopefully). If I fail I will fall back to your, Michal's and all the other contributerby Radagast - Developers
Originally my goal was to keep everything fixed besides the rotational movement of the multi-resin container/raft and the 3D-model to be printed fixture. I wanted to use dudesome's idea to move the fixture to the bottom by putting it in a container within the lower resin/water tank in the saltwater so that by letting water drop out of this container (where the fixture floats upon) the fixture wouby Radagast - Polar Machines, SCARA, Robot Arms
So creating a non-vacuum chamber big enough that the nearest metal/conductive object is the metal powder can also work? Do you plan to use the double vacuum now - just like you stated: high vacuum at the electron beam source/gun and low vacuum in the main chamber? I heard that a laser 3D printer needs vacuum too so it's good we chose the electron beam path. Couldn't we create a moving electronby Radagast - MetalicaRap
