Looks like my brainwave died.. extruder motor is no longer running, i've tried a half dozen other steppers and none of them turn, occasionally when attempting to extrude the z-axis starts moving randomly... I am done messing with it to try and get it to work again. So taking this opportunity to do a massive upgrade. Have the FSR kit in hand(ultibots), ordered the Azteeg mini and viki2 (http://www.panucatt.com/azteeg_X5_mini_reprap_3d_printer_controller_p/ax5mini.htm), ordered a set of magnetic carriages and end effector from aliexpress (https://www.aliexpress.com/store/pr...-kit-for-Delta-kossel/718699_32594459530.html) and got a new version of the E3dV6.1 (catridge thermistor) on order direct from e3d along with a titan extruder. Will provide some pictures and progress as I go. following in the footsteps of @grainiac and see how things go from there, the kossel pro was supposed to be my first 3dprinter but I have moved onto a i3 prusa version so i can print parts to fix the kossel. really hoping to get this bad boy going and running in tip top shape so i can stop messing with shimming and leveling a bed.
