Got the Z axis going

Finally got the Z axis working, looks like 2 stepper drivers i got are busted.  Either defective or I fried them, one is completely silent, the other gives the motors a twitch with gets more violent with more current.
Made a simple GUI to control the motors.  The motion is quite slow probably due to throughput limitations of UBW, i may switch the steppers from from 1/16th to 1/8th or even a 4th and go to more toothy pulleys.

Next thing to mount and test the end stops.

Exruder meets the chassis






To my surprise i found out that pulleys have different number of teeth, x and Z axis use pulleys with 8 teeth. Extruder uses one with 12, and my sets includes couple more 10 toothed pulleys just to make things more confusing. I could probably switch to those if i want little bit more speed.
Wires are too short for the Y axis motors, and they need extension. Same with extruder motor. Nothing that can't be fixed with little solder.

Body assembly




The body is coming together nicely. I'm giving up on the idea of using salvaged steppers and belts. Time to start ordering electronics...
