Hello all,
Hope all is well with everyone on this always incredible forum!
I recently aquired a Stratasys Dimension SST768 for very cheap. The printer is currently non functioning, and i fear it may need a new 186 board ($$$$$$)
If this is the case, I plan on retrofitting it with a ramps board
I have built many of my own printers before, and have the theory of how to do everything, including the heated build chamber, down.
The one thing that I am stumped on however, is the extruder motors. They are coreless DC servo motors, with 6 wires. I know there is a project on using servos for closed loop control through the step and dir signals from the arduino mega, and I plan on implementing this to drive the extruder motors. However, I do not know what the color codes on the wires are. In the closed loop system, the guy is using a 4 wire system, 2 wires for power, and 2 wires for optical feedback. I believe this motor's encoder runs on a hall effect sensor, and I believe I can make it work with that system once I know the pinout.
Any help is greatly appreciated!
I do have a good fluke DMM to test with. I know the motor runs on 12V, which is perfect! Other than that, I am stumped!
The reasoning for this, is to get the printer running with as little modification as possible. I only want to print ABS/HIPS with it.
Thanks again to this great forum!
