Revision as of 18:43, 7 December 2010

  • The objective is to create a linear motion device that will calibrate a set array of scintillators using light pulses

Ideas

  • Printer disassembly and take-over of printer head linear motion through use of parallel port programming with C
  • Worm gear connected to DC motor with micro controller set up
  • Linear Rail system
  • Stepper Motor Belt System

Printer Disassembly

  • Disassembled printer casing
  • Installed cygwin on computer for C interface and read up on programming language C
  • Investigated Computer Numerical Control but found it was not useful for this application
  • Investigated serial port programming and the use of Printer Control Language on an HP printer
  ===Parallel Port Programming===
  • Interfacing directly to the printer proved very challenging
  • Unsuccessfully accessed printer
  • It seems one would need to write a driver to fully take over the printer in the way we desire

Worm Gear

  • Spinning a long grooved cylinder gear requires a lot of torque
  • Minimal support for head motion
  • DC motor with time steps is not as effective as stepper motor

Rail System

  • very costly
  • possibly too heavy duty for this application


Belt System

  • Stepper motor with micro controller stands stationary on one end and calibration device would be connected to a slide rail system for stability
  • We need to find something that is low cost but is accurate enough to be stopped at each fiber array block. This would call for a low pitch. One example I've found is as low as 8mm pitch with 200 teeth making a 1.6 meter timing belt. Because the intended light source for calibration is most likely going to have a wide range, 8mm is a fair sized step as the scintillators are 2mm each but grouped in blocks.
   === Motor ===
  • Need to locate a stepper motor to attach to one end of the pulley belt system
