===== Print on fabric =====
  * Get a stretchy kind of fabric. Lycra seems to work well. <wrap hi>More details are coming</wrap>
  * Create a vector drawing with max dimensions of 25x25cm. 
    * A combination of lines and gaps seem to work well.
    * Fully closed shapes won't change the curvature of the fabric after printing.
    * Export as SVG file
  * Make a 3D model from the vector file
    * Use Fusion 360 or Blender for ex.
    * extrude the shapes vertically 0.3mm
  * Slice in Cura
    * If the drawing is only lines, try minimizing infill and up the amount of walls for cleaner lines.
    * slow down the initial layer speed to 8mm/sec
    * Export the G-code
  * Post process the G-code
    * Open the gcode in a text editor and add this '[[http://www.formlab.schoolofarts.be/instructions/doku.php?id=lulzbot_taz_6:lulzbot_taz_6#pause_before_print|pause before print]]' snippet to it.
    * Save and put on an SD card
  * Print
    * Change filament
    * Run the G-code (Menu item ''print from SD'')
    * When the print head moves up and the printer pauzes, stretch the fabric over the build plate
      * Clamp the fabric with small clamps around the bed. <wrap hi> Be careful to not move the print bed. The motors are de-energised and the bed can accidentally be moved by hand. We should look for a fix.</wrap>
      * Check that the fabric or clamps won't bump into things or trigger the limit switches.
      * When ready, click ''resume''
      * While the printer head moves down, manually push some filament into the print head to prime the nozzle. Put a scrap piece of paper under the nozzle to catch any molten plastic that squirts out.
      * Lock the feeder into place just before the printer starts
      * Go into ''Tune > Z-offset'' to be ready to change the distance of the nozzle to the fabric if the print won't adhere properly.

===== Troubleshooting =====
  * The printer underextrudes after ±10 - 15 minutes.

==== Every 2 months ====
  * Check your belt tension
  * Wipe down the smooth rods (no lubrication)
  * Blow out the fan/control box while powered down

==== Every 6 months ====
  * Lubricate Z-lead screw

==== Yearly ====

  * Check the set screws on the stepper motor pulleys and the small gear on the extruder, tighten if necessary. Use of a mild thread locking compound is acceptable.
  * Examine the threaded rod couplers. TAZ users should make sure the hose clamps are tight.
  * Verify that any frame screws are tight.
  * Check for software updates. Update Cura LulzBot Edition at [[https://www.lulzbot.com/cura|LulzBot.com/Cura]]. Slic3r can be found at [[https://www.slic3r.org/|Slicer.org]] and Printrun can be found at [[https://github.com/kliment/Printrun|Github.com/Kliment/Printrun]].
