Stacker S4

  • Minimal 2 wall lines.
  • Check Z Seam Alignment (under Shell). Random might be nicest for objects without corners.
  • Is there enough filament?
  • Check the fan blip at the start.

Parking location for 'pause at height' postprocessor script:
X = 500
Y = 366

When you suspect that filament has crept up the hot end, pushing the Bowden tube up, clean the nozzle with a cold pull when the Bowden tube has been removed.

  1. disconnect the cable of the heater block
  2. unscrew the nozzle with the heater block attached
  3. reattach the heater block cable. The nozzle is suspended on this cable now.
  4. heat up the nozzle to 200°C
  5. Hold the nozzle with pliers under the threads. Manually extrude some 2,85mm filament (The Stacker normally works with 1.75mm filament, but this way the filament doesn't break as easily)
  6. set the target temperature at 0°C. The printer is now cooling down.
  7. When the temperature reaches 92°C, grip the nozzle on with pliers on the part above the threads. Position it against the metal frame of the printer so the force of pulling out the filament will go into the frame of the printer.
  8. With a quick pull, remove the filament from the nozzle.
  9. If the result is not good, repeat the cold pull again

Colorfabb: For us changing the EEPROM speeds worked well. I would suggest for both values 9mm/s. (For the Stacker at Formlab, this didn't fully get rid of the whine). Of course good maintenance is very important, so lubricating the linear rails is important to prevent unnecessary friction and rust.
