Step by Step Calibration
Step One:
Manually, find the highest side of the plate adjust using a flat head screw driver, raise or lower the side until the plate is touching the nozzle tip on all four sides and then the center.
Use a sheet of paper and slide it under the nozzle on one side, if the paper is too loose or too tight, adjust the plate using a screw driver until the sheet of paper can slide with resistance under the nozzle tip. Once successfully done, continue the steps for the rest of the sides of the plate and the center. Then home the Z-axis, from there manual calibration is complete. +

Step Two: (After your plate is manually leveled)
Open MatterControl (if you do not have MatterControl on your personal computer download here: http://www.mattercontrol.com/#jumpMatterControlDownloads
After you have completed the download process of MatterControl, open the software.
Click on CONFIGURATION at the top right corner.
You will then see Automatic Calibration, Automatic Print Leveling should already be enabled
If not click enable.
 
Step Three:
next to Disable click on Configure.
From there you will be prompt to the MatterControl- Print Leveling Wizard
You will need:
1). A sheet of paper
2). Flat head screw driver
3). Make sure your plate and nozzle tip are clean from debris.
4). Nozzle temperature should be turned on.
This process will take roughly 3 minutes to complete.

From there you will be prompt to follow the easy leveling steps.
If you come across the MatterControl-Alert:
"Warning Moving Too Low.You cannot move any lower. This position on your bed is too low for the extruder to reach.
You need to raise your bed, or adjust your limits to allow the extruder to go lower."

Not to worry, simply go back to the last step and try again.

If the alert still prompts, simply adjust your Home sensor, using the thumb screws to adjust the height and continue with the last step.
Once the Automatic Leveling is complete, you are ready to use your 3D Stuffmaker desktop printer.
It is important to be sure that the extruder assembly is properly calibrated to ensure proper filament feeding and performance

To determine if calibration is needed, remove all filament and rotate the large extruder gear back and forth by hand using a smooth motion.  The gear mesh should feel very smooth and consistent with no excess play or binding whatsoever at any point in its rotation.  If excess play or binding is felt, use the following procedure to adjust: 

STEP 1
- Adjust Large Gear
  • With filament removed, ensure that there is no wobble in large gear.  if there is any wobble, loosen locking nut and hand tighten gear on threaded shaft.
  • Re-tighten locking nut and check for smooth movement without any resistance.
STEP 2 - Adjust Gear Mesh
  • Loosen (4) four screws on extruder motor to allow it to slide freely.   Insert 4/10" in spacer between the gearing teeth of small and large gears and sandwich together.  The 4/10 inch spacer is about equivalent to 4 sheets of paper or four layers of the surface protection tape.
  • While applying pressure with motor to large gear, tighten fasteners to hold in place.
  • Check for smooth, non-binding movement of gears.
STEP 3 - Adjust Extruder Clutch
  • With filament loaded and closing latch secured in the vertical position, apply pressure by hand to the latch assembly as shown.
  • While applying pressure, tighten the adjustment thumb screw by hand until finger tight and then back the screw off (1) turn.
  • Close the latch and verify smooth feeding and operation.





Cleaning

◦Clean outer smooth surfaces with a clean moistened microfiber cloth.
◦For smooth and threaded rods, use a disposable lint free cloth to remove any accumulated dust or debris.

Lubrication

◦Clean and lubricate rods after approximately 50 hours of use or if any squeaks are heard in movement.
◦For smooth rods, only use clear silicone grease and apply a light coating to rods of the X, Y, and Z axis.
◦For threaded Z-axis rods, apply a lithium or graphite based grease for wear, heat and corrosion resistance.

Belt Tensioning

◦Belts should have a maximum deflection when measured at the pulley bearing of between 13 and 15mm.
Also, when strumming the belt, it should resonate for no longer than 1 second.

Extruder Adjustments
◦Extruder gears should move smoothly by hand with no binding during rotation.
◦If play is detected in gear mesh, follow calibration procedure.
