Leveling the Bed Frame

Overview

When leveling the bed frame, you may opt to use bed rests or proceed without them. There are two sets of instructions outlining each method. 

Tools Needed: 

  • Four (4) included bed rests (optional)  
  • 8mm wrench
  • Allen key set 

Jump to: No Bed Rests

Option 1: Using Bed Rests

1. The four included bed rests (two shown below) will allow you to completely rest the bed on the bottom of your Gigabot frame to get it perfectly level.

2. Place the four bed rests in the bottom middle of the machine like those shown in the photos below:

3. Loosen the bolts on the sides of the bed side plates affixing the cross rails supporting the bed.

4. Tighten or loosen the bed leveling knobs until they are all the about 1/8 of an inch away from the top of the side plates as shown below:

5. Use the Viki to move the Z-axis to drop the bed down to just above the bed rests. Please take this process slowly to avoid running into the rests. Move to 500mm, and then gradually work toward the rests by 1mm increments.

6. Loosen the bolts in the middle of the side plates (shown below). **Caution: These might be difficult to undo, and once removed, the bed will drop down with great force.**

7. Once the bed is resting on the plastic supports, use the Viki and select "Prepare" > "Disable Steppers."

8. Manually move the Z-axis motor pulley belts (picture below) on both sides so that the holes on the nut bracket on the threaded rod realign with the bed plate.

9. Tighten the bolts again on both sides and raise the bed back up, but don't home the Z-axis yet. The bed might run into the nozzles, as your Gigabot needs to be recalibrated. 

10. Perform Bed Leveling steps, and set the Z-axis home position

Option 2: No Bed Rests

1. Loosen the bolts on the sides of the bed side plates affixing the cross rails supporting the bed.

2. Tighten or loosen the bed leveling knobs until they are all the about 1/8 of an inch away from the top of the side plates as shown below:

3, Using the Viki, select "Prepare" > "Disable Steppers."

4. Measure the distance between the side plate and the top of the Z rail upright on both the left and right side of the frame as shown below:

5. On one side of the frame, manually move the Z-axis motor pulley belt at the base of the threaded rod until the measured distances between the side plate and the Z-axis rail match.

6. Perform Bed Leveling steps, and set the Z-axis home position
