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 bed frame stands *optional*
- Part number [11032] for the left bed bed frame stand
- Part number [11033] for the right bed frame stand)
- 8mm wrench
- Allen key set
Reseating Threaded Rods
In some sever cases of the bed becoming unlevel, you may find that your threaded rods have come out of the lower bearing block. To fix this, please perform the following steps:
-
On the side of the frame with the lead screw sticking out, manually push the Z-axis motor pulley belt at the base of the threaded rod so the threaded rod rotates clockwise when viewed from above. Do this until the rod moves downwards and can reseat into the hole of the bottom bearing. You may need to adjust the tension on the Z motor belt to get the rod to be able to move into the hole which can be done using the steps in this video: Tensioning the Z-Axis Belts. Make sure to retension the belt before continuing on

Written Instructions:
Option 1: Using Bed Frame Stands
1. The four included bed frame stands (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. Figure out which side of the bed frame needs to move upwards to become level with the other, then manually push that side's Z-axis motor pulley belt at the base of the threaded rod so the threaded rod rotates clockwise when viewed from above. This will cause that side of the bed to move upwards. Rotate this until the sides are close to level.
4. Apply red grease to the lead screw anywhere that is missing grease.
5. Use the Viki to move the Z-axis to drop the bed down to just above the bed frame stands. Please take this process slowly, and stop if there is any seizing of the bed frame nuts to the threaded rod or any noises. Increment downwards slowly to avoid running into the stands. Stop when you are about 1 mm away from the stands.
6. Once the bed frame is about 1mm from the stands, use the Viki to disable the steppers (Prepare > Disable Stepper, the manually rotate the belts until each side of the bed frame is just touching the stands.
7. Be prepared to hit the Gigabot power switch, then press home Z axis. Stop it at any moment any binding occurs or you hear any noises. If so, contact support@re3d.org for further instruction. If the bed is moving well, continue to let hit home until it is about 10cm from the nozzles as your Gigabot still needs to be recalibrated.
10. Perform Bed Leveling steps, and set the Z-axis home position.
Option 2: Without using Bed Frame Stands
1. Figure out which side of the bed frame needs to move upwards to become level with the other, then manually push that side's Z-axis motor pulley belt at the base of the threaded rod so the threaded rod rotates clockwise when viewed from above. This will cause that side of the bed to move upwards. Rotate this until the sides are close to level.
2. Apply red grease to the lead screw anywhere that is missing grease.
3. Be prepared to hit the Gigabot power switch, then home the Z axis. Stop it at any moment any binding occurs or you hear any noises. If so, contact support@re3d.org for further instruction. If the bed is moving well, continue to let hit home until it is about 10cm from the nozzles as your Gigabot still needs to be recalibrated.
4. Using precise calipers 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.
