Troubleshoot: Unleveled Bot DrawingUpdated a day ago

If your Bot’s drawings appear tilted or uneven—like the marker touches one side of the paper but not the other—use this guide to resolve the issue.

Primary Causes & Fixes

1. Pen Is Dry or Worn Out

   • The marker might no longer produce consistent ink. Try replacing it with a new one and test again.

2. Table Not Leveled

   • Ensure the surface where the Bot is drawing is flat and stable.

   • Use a spirit level to verify.

3. Bot Not Properly Seated

   • Remove the Bot from the paper holder.

   • Clean the paper holder base and the Bot’s bottom to remove any debris.

   • Reseat the Bot firmly and ensure it sits flush with the surface.

4. Bot Firmware or Calibration Issue

   • May require a firmware update or factory reset (see below).

At an Event? Quick Workaround

If you're on-site and can't reset the Bot immediately:

• Use Z+ Calibration Compensation:

  1. Perform normal pen calibration using Z+.

  2. Once the pen touches the paper, press Z+ +1.0 four times (or more if needed).

  3. This pushes the pen slightly deeper, helping compensate for minor unleveled surfaces.

  4. This often fixes the issue until a full recalibration/reset can be done.

Factory Reset + Home Recalibration Steps

1. Disconnect Bot from power and close the software.

2. Reconnect Bot to power and reopen the software.

3. Open the Terminal in the software:

   • Type: M502 → Send (Factory Reset)

   • Type: M500 → Send (Save Settings)

4. Type: M18 → Send (Disengages motors)

5. Manually push the arm back and up, ensuring it is centered.

6. Type: M889 → Send (Home Position Save)

7. Type: M1112 → Send (Return arm to Home automatically)

8. Recalibrate pen height.

9. Test the drawing.
