How to use the g-code files:

1. Initial Setup with Nozzle:

   • The right nozzle will move directly above the first bed tramming point, and the heat bed will raise until it’s near the nozzle.
   • Slide a piece of paper between the nozzle and the bed. Adjust the bed screw until you feel slight resistance when moving the paper.
   • You’ll have 1 minute to complete this step.

2. Swap to Indicator Mount:

   • The heat bed will lower, and the toolhead will move to the offset position, aligning the dial indicator tip directly above the first tramming point.
   • Remove the right nozzle and install the indicator mount with the indicator pre-installed.
   • You’ll have 1 minute to complete this step.

3. Zero the Dial:

   • Once the heat bed raises to the final position, zero the dial.
   • For each tramming point, you’ll have 30 seconds to adjust the screw.

4. Tramming Adjustment:

   • At each tramming point, adjust the screw until the dial reads as close to 0.00mm as possible.

5. Repeat Rounds:

   • The process will repeat for up to 10 rounds.

6. Stopping Criteria:

   • You may stop early if, at the end of any round, all points read 0.00mm and no adjustments were made during that round.
