-
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.
-
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.
-
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.
-
Tramming Adjustment:
- At each tramming point, adjust the screw until the dial reads as close to 0.00mm as possible.
-
Repeat Rounds:
- The process will repeat for up to 10 rounds.
-
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.
