The auto-calibration procedure ensures your Vision Miner 22 IDEX achieves high accuracy and sensitivity by precisely calibrating the nozzles and other parameters. It is crucial for optimal printing performance.
Auto-calibration allows the printer to sense when both nozzles are touching the aluminum build plate with high accuracy. For this to work, the nozzles must be perfectly clean. The calibration process includes:
- Z Offset Calibration: The Z offset is calibrated.
- Tool Height Calibration: Both nozzles are calibrated to the same height within a tolerance of 50 microns.
- XY Plane Calibration: The printer ensures both nozzles align in the XY plane by touching a square hole with each nozzle and matching their offsets.
During nozzle probing machine will show Red Error box saying: Error: Probe was not triggered
This is Expected and Normal behavior.
- Go to the Dashboard.
- Find
Macros and select Auto Calibration
- Enter temperatures for both nozzles separately.
- Use the temperature of the filament loaded before, or 250°C if the machine is brand new.
- Ensure no build plate is installed as the nozzles need to sense contact with the raw aluminum build plate.
- Removing the build plate is crucial to avoid damage to the machine.
¶ 4. Automatic Homing and Cleaning:
- The machine will home automatically and clean both nozzles.
- Clean both nozzles manually, ensuring they are perfectly clean.
- Click
OK once nozzles are clean to proceed.
Verify that the heat breaks are not sticking out more than 1-2 mm from the heat sink.
If they are, cancel the calibration using the Power button and adjust them by loosening the set screws and moving them up all the way.
- The machine will home again and start calibrating the tool height.
- If machine measures deviation above 50 microns, calibration will be recommended.
- Loosen the screw holding the heatbreak screw using a 2mm hex screwdriver or Allen key. 🔥 (Caution HOT!) 🔥
- Move the heatbreak and hotend down slightly (2-5mm) using the same tool. 🔥 (Caution HOT!) 🔥
- Retighten the screw slightly to prevent wobbling and inaccuracy. (Heatbreak should still be able to move up and down)
- Click
OK to start the calibration.
- The machine will move the build plate to align the nozzles.
- Tighten the heatbreak screw permanently.
- The machine will recheck the alignment and confirm calibration success.
- If successful, the machine will proceed to Z-offset calibration and XY-tool alignment.
- If deviation is still too high machine will suggest to repeat the procedure.
- The machine will move to its home position and signal the completion of the calibration.
Congratulations! Your 22 IDEX is now calibrated and ready to print. The hardest steps are behind you, and your machine is set to produce high-quality parts.
