How do I configure my BLTouch?
How to install BL-Touch on the Ender 3 V2 3D Printer (No Adapter Board Version)
- Step 1: Access your printer’s motherboard.
- Step 2: Remove z-axis limit switch.
- Step 3: Connect and thread BL-Touch cable.
- Step 4: Mount the BL-Touch on the Nozzle Assembly.
- Step 5: Update Motherboard Firmware.
- Step 6: Determine and Set Z-offset.
How accurate is BLTouch?
As for it’s accuracy, the BLTouch claims an accuracy of 0.01mm with a repeatability of 1%.
How do you test if BLTouch is working?
How can I tell if BLTouch is triggering?
- During startup: BLTouch extends and retracts several times.
- In the LCD menu for BLTouch; select CMD:Self Test : BLTouch turns red, extends and retracts several times.
- In the LCD menu for BLTouch; select CMD:Extend : BLTouch extends.
How do you troubleshoot a BLTouch?
BLTouch Troubleshooting
- Avoid Clones. This guide assumes you are using a genuine BLTouch from Antclabs.
- Double Check Your Wiring.
- * Cut the Trace.
- Note that BLTouch V3+ no longer has a trace and is not needed to work with the Duet.
- Use the Resistor.
- Test the Probe First.
- Upgrade the Firmware.
- Use Probe Type 9.
How do you test a BLTouch?
When the BLTouch is first powered up it does a self test – Starting with the pin up it them goes down/up 3 times and ends up the the LED on solid. Continuous flashing means that there is an obstruction or fault.
How does the BLTouch Level the bed?
The key difference between an inductive probe and the BLTouch is that the BLTouch sensor physically touches the bed in the leveling process. The inductive probe uses currents induced by magnetic fields to detect metal objects nearby, eliminating the need to physically touch the bed in order to sense it.
What does Auto bed leveling do?
If your printer supports automatic bed leveling, this usually means that it includes some type or proximity sensor or switch near the tip of the extruder. While printing, the printer’s firmware will actively use this information to adjust the nozzle position as it moves across the bed.
Why is BLTouch always red?
It’s a message to check Wiring because your 3D printer board is already sending a control signal to BLTouch before BLTouch power is turned on. Don’t worry, your 3D printer and BLTouch work perfectly even if the Red LED flashes at 80% duty.
Do you need auto bed leveling?
Bed leveling is meant to compensate for any anomaly on the bed, and it is usually done with respect to the printer’s axis; not the laws of gravity. Fortunately, there are 3D printers that come with an automatic bed leveling feature, used to confirm that the printing platform is level whenever you’re preparing to print.
