Hey everyone,
I’m having some problems with the BLTouch on my Ender 3 Pro (v4.2.2 motherboard). Recently, it started probing the air instead of the bed surface. It had been functioning perfectly fine until one day when it suddenly stopped working. Just to provide some context, I have a dual Z-axis setup installed, and the BLTouch stopped functioning shortly after the installation. However, I did test the actual BLTouch itself, and it seems to be working fine when I used the test feature in the printer’s menu.
I would greatly appreciate any help or advice you can offer to resolve this issue. Thank you in advance!
“Hey there! I’m sorry to hear that you’re facing issues with your BLTouch on the Ender 3 Pro after installing the dual Z-axis. I had a similar problem before, and here are some steps that might help you troubleshoot the issue.
Firstly, double-check the wiring connections for the BLTouch and ensure they are correctly connected to the motherboard. Make sure the wires are securely seated in their respective connectors and that there are no loose or damaged connections.
Secondly, verify if your printer’s power supply can handle the additional load from the BLTouch and dual Z-axis. Sometimes, insufficient power can cause the BLTouch to malfunction. Consider upgrading your power supply if necessary.
Next, review the firmware configuration for the Z-axis. When you installed the dual Z-axis, you might need to adjust the firmware settings to accommodate the new setup. Make sure you have the latest firmware installed and properly configured for your setup.
It’s also important to ensure that the BLTouch is correctly mounted and aligned with the printer’s nozzle. Improper alignment can lead to inaccurate probing. Perform a thorough calibration of the BLTouch using the printer’s menu options to ensure it is properly calibrated for your bed.
Lastly, confirm the compatibility of the BLTouch and dual Z-axis with your Ender 3 Pro’s v4.2.2 motherboard. Check if there are any known compatibility issues or specific firmware configurations required for the dual Z-axis and BLTouch combination.
If you’ve already tested the BLTouch under the test section of the menu and it works fine, the problem might lie with the configuration or wiring. I suggest revisiting the installation steps for the dual Z-axis and BLTouch to ensure everything was done correctly. If you’re unsure about any specific steps, consult the installation instructions or reach out to the manufacturer or the Ender 3 Pro community for further assistance.
I hope these suggestions help you resolve the issue with your BLTouch. Good luck, and let us know if you have any further questions!”
