Hello all,

I have a Ender 3 pro with a BLtouch installed. The printer has been working fine until a couple of days ago. z-axis will not go down for auto home and BLTouch just flashes. I don’t think it’s an issue with installation because I’ve printed several items since installing. Actually I completed a part this morning and when I went to print another item – I started having this issue.

Note: The only change that happen. I moved the printer from my kitchen table to it’s own cabinet in the garage.

Any thought on what I’m missing?

Not a critical problem but happens sometimes.

The reason is the weak cable connection. You need to reconnect the BL touch cable and restart the printer.

Funny thing is, my BL touch was flashing and after I moved the printer to a new table, the BL touch works again.

@eli-liu I have the same problem, and have checked the connection with a multimeter, all of the wires seem to have a good connection
