HI, I'm new here !

I recently converted a delta printer with a Ethernet duet3d+tft , 1.03 version. I've just installed 2,02 firmware. After the 3.3volts convertion of the bl-touch averything started working flawlessy. I just have one trouble at the moment, when I restart the printer the Bl-touch starts flashing, to let it stop I home all axes and unplug the communication wires (not the black/white) and plug it again. Then the needle pulls in and out and then the red light stays on and I can launch the auto calibration.

Another question, here is a way to let the printer make a noise at a certain point of the print? I need to insert another printed part inside the one it's printing

Thanks in advance
Luca
