Describe your issue:
…Trying to use a zero w as replacement for a pi 3B+. Used kiauh to install klipper, moonraker and mainsail. Everything seems to work with old klipper.bin and printer.cfg until time to connect. Kiauh indicates mcu is on /dev/ttyAMA0. Putting that into printer.cfg causes klipper to simply spin. klippy.log last few lines indicate it is waiting for a connection
"mcu ‘mcu’: Starting serial connect
webhooks client 3038670272: New connection
webhooks client 3038670272: Client info {‘program’: ‘Moonraker’, ‘version’: ‘v0.8.0-318-g9813011’}
“jroe@picam:~ $ ls -l /dev/serial*
lrwxrwxrwx 1 root root 7 Mar 1 10:17 /dev/serial1 → ttyAMA0”
It appears zero w doesn’t implement usb hotplug the same as 3 B+. Does anyone have a fix, maybe in the zero w?
