I updated to the latest firmware (edge) and config file.
With the panel connected (external SD card not configured) the issue persists: occasionally the display crashes (weird symbols), board freezes midway during prints (like: print stops, LED 2 and 3 off for a second, then LED 1 and 3 permanently off)
Without the panel and the respective changes in config it seems to work. But still have to run a long print.
Also new: activating ethernet (with settings which used to work) will cause the board not to boot.
# network settings
network.enable true # enable the ethernet network services
network.webserver.enable true # enable the webserver
network.telnet.enable true # enable the telnet server
#network.ip_address auto # use dhcp to get ip address
# uncomment the 3 below to manually setup ip address
network.ip_address 192.168.178.39 # the IP address
network.ip_mask 255.255.255.0 # the ip mask
network.ip_gateway 192.168.178.1 # the gateway address
#network.mac_override xx.xx.xx.xx.xx.xx # override the mac address, only do this if you have a conflict
smoothie won't boot at all, no green LEDs coming up.
A torture test has been running now for 3 +hrs without issues.
I'd like to avoid starting another project like Octoprint at the moment. There is enough work to do for the coreXY printer and the magnetic tool changer.
Any recommendations how to get the display working reliable?
I'm a bit worried about the ethernet issue as well.
