I’ve been using this setup for over a year without problems. Reinstalled “2020-05-27-v1pi-no-hotspot”. Connects fine. The X Y Z control buttons in CNC.js are active, but they do not move the steppers.
I can manually move the steppers with my smart controller. The problem is when I do, I get the message “Server has stopped working”. I must reboot my RasPi to connect again.
Fortunately, I can print using a compact flash card in the smart controller, but it is not convenient.
