Printer suddenly stops mid print
Hi, I'm trying to print to a Tronxy X3A (Marlin v. 1.0) with Repetier-Host 2.1.3 and the print starts of ok, but then suddenly stops with an error message about communications. I've gone into the windows settings and changed the buffer to the lowest settings, but it doesn't help. I'm using the slic3r software. It's pretty random where it will stop. Anyone have any ideas about why it suddenly stops? It prints fine off a microsd card. It's very infuriating.
So also serial connection is still open the firmware either crashed or the communication stack has a problem preventing communication to further work. This happens if power is not stable enough or if there is somehow cross talk to communication cables. Disconnect usb unpower printer and restart it and communication will work again. To prevent it form happening again you need to find the source. Use other usb cable, other usb port, check if cables come close to high power cables like heaters or motors. If it happens frequently you can also try to print in dry run mode if firmware supports it. That disables heaters and the most frequent source of such problems. If the problem then disappears you know where to look for.
