I just did a conversion of an ender 5 plus to a mini 5+. My Y axis quits on most prints after about 2 hours and I get phase not detected errors on both phases. The first time I had the current set to 800. I bumped to 1200. Same. 950 same failure. (1200 made the motor pretty warm and I subsequently found a thread suggesting that Creality sets Y axis on that model to 900-950. ) As you might imagine it makes a mess. I've played around with cabling. Is there a log or other diagnostics that can help me get to the bottom of it? Thanks

@phaedrux I'm pretty sure I'm a victim of the macro mentioned in this thread. The first line deletes the config.g file followed by 4 or 5 other deleting and copying type operations. I'm calling it a smoking gun. That evening it was a [insert explicative here] smoking gun. I recreated the file and put a new copy of firmware on the SD card and got going again.

I'm suffering same thing. I'm just getting to the end of commissioning. I sent a G0E1 to move the extruder. I got a warning that no tool selected. Then lost web connection and now cannot connect with serial either. Config.g and anything that looks like a backup is missing except the config.json. Firmware was updated earlier today. After placing a new config.g file on the SD card, still cannot connect. I'm assuming next step is try to reinstall the firmware to the SD?
