My printer has two nozzles. On first layer (M104 s240) this command shut the hot end off causing a thermal error. Not sure why but it might have something to do with repeating the same temp setting. At start of the first layer I manually tuned temp changing it to 241 and the hot end turned back on and the print continued normally. Just to see I tuned temp back to 240 and the print continued normally. Next in cura I will change the temp of the initial layer so that it is at least 1 degree off from the print temp.

I have the same issue with my printer. It seems to be a cura slicing error that causes the hot end to turn off causing thermal error. Then when it moves to standby position the hot end turns back on and heats to set temp and ejects the filament. This repeats over and over.

I have the same problem. I start print then after bed leveling and head heating the filament is ejected. The printer is pause awaiting filament change. I prefer to install filament before print start. I do not have any plugins Machine settings: G21 ;metric values G90 ;absolute positioning M82 ;set extruder to absolute mode M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G28 ;Home X/Y/Z G29 ; AUTO BED LEVELING M104 S{material_print_temperature} T0 ; Preheat Left Extruder M104 S{material_print_temperature} T1 ; Preheat Right Extruder M109 S{material_print_temperature} T0 ; Preheat Left Extruder M109 S{material_print_temperature} T1 ; Preheat Right Extruder G91 ;relative positioning G90 ;absolute positioning M218 T1 X34.3 Y0; Set 2nd extruder offset.
