Some of my printing always stay in last step,the hotend do not homing.But some printing hot end will go home when finish printing.I am using 0.8.4 version,last gcode is
M104 S200 ; turn off temperature
M190 S75 ; set bed temperature
G28 X0 ; home X axis
G28 Y0 ; home Y axis
M84 ; disable motors
but some are do not executing these g-code,especially that I draw it with Ironcad then output stl files.
