hallo there when i use the pc to print a file every thing is all-right . the printer has terminated the job without problems ...when i try to reprint the same file(job) using the direct print with the SD card the printer stopped a 88% when i try to do some think to keep printing and not loose my job...

halo friends
i bought also the auto leveling sensor but i think i can not be in a condition to change the firmware
so my question is .....can you find for me a "sensor ready " firmware to upload and do my job ?
thank you very much
