      Thank you in advanced for any help!

      I setup my DBOT and it all ready to test print.

      Im using simplfied 3d, I used the settings based on the build guide. When I go to upload and print the printer start the heating process. About 1min into the process the print shows 100% complete, the heaters get up to temp , the system homes and then nothing.,

      Any Ideas?

          How odd. Have a look at the gcode file to see what is in the start gcode (the code put in by s3d/slic3r at the beginning before the print starts) to see if any of that is weird. The wiki has a list of all the gcodes and their usage which can be a handle reference.

            If I understand correctly, the problem occurs after the printer has homed? In which case, it could be something screwy with your homing files. Can you post them. Ian

              @deckingman yeah seems to happen right after it homes. Im using a config generated by the configuration tool

                Here is also part of the GCODE from one of the test cubes

                M104 S215 ; set temperature

                M109 S215 ; wait for temperature to be reached

                  Well did more testing seems its not based on the homing it based on the heated bed coming to temp or right when it switchs from telling it to finish heating the bead and start heating the nozzle

                  The process is upload, heated bed get to 65C , it homes and then says its finished

                    Your cube gcode waits for bed temperature to be reached, but it doesn't wait for hot end temperature to be reached. It's probably a setting in your slicer. Or you can add M116 to your slicer start gcode to force it to wait. Scratch that, somehow I overlooked the M109.

                      I finally figure it out, after it homed twice for some reason it killed the job.

                      I changed the config provided below for homeall and now its printing.

                      Now just have to tune the extrusion

                      G91 ; relative mode
                      G1 S1 X-240 Y260 F3000 ; course home X or Y

                      G1 S1 Y260 ; course home Y
                      G1 X4 Y-4 F600 ; move away from the endstops
                      G1 S1 X-10 ; fine home X

                          It's what M109 does - somehow I overlooked that command.
