Do the M190 and M109 commands need to go somewhere specific in the start sequence? I still get the same issue with how i tried. Also, considering that it is a dual extruder printer, could that be a part of the problem? As of now it hasn't had the second extruder defined, so i'm wondering if that might cause the printer to not being able to designate which extruder to use? Or does one of them automatically function as the main one?

Hi. I recently bought my first 3D printer, Wanhao Duplicator S4, but haven't gotten it to work yet. Atm i'm stuck at the extruder not heating in any way (currently it's by default set up as a single extruder printer, which is fine in the beginning). This is the default G-Code: Start G-Code 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 G1 Z15.0 F{speed_travel} ;move the platform down 15mm G92 E0 ;zero the extruded length G1 F200 E6 ;extrude 6 mm of feed stock G92 E0 ;zero the extruded length again G1 F{speed_travel} ;Put printing message on LCD screen M117 Printing... End G-Code M104 S0 ;extruder heater off G91 ;relative positioning G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure G1 Z+0.5 E-5 X-20 Y-20 F{speed_travel} ;move Z up a bit and retract filament even more G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way M84 ;steppers off G90 ;absolute positioning As far as I can understand, there's missing a heating command (M104) in the start. I've tried to write it in, but nothing happens. I don't know if I've messed up the sequence when trying so. Also, the bed is heating, but I don't see any commands for the that. Is that a default command by the printer?
