What is wrong with my gcode?

Post by Mic_Hazelburn » 17 Dec 2016, 19:25

Hey guys,

I wanted to know, what is wrong with my gcode. The printer is heating up but it won't start at all. First, I must say, that I want to print with the second extruder (hotend 1) because hotend 0 was broken and I bought new euipment for that. So, in the meantime, I want to print and don't want to wait till the hotend 0 is here. ^^

So, here is the gcode from cura 2.3.1:

;Start GCode
;Sliced at: {day} {date} {time}
;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
;Print time: {print_time}
;Filament used: {filament_amount}m {filament_weight}g
;Filament cost: {filament_cost}
;M190 S{print_bed_temperature} ;Uncomment to add your own bed temperature line
;M109 S{print_temperature} ;Uncomment to add your own temperature line
M140 570.000000
M190 S50.000000
M109 T1 S200.000000
G21 ;metric values
G90 ;absolute positioning
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{travel_speed} ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD scree
M117 Printing

;End GCode
M104 T1 S0 ;extruder heater off
M140 S0 ;heated bed heater off (if you have it)
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{travel_speed} ;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

I must say, I'm not very good at the gcode stuff. I took this with some tips of the extruder 1 (T1) that I saw in another thread.
Could someone help me?

BTW. I would like to see some new guide for the actual cura version If this is possible.

Thanks!

Is this the problem?

M140 570.000000 NO S ON THIS VALUE OF 570; should this be S70.00?

Hey Halford,

ah - good eye! Okay, that is done, but now, it starts normal but the steppermotor for extruder 1 is not rotating. What should I change? Hope you can help me.

Good you found the problem; The extruder stepper motor will ONLY rotate when the temp for the nozzle is about 130 degrees.
Set the temp using the controller and wait to be reached. Then move the motor using the move axis function.

Thanks for your help Halford,

it was a little mistake from my side. The cable was not plugged probably, so the contact was not very good!
