Gcode 3.4.1

Recommended Posts

The gcode does not work as expected in Cura 3.4.1

 

 

It's like this in the Start code

;Sliced at: {day} {date} {time}

;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}

;Print time: {print_time}

Because you use old, deprecated replacement patterns. Use “material_bed_temperature” instead of “print_bed_temperature”, and “material_print_temperature” instead of “print_temperature”.

Could you tell me if you can remove these lines?

Hello

 

I also have a problem with the code ahead of the 'start code'

My machine is a UMO with heated bed and dual extruder. I use the nozzles to keep different materials loaded, rather than as dual extrusion. I also need to keep the working area at maximum, so have created a single extruder machine that uses the second nozzle. However, the code at the top (shown in bold):

;FLAVOR:Marlin
;TIME:18013
;Filament used: 7.09843m
;Layer height: 0.15
;Generated with Cura_SteamEngine 3.4.1
M190 S60
M104 S210
M109 S210

M82 ;absolute extrusion mode
G21 ;metric values
G90 ;absolute positioning

 

...seems to get both nozzles to heat up.

How can I stop this code being written?

 

Thanks, Colin

Make sure your startgcode contains the literal strings “{material_print_temperature}” and “{material_bed_temperature}”, even if it is in a comment. Cura will see this as a preheating sequence, and won’t add one of its own.

Thanks, that works perfectly.

 

Here is my start code for reference:

 

T0 ;Switch to the 1st extruder

M104 S0 ;switch off nozzle 0

T1 ;Switch to the 2nd extruder

M190 S{material_bed_temperature} ;Set bed temp and wait to reach temp

M109 S{material_print_temperature} ; Set extruder temp and wait to reach temp

G4 S20 ;Wait for extruder temp to stabilise

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 F9000 ;move the platform down 15mm

G92 E0 ;zero the extruded length

G1 F200 E15 ;extrude 15 mm of feed stock

G92 E0 ;zero the extruded length again

G1 F9000

;Put printing message on LCD screen

M117 Printing...

 

I have also used this code when using the first extruder, but with the nozzle numbers reversed in the first 3 lines.

Note that I have added a pause (G4 in line 6) to allow the extruder temperature to stabilise, and increased the length of the priming extrusion.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
