New Ender 3 V3

[Lantecer 0]

Hi all,

 

just found a single post about the new Ender-3 V3`s but that didn't address the problems I face so I`ll try it here.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I`m pretty new to 3D printing and maybe you can help me out a bit if I miss some basics.

 

I have the issue that my printer does things at the beginning that doesn't make 100% sense to me.

 

 

Question 1)

 

When I use the Creality Slicer and look at the start / end g-code it just has the following default text:

 

Start:

M140 S0
M104 S0
START_PRINT EXTRUDER_TEMP=[nozzle_temperature_initial_layer] BED_TEMP=[bed_temperature_initial_layer]

 

End:

END_PRINT

 

What I found so far:

The new Enders have a Klipper-Based Creality OS.

I can't select Klipper as a G-Code Flavor. Does this somehow create an issue?

 

Because I set the printing temperature to 215°C at all points, but shortly before the nozzle purge at the edge of the bed starts, it's rising up to 240°C and stays there.

I have no explenation why. I set the default material print temp to 215°C and also all other temps.

 

 

What am I missing that the extruder temp moves to 240°C all the time?

 

For comparison, the default Ender 3 V3-SE G-Code in Cura looks like that:

 

Start:

M220 S100 ;Reset Feedrate
M221 S100 ;Reset Flowrate
G28 ;Home
M420 S1; Use saved mesh leveling data
G92 E0 ;Reset Extruder
G1 Z2.0 F3000 ;Move Z Axis up
G1 X-3 Y20 Z0.28 F5000.0 ;Move to start position
M190 S{material_bed_temperature_layer_0} ; Set bed temperature and wait
M109 S{material_print_temperature_layer_0} ; Set hotend temperature and wait
G1 X-3 Y100.0 Z0.28 F1500.0 E15 ;Draw the first line
G1 X-2 Y100.0 Z0.28 F5000.0 ;Move to side a little
G1 X-2 Y20 Z0.28 F1500.0 E30 ;Draw the second line
G92 E0 ;Reset Extruder
G1 E-1.0000 F1800 ;Retract a bit
G1 Z2.0 F3000 ;Move Z Axis up
G1 E0.0000 F1800

 

 

End:

G91 ;Relative positioning
G1 E-2 F2700 ;Retract a bit
G1 E-2 Z0.2 F2400 ;Retract and raise Z
G1 X5 Y5 F3000 ;Wipe out
G1 Z10 ;Raise Z more
G90 ;Absolute positioning
G1 X0 Y{machine_depth} ;Present print
M106 S0 ;Turn-off fan
M104 S0 ;Turn-off hotend
M140 S0 ;Turn-off bed
M84 X Y E ;Disable all steppers but Z

 

When using this G-Code I`m running into a coordinate error on every print.

 

For now I put the short version in Klipper-Style into Cura and that starts the print at least.

 

 

 

Question 2)

When starting a print the printer levels the bed every time. Is that normal or somewhere hidden in "START_PRINT"?

 

Question 3)

Between leveling it cleans the nozzle. While doing this it's scratching the bed a little. Is that hard pressure normal?

 

Thanks to every reply!

Creality Slicer is a modified version of UltiMaker Cura.
You can assume your default settings and start/end gcode will be different or act differently.
You will need to contact Creality for explanation about that, this community is for UltiMaker Cura not Creality Slicer.

But I am using Cura?

Right, but as i said anything you pulled from Creality Slicer might not work as expected if at all.

Also since the new Ender-3 V3 (unlike the E3 V3 SE or E3 V3 KE, totally not confusing names there Creality) runs Klipper which Cura does not natively support, that could cause issues. Klipper supports a subset of gcode commands from Marlin (the language all the other Ender-3 printers, as well as many others use) that is enough to run most prints but compatibility can not be guaranteed, especially with Creality who often modify the firmware of their printers so that not all standard gcode is supported.
