Cura settings for the Original Prusa i3 printers  

Re: Cura settings for the Original Prusa i3 printers

Works fine, I have altered the Start and end code to my settings based on excellent work by other forum members, but with a few tweaks of my own.

Start G-Code:
G21 ; Set units to millimeters
G90 ; Use absolute positioning
M82 ; Absolute extrusion mode
G28 W ; MUST FIRST home all without mesh bed level or else risk nozzle crash!
G1 X10 Y200 Z110 F1000 ; Lift nozzle to allow cleaning of any filament danglers
M1 S10 ; Wait approx 10s to allow time to clean nozzle ooze then continue without user intervention or press knob to continue
G0 X70 Y70 Z0.5 F1000; PINDA warms faster near bed
M104 S150 ; Preheat extruder to no ooze temp to help warm PINDA
M140 S{material_bed_temperature_layer_0} ; Set bed temp
M109 S150 ; Wait for extruder temp
M190 S{material_bed_temperature_layer_0} ; Wait for bed temp
M860 S35 ; Wait for PINDA temp to get to 35 Deg C
M104 S100 ; Drop extruder to lower temp to minimize PINDA temp rise during mesh
G80 ; Mesh bed leveling, this will be 3 x 3 or 7 x 7 based on your settings in the LCD menu
G92 E0.0 ; Reset extruder distance position
G1 Y-3.0 F1000.0 ; Go outside print area
G1 Z3.0 ; Lift head slightly during heating of nozzle
M104 S{material_print_temperature_layer_0} ; Set extruder temp
M109 S{material_print_temperature_layer_0} ; Wait for extruder temp
G1 Z0.6 ; Move slightly above bed for easy clean intro line
G1 X60.0 E9.0 F1000.0 ; Intro line for 0.4mm nozzle use E5.0 for 0.25 nozzle
G1 X100.0 E21.5 F1000.0 ; Intro line for 0.4mm nozzle use E13.0 for 0.25 nozzle
G1 X95.0 E21.5 F1000.0 ; -5mm intro line @ E=0 to move left into the extruded filament to wipe other side of nozzle into intro line
G1 X100.0 E21.5 F1000.0 ; +5mm intro line @ E=0 to move back to the right leaving buildup from left of nozzle stuck to intro line
G1 Z0 ;Lower head back to normal Z after intro line
G92 E0.0 ; Reset extruder distance position.

End G-Code:
G92 E0.0 ; Reset extruder distance position
G1 E-1.0 F2100;Anti stringing retract at end of print
M104 S0 ; Turn off extruder
M140 S0 ; Turn off heatbed
M107 ; Turn off fan
G1 X0 Y210; Home X axis and push Y forward
M84 ; Disable motors

Hi Chocki,
thanks for sharing these, I forwarded them to our "settings guru" 😎

Re: Cura settings for the Original Prusa i3 printers

What should I select if I would like to print TPU/Flexfill materials? Thanks!

RE: Cura settings for the Original Prusa i3 printers

NOTE:

CURA has released version 4.1 of their slicer software, it looks like the existing PRUSA profiles may no longer work.

They certainly do not work if you update CURA from 4.0 to 4.1 and keep existing profiles.

RE: Cura settings for the Original Prusa i3 printers

I ended up uninstalling CURA 4.1 and all settings profiles (But it looks like it does not uninstall everything which in this case turned out to be a good thing).

Installed Cura 4.1 but did not start it!.

Copy the three files over as per instructions here:

https://manual.prusa3d.com/Guide/How+to+import+profiles+to+Cura+3.4+(Windows+&+macOS)/1033?lang=en

Just select Ultimaker Cura 4.1 as the directory instead of Ultimaker Cura 3.3 as in the instructions above.

Now start Cura and hey presto, everything already set for PRUSA I3, just like it was with Cura 4.0

RE: Cura settings for the Original Prusa i3 printers

If anybody else is using Cura on Linux, you might be interested to know that the files go into the folder ~/.config/cura/4.0/resources/

I had also just finished building a machine profile for Cura, and got it to work well. With the amount of effort I put into building that, I'm hesitant to switch. Anyone had time to use these new settings?

You want to chuck your settings up here as well? I'm doing some overall tuning with my machine be interested in at least comparing settings in-game and in with some basic test prints.

Edit: Also I want to thank you for providing cura settings and a really nice manual on how to do it!

RE: Cura settings for the Original Prusa i3 printers

He everybody,

I found that CURA 4.3 works perfectly if I do not import the Prusa official profiles. it appears that this import generates disruption in the program that significantly reduces the print quality.

RE: Cura settings for the Original Prusa i3 printers

Nice, thanks but ... I'm installing in on Cura 4.3 under Ubuntu Linux and there is no 'meshes' subfolder in the configuration folder

$USER/.local/share/cura/4.3

Should I create id manually?

Regards,

P.

P.S. Would be nice to provide Linux installation manual as well... There is one of Win and Mac only 🙁

Hello all,

Cura version 4.5 released yesterday.

RE: Cura settings for the Original Prusa i3 printers

Can we get updated profiles for Cura 4.6 for latest MK3S firmware with Linear Advance enabled?

RE:

Have the Cura profiles stopped being updated and abandoned?

Have the Cura profiles stopped being updated and abandoned?

I've also been wondering if these profiles have been validated in any of the newer cura versions and if they're still valid, and if any updates are necessary or will ever even happen

RE: Cura settings for the Original Prusa i3 printers

I have no clue where the profiles for the I3 series in my Cura (originally ca. 2018, upgraded many times) came from, but they were in there long before I got my Prusa printer.

The speed they had was MUCH too fast on the first layer, but some simple tweaks tamed it and I consider it now to be in the 'aint broke, don't fix it' category.

If there are some updated profiles which have been shown to be stable, I might be interested in updating them.

RE: Cura settings for the Original Prusa i3 printers

Same I had issues with these prusa profiles for cura. And the new ones that come with Cura also have issues. I thought they were thoroughly tested, but I guess not.
