- Here are the profiles I use with Cura. I'm sharing with my YouTube audience. Use at your own risk. They are not perfect but gives you a great starting point for using Cura with a Creality Ender 3, Ender 5, CR-10 and CR-10 Mini 3D Printers.
- To find the best support settings I am using Cura 2.I have tried Cura 15 (which is actually the former version of Cura 2) but it has way less settings. I have also tried Meshmixer and its 'tree supports': the branches are interesting but I got some problems because the supports were not placed where they were supposed to.
- Cura 4.2 is available. But if you go to the Marketplace on Cura and install the printer settings add-on you can go in and adjust the max Z speed to 10 or more.
UPDATE: This method is a bit hacky, and breaks with updates – best to check on my newer method here
Wow this was harder than it should have been, so I'll post what I can here to help you also.

We have 3 x Makerbot Replicator 2 3D printers, and for years used Makerware until it was discontinued for our printers and for Ubuntu it seems. So we've made the switch to Cura where all the cool kids hang out.
Of course Cura is primarily made for Ultimaker printers, but it can be configured for many others.
First up, I'm using it in Ubuntu Linux (18.04) so locations of files might need to be changed for your config files as needed.
Step 1: Set up your printer
I chose Makerbot Replicator from the printers page, and made a couple of changes as shown here:
I also renamed the machine name to 'Replicator 2' just so I would remember.
Step 2: Start and end GCode
You'll need some custom Gcode so here it is (picked from various places and organised after some testing).
Start Gcode:
; — start of START GCODE –
M73 P0 (enable build progress)
;this next line won't work, but has the steps command
M92 X88.8 Y88.8 Z400 E101 ; sets steps per mm for Rep2
G90 (set positioning to absolute)
(**** begin homing ****)
G162 X Y F4000 (home XY axes maximum)
G161 Z F3500 (home Z axis minimum)
G92 Z-5 (set Z to -5)
G1 Z0.0 (move Z to '0')
G161 Z F100 (home Z axis minimum)
M132 X Y Z A B (Recall stored home offsets for XYZAB axis)
(**** end homing ****)
G92 X147 Y66 Z5
G1 X105 Y-60 Z10 F4000.0 (move to waiting position)
G130 X0 Y0 A0 B0 (Set Stepper motor Vref to lower value while heating)
G130 X127 Y127 A127 B127 (Set Stepper motor Vref to defaults)
G0 X105 Y-60 (Position Nozzle)
G0 Z0.6 (Position Height)
; — end of START GCODE –
End GCode:
; — start of END GCODE –
G92 Z0
G1 Z10 F400
M18
M104 S0 T0
M73 P100 (end build progress)
G162 X Y F3000
M18
; — end of END GCODE –
This of course all assumes you don't have a heated bed (also makes sure it doesn't send heated bed commands which make the machine complain).
Step 3: Install X3G file converter Animal crossing nitendo ds.
Go to the 'Marketplace' button at the top right of your Cura window and in the marketplace search for 'X3GWriter' and install it. Restart Cura so that it comes live.
Step 4: Modify X3GWriter so that it always detects 'Replicator 2'
There seems to be a problem with X3GWriter in that with the above setup it always detects the machine to be a replicator 1, which is a problem as they have different amounts of steps per mm. You'll know this because if you have a Replicator 2 and you try to print an object, it'll keep printing larger than it should be. I'm sure there's another way to make it detect 'Replicator 2' but in the mean time I just changed it to always be Replicator 2 as that is all I have.
Locate your plugins folder – for me it's in /home/username/.local/share/cura/4.3/plugins (where username is your username).
Cura 4 2 Settings Windows 10
Go into the X3GWriter folder (and again into it, it's nested twice – the path for me is: /home/username/.local/share/cura/4.3/plugins/X3GWriter/X3GWriter/)
Open 'X3GWriter.py' with your favourite text editor. Be careful in here, it's a python script so you want to use spaces, not tabs to indent, and indents matter. If you destroy it you may have to just remove the plugin and install it again.
We're looking for the line like this:
return machine if machine in X3GWriter.known_machines else None

We're looking for the line like this:
return machine if machine in X3GWriter.known_machines else None
Cura 4 2 Settings Xbox One
Note again that it's indented with spaces in front. Put a # in front of this line to comment it out so it doesn't get read like this:
#return machine if machine in X3GWriter.known_machines else None
Now go to the next line, press space until you're lined up with the line above and put in:
return 'r2'
Cura 4 2 Settings Free
Save the file and close Cura, then restart it. If all is well, you'll find you can now export files that will print properly and be read by your Replicator 2.
If you find the X3G file option has disappeared from your list, then the plugin is broken. Check your syntax in the plugin file and try again.
Finally I can use a nice slicer on Linux and hang out with the cool 3D printer kids!
