3D Printing stuff is easy

I want to have something more stable and useful for everybody in the lab about how to setup and use 3Dprinters.
I first used printers with a direct USB connection. I like that specifically for the direct manual control of the machine.
But it’s not very ergonomic for the noob, who want to plug and play on everything.

In the past, I used :

  • replicatorG (thing-O-matic)
  • Slic3r (thing-O-matic)
  • Repetier host (3Drag/K8200) with Slic3r and curaEngine.

then a couple years ago, I switch to mattercontrol who use a fork of curaEngine, curaEngine original and Slic3r for the slicing part.
This one offer a lot of manual control and a software auto-leveling, very handy when you don’t have hardware auto-leveling.

Of course,
I tried several time the Cura software but the main disadvantage is the lack of …. manual control.
Yeah, I really don't trust these automatic stuff because when you build your own printers, you like to have access to these last minute settings to adapt, correct, learn what do what.

But these days, the new version of Cura is packed with new and advanced functions which is quite cool to work with. And it easily overcome the missing manual control.

Basic Setup

  • Install Cura, actual version is 3.4.0
  • Create a new profile for the printer, could be based on prusaI3.

Here for Anet E10, it’s basically the default settings but with

  • the X,Y,Z size adjusted,
  • heated bed checked and
  • material diameter manually measured with the caliper.

Be sure everything is set and calibrate physically on the machine and test your settings.

How to save/import your settings

First way

It’s possible to save settings in Cura as a “project”. This will save everything, printer settings, materials and model.

>save Project...

Then to import settings after a fresh install or when using a new printer, you can just go on Openfab’s github,
Download and open as project the AE10_Calibration - Box.curaproject.3mf

In this file, you’ll have 3Dprinter settings for AnetE10, one PLA normal setting (or more if set) and a big flat box just to help a first calibration. (> to document later)

You should be good to go from there. YEAH :)
Next: you can follow this step by step for your first printing

Second way

Everything is save localy here (on windows): ..\Users\AppData\Local\cura\3.4\...
note: these are “hidden folder”

This could be simple as a copypasta, OR set as a repo through github to keep it update with new materials settings and new printers…

work in progress... Help is welcome

Next step?

Here in the lab, Openfab, we still have several machines to upgrade, levelup and optimise.
I don’t have time to take care of these.
If you want, you’re welcome to help and it’s a great way to earn some 3Dprint technical badges and more XP.
Then you could even access to maintenance jobs that we receive times to times.

How to contribute?

  • Setup github to log and pull new settings/presets from advanced skilled members.
  • Create setups for each of the printers. Anet A6, E10 and Fabrikators v2.
  • Setup Octoprint for a better managment?
  • I have a geeetech to upgrade, bad Z axis.
  • I have a tevo tarantula dual extruder to rebuild and upgrade.
  • I have 2 leveling sensors to install.
  • I have a M3D micro printer to levelup also, it’s working but… mheeee. I don’t like their BS software.
