Acquisition Details	I have pre-donated my v400 to the space. This machine is not yet the spaces property, but is fulfilling a need for a working printer. I am waiting on a replacement, bigger personal printer to arrive for my own use in my own home, at which point I would be donating the v400 anyway as it will become surplus to requirements, instead of selling it on, because I feel the space would benefit from access to it more than selling it to someone. When the time comes, this machine will be freely given to the space at no cost. I want to run some educational training on how to tend to the machine before handing it over completely. In the mean time, the space can borrow it. When my new FLSUN S1 printer turns up, I will hand over ownership, hopefully to a maintainer team that I intend to foster. I also intend to remove the tablet that controls it and replace it with a managed print controller running on a space ewaste computer.

FLSUN V400 Printer

Using the printer:

The v400 is a delta printer, its kinda fun to use. Its pretty hardy and fairly durable compared to an average 3d printer, and also fairly fast. Baring this in mind, if we stick to a known recipe of plastic and printer settings, it should Just Work:tm: most of the time.

It likes to run ESUN brand PLA+ (PLA-ST which is PLA with added herbs and spices that make it stronger) which is often < €15/kg. I've had great success with ESUN PLA+ and never had a clog with it.

Orca

Orca is nicer than Cura, so this one is recommended.

Import v400 print settings:

Then click Import and import the v400 profile: https://wiki.techinc.nl/images/8/8d/V400.curaprofile.gz (you will need to un-gzip it, mediawiki wont let me upload the .curaprofile file alone even though its technically already a zip)

Finally, connect to the printer:

On the "Connection" tab, set the connection address: (at http://10.209.10.174 at time of writing)

And on the "Upload" tab, set the Following settings:

• UFP with Thumbnail enables the printer to show a thumbnail of the print its going to run
• Fire & Forget means you wont be sat there wondering why your print isn't running after pressing upload
• Automatic job start for the above reason too.

Optional: Configure Timelapse

You need to inject some gcode to your process in between each layer:

Find the Modify G-code button under Extensions => Post Processing => Modify G-code:

Then insert a new Post Processing Script as "Insert at layer change" set to Before / TIMELAPSE_TAKE_FRAME:

All done!

Happy printing!
