**Really getting started**

Workflow options

    - Upload a file to the web interface
    - Put a file on a USB stick, insert it into the printer and select it with the hand held controller
    - Probably some other thing


There is a web interface at [[http://192.168.1.61/#/|192.168.1.61]].

It looks like this:

There is a little draw in the front left for tools.

For slicing software, Cura from https://github.com/Ultimaker/Cura seems to be best.
Recent cura has built in profile for this printer. 
Cura AppImage has a missing lib for running on recent debian: [[https://theitgarage.wordpress.com/2024/12/22/running-cura-5-9-on-debian-unstable-sid-and-debian-13-trixie/]]


** Benchy **

Gcode for a benchy that should print in about 30mins: [[https://user.fm/files/v2-fdad9e17f841f25407e44c9d3979fdc9/EN4MAX_3DBenchy.gcode]]

This was sliced with "Extra Fast - Draft" to optimise for print time so quality isn't going to be great.  

This should come out something like this: [[https://photos.app.goo.gl/EDvE2rFbJYfZoEMo7]]

Things that benchy tests (beyond just if you can print anything): [[https://www.3dbenchy.com/features/]]

Pros
  * Some members ones from this range already, so in-house knowledge
  * Big print size, so useful for people who have a smaller one at home
  * [[https://github.com/OpenNeptune3D/OpenNept4une|Open source software]] for the printer

Cons
  * My (Alex) experience of Neptune Pro 3 - making sure the bed is evenly heated before calibration else it doesn't work. So a bigger bed on NP4 might make this more of a hassle?  Looking into this, it seems like care with bed heating and calibration is needed.
