Setup automation process (Prusa MINI)

Setup JobOx automation on Prusa MINI

There are few different ways how to setup and run an automation process on a JobOx system. Some of them are entirely software based, other requires additional hardware.

The simplest way starting with automation process is by using our browser based application jobox.app which works online and offline. This method is entirely software based and no additional hardware is needed.

All other methods requires third party hardware or software. Each of them has it strength and weaknesses compared to jobox.app and the choice of a best suitable solution should be met individually based on a certain use case. We are introducing these methods as possible options, however we are not affiliated with any of these service providers or product retailers.

Jobox.app (software based / open source)

Jobox.app is a browser based application which takes multiple GCODE files and merge them together into one single file. The operation is very simple.

  1. Navigate to jobox.app
  2. Click on “Choose File” and select one of your GCODE files
  3. You can increase the “Repeats” number to print one GCODE multiple times
  4. If you need some more files, you can add more lines to the list by clicking on “+ Add file”
  5. Lines can be sorted by drag-n-drop…
  6. and removed using the button on the right.
  7. You will notice that each line indicates the size of the loaded file …
  8. There is a scale underneath the list, showing the estimated size of the combined file. It needs to be kept in mind, because the total file size should not exceed 450 MB. Bigger files cannot be loaded by Prusa MK3s.
  9. Enter a name for your compilation file (if empty an automatic name will be generated).
  10. Clicking on “Merge files” will combine the files into a one single output file and start the download. The output file can be found in the download directory of your browser.


Data security and privacy

We care about your data security and privacy and that’s why the jobox.app is designed in a way, that your files never leave your computer and are processed locally (on your computer by a technique called JavaScript), even if the user interface runs in a browser.

By the way, you don’t even need internet connection for using jobox.app. You can save it locally and use offline.

Learn how ...
  1. Navigate to jobox.app
  2. Right click somewhere on the white space to open a website menu
  3. Click on “Save as” or “Save page as”
  4. Select the place where the page should be saved,
  5. Make sure to select “HTML only” as a “File type” option and click “Save”.
  6. Now instead navigating to www.jobox.app you can just double-click on this file and using the full functionality offline.

 

Repetier (hardware based / proprietary)

Repetier server is a print management software which can be installed on your own hardware. There are versions for Raspberry Pi, Windows, Linux and Mac. Repetier server can be used for two printers for free. To operate with more printers a "light" or "pro" version is needed (one time payment without subscription).  Read more here: www.repetier-server.com

Please note: the method provided below is not tested yet! We prepared this rough guidance based on information provided by Repetier in their support forums and user manual (se sources below).

According to Repetier, the only step which is need to be done is sending a corresponding command to the server (perhaps using _console):

@autostartNextJob (if you are using Repetier version 1.2.0 or newer)

@autostart_next_job (if your Repetier version is older than 1.2.0)

Since the loading and ejecting routine for JobOx is already included in your GCODE file (JobOx slice profile is mandatory!) no additional code is needed (neither before nor after a print). After the printing job is finished and the building plate is ejecting the next print job in the queue will be started automatically.
