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.

OctoPrint is an open source 3D printer controller application, which provides a web interface for the connected printers. It displays printers' status and key parameters and allows user to schedule prints and remotely control the printer. The main advantage of OctoPrint is its ability to operate remotely and there is a huge amount of different plugins like "Continuous Print" introduced in this section. However to run OctoPrint additional hardware is required. In most cases a Raspberry Pi is used but there are also few alternatives. This guidance will only explain how to use JobOx with an existing OctoPrint setup and is aimed at users who already familiar with this system. If you are interested in learn more about OctoPrint in general, please visit octoprint.org.

Karmen enables you to queue and run G-codes in a print queue. If you have a JobOx bed-exchange system, the entire process becomes a breeze. For detailed information, read this documentation and follow a forum.

Simplyprint is a professional server based printer management solution targeted to printing farm, businesses running its own production and also to hobby/enthusiast users who would like to enhance their workflow. It brings a lot of functionality to your printers including remote connectivity, live monitoring, print queue and history, cloud slicer and automation.

To run your Prusa MK3/MK4 printer with SimplyPrint system, you will require a Raspberry Pi to install the software. One Raspberry Pi can be connected to multiple printers.

Simplyprint offers different subscription plans including a free one. However to run an automation feature you will need to choose the "Print Farm" plan (currently $34,99/Month - includes connection of 10 printers ! - cancel any time and 30 day money back guarantee).  

SimplyPrint offers JobOx users a discount of 25% on "Print Farm" plan for 4 month.
Discount code: jobox-25

You can find further detail on the SimplyPrint JobOx integration page here:

A more detailed instruction on how to setup SipmplyPrint in order to run with JobOx will follow shortly. For now you can contact a support team from SimplyPrint to get guidance.

Print&Go is professional server based printer management solution targeted to businesses running its own production or printing farm. To run your Prusa MK3 printer with Print&Go system, you will require an additional dedicated WiFi capable node hardware which will be provided to you by Print&Go. 

1. Already a Print&Go user?  Fill the form (https://printandgo.tech/contact-us-autoremove/) for requesting the AutoRemove Pack, needed for managing Prusa MK3 + Jobox printers in your Print&Go account.
2. You don't have a Print&Go account yet? Request a 30-day free trial here: https://printandgo.tech/contact-us-autoremove/
3. Create your printers in the "Printers" page. Create them with the "Prusa MK3 Jobox" model.
4. The AutoRemove feature (the automatic triggering of your enqueued files to the printer) is disabled by default. If your printer can activate the Autoremove, you will see a grey infinity icon.
5. Go to the Printer's page and activate the AutoRemove checkbox. There, you can modify the "AutoRemove Delay". This is the safety delay, in seconds, between the auto-retiring of the piece and the auto-starting of the next file in the queue
6. Once activated, the printer will have a green infinity icon, and the printer will auto-start the next files in the queue.
7. Upload files to Print&Go and enjoy a 24/7 production with Print&Go + Jobox!

Please note: Thanks to JobOx integration, Print&GO software is able adding the sequence for loading and ejecting to your GCODE files automatically. However, the Print&GO manager is not yet able analyzing the margins of imported files and will accept and process any GCODE, even if it is outside of allowed printing area and is not compatible for using with JobOx. We highly recommend using our dedicated JobOx profiles for your slicer in order to ensure the compatibility of your GCODE file.

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.
