Step 1

After you remove your ORION, set the parts aside like shown.

Step 2

Install the SD card in the left hand side with the label facing towards the back of the panel as shown in the photo.

Step 3

Remove the left side cover using the two black thumb screws.

Step 4

Install the power cable by passing it through the hole in the bottom of the machine and then insert it into the connector as shown.
Select your input power on the switch below the plug in the photo. The machine comes set for US based 110 volt power, but the power supply can be switched to 220 as well.

Step 5

Replace the side panel as shown. Make sure to get the slot end towards the back and top of the machine.

Step 6

Install the spool holders in the slots as shown.  For small diameter spools only one support is necessary, for standard 1KG spools both are needed.

Step 7

Install the USB cable by removing the front panel using the two thumb screws on each side of the panel.  You can see the USB jack on the left side of the electronics board.

Step 8

Pass the end of the USB cable up from the bottom thru the hole underneath the jack, then re-install the front panel by inserting the bottom first into the tabs and pushing up and back.

Step 9

Install your filament spool on the supports and pass the end through the slot on the support panel, down and through the slot on the extruder panel as shown below.

Step 10

Straighten the end of the filament so it can pass through the extruder without getting caught.  Now press the red lever on the extruder with your thumb and thread the filament behind the red lever and up through the extruder until you see it in the tube coming out of the fitting on top.

Step 11

Now you can turn the white gear by hand to feed the filament up to the hot end, but stop short of entering the fitting so you can pre-heat the machine later without risking burning the filament while it sits inside the hot-end.

Step 12

Using the three photos below, slide the arms up, one at a time and move the platform down below the carriages to put it in to print position.  The purpose of having it 'inverted' is to safeguard against damage during transportation and shipping.

Step 13

Now go ahead and plug the machine in to a grounded outlet and turn the power switch on the front panel on.  The LCD should light up and look like the photo below.

Step 14

Press in on the knob once and turn to select Quick Settings as shown below.

Step 15

Turn the knob to select Home All and press in to select.  
Your New ORION is alive and ready to start printing.

Step 16

Now using the selector knob, scroll down to SD Card and click to select.

Step 17

Using the photos below for reference choose Print File, then choose GCode folder and in there you will find three ready to run prints.  These 3 prints are set up for ABS material and are what are printed on your machine to test it before we shipped it to you.  They are set too hot to print PLA with.  You may download all three files and prepare them for PLA.

Step 18

Install Repetier Host software by clicking HERE and choosing your operating system.  Follow the on-screen instructions to set up the software and install it.  It's handy to have a short-cut on your desktop/quick-start bar to get to it faster.

Step 19

Install the USB Driver (Windows only) by clicking HERE to download the driver for the machine.  
For Mac/Linux machines, it will automatically use the dev/tty driver path.
For Windows users, extract the zip file you download from above and then plug the USB cable in to your computer.  Windows will fail to recognize the device, as it is not a signed windows official driver.  Go to Computer, right click and choose properties, then device manager, and scroll down to the Unrecognised device labelled "RAMBo", right click and choose update driver software.  Choose Browse for driver software, then Let Me Pick, then Have Disk, and point to the RAMBo.inf file in the extracted folder you downloaded.  It will warn you that it is not a signed driver, and click install anyway .  Once the driver finishes installing, close the driver install windows and unplug the USB cable, then plug it back in. 

Step 20

Now start Repetier Host software.  Once it loads, go to Config>Printer Settings.  Choose the COM port that was created when you installed the RAMBo USB Driver in the first Connection Tab, and verify that the baud rate is set to 250000.  Next click on the Printer Tab at the top.  Set the Travel feed rate and Z axis feed rate to 3000, Default Extruder Temperature to 150, Default Heated Bed Temperature to 70 and make sure "Go To Park Position after job/kill is UNCHECKED.  Now click on the Printer Shape tab at the top and choose Rostock Printer (circular print shape) from the drop down.  For the Home X choose 0, same for Home Y, and Home Z needs to be set to "Max".  Below, set the printable radius to 75 and the printable height to 250.
(for Mac/Linux, it is diameter not radius, so set it to 150)

Step 21

Now click on the Apply button and you should now see the screen display a round table in the display window.  Make sure the USB cable is connected and turn the power on.  Click on the Connect icon at the upper left corner of Repetier Host screen.  You should see the status in the lower section of the log window showing it is connected, and the connect button change it's text to Disconnect.  

(For Mac/Linux users press the down arrow key now to see special notes on setup.)

Mac/Linux special notes

Some Mac and Linux distros do not support the 250000 baud rate.  If you are having problems connecting to the machine in Repetier host, using the LCD control screen click and scroll down to Configuration>Baud rate and set the baud rate to 115200, then click on the back text, and scroll down to Store to EEPROM and click.  This will set your baud rate to 115200, and now go back to Repetier Host and go to Config>Printer settings and select 115200 baud rate and press Apply.

Step 22

Now lets configure Slic3r for your ORION with some default settings.  To do this, download  one of the following files

For ABS, download ORIONABS
For PLA, download  ORIONPLA

These are great starting points to get to printing parts.  While they are good general settings, different parts will require different settings.  To learn more about all the settings, we recommend experimenting with them and using Repetier Host to preview the resulting G-Code.

Step 23

After downloading the profile for your material, click on the Slic3r tab on the right side of the screen in Repetier Host.  Then, to the right of the drop down boxes, click on Configure.  This will open up Slic3r so you can specify and make new print profiles.  Once it is open, go to file>Load Config and choose the profile you just downloaded.  It will bring in the settings for each profile.  Now, click on the Print settings tab and click the disk icon to SAVE the settings.  Now, click on the filament tab, and then the save icon, and do the same for the Printer Tab.  You can now close Slic3r.  

Step 24

Now you're ready to "Slice" a part!!!

If you haven't already, you can either download an STL file form the internet from sites like REPABLES or other file sharing sites.  Go grab one now if you haven't, and click on the Object Placement tab in Repetier Host.  It will open your object and allow you to scale, rotate and position it on the virtual bed of the machine.  Once you're ready to process the file for printing, click the Slic3r tab, and at the top click on Slice with Slic3r.  This will start the program to generate the G Code for your model.  You'll notice a pop up window showing you the amount of time it has been working on the part.  When it is done it will automatically change to the G Code Viewer tab and show you a preview of your print.

Step 25

If you are ready to start printing and are connected to the machine, you can simply press the Play icon on the top of the screen and it will start sending the job to the machine.  We recommend printing form the SD card though, as USB is prone to interference which can cause issues during a print like interrupting the transfer of the file causing the print to fail.  To save the print to the SD card, you can, from the G Code Viewer tab, click the disk icon and choose where to save the file.  Note that the file format has to be 1234567.gco, no longer than 7 characters and end with the .gco file extension.  You can manually change the file extension if needed, as the default extension is .gcode, which may or may not be readable by the machine.

Step 26

To print form SD, follow the same steps as earlier in this guide.  Insert the SD card, click  from the main menu, scroll down to SD Card, select Print File, and choose your file.  Once you select the file, it will start printing.  It may take some time to begin, as it has to heat the bed, if called for, and then home the machine so it knows where it is, and then finally it heats the hot-end to melt the plastic.  To speed this up, there are some handy Pre-Heat commands on the LCD controller found in the Quick Settings menu for both ABS and PLA.  If  you're trying out T-Glase, you can use the ABS settings, they work pretty well.

Press Down to see troubleshooting tips.

Prints do not stick during the first layer.

  • Nozzle too high off the table.

You can adjust the initial Z height by adjusting the 3 Phillips screws on the top of the carriages by turning them IN to raise the nozzle off the bed, and turning them OUT to lower the nozzle.  Remember to home the machine after each adjustment, and turn all 3 equally.
  • Heated bed not hot enough.

You can manually override the bed temp on the LCD panel by clicking from the home screen and scrolling down to Extruder, click, then choose the bed temp and adjust from there.
  • Heated glass plate needs cleaning.

You can simply wash the glass plate with warm soapy water and allow to dry thoroughly before using.  Make sure the glass is cool before removing it from the ORION!

Step 27

Your ORION comes with a 220mm diameter round borosilicate glass high temp/high strength glass build plate.  For printing PLA, a super clean glass plate can work really well.  However, we have a great low cost trick to help your prints stick well.  All purpose glue stick, especially the washable kind that goes on purple and dries clear.  With the glass cool and clean, apply a thin coating to the glass and then heat the bed to cure it.  This will help with PLA, and is a MUST have trick for ABS prints.
