Getting Started with the Heated Bed Upgrade on Your Simple Pro

First Step:

New Firmware - G2core170411.bin is the first release of G2 firmware that enables heat bed functionality.  For instructions on how to flash this new firmware onto your G2 Printrboard please visit here.

Note - if you purchased your Printrbot Simple Pro directly from Printrbot.com after June 13th, your Simple Pro will already have the most current firmware already installed. No need to go through the first step.

 

Second Step:

Install the Heat Bed Upgrade onto your Simple Pro. Please watch the video for instructions here.

 

Third Step:

Now download and setup your controlling software which will run your Simple Pro with Heated Bed. We recommend and have documentation for using Cura 2 software (You can also use other software such as Pronterface, Repetier, or Simplify3D to name a few.). Please visit here and scroll down to “Setting up Cura 2” for instructions.

When you reach step 6 you will need to adjust some of the information.

Be sure to select “Heated Bed”

Start Gcode: Select ALL existing text and delete it. Add the text below.

Cura 2 should look like the two screenshots below when your Simple Pro is not connected to your computer. Notice how the second screenshot, when you click on the upper right hand icon of the 3D printer that the dialog reads “No Printer Connected”.

The proper steps to get Cura 2 to identify your Simple Pro as connected is to begin with Cura 2 open on your computer. Make sure your Simple Pro is turned off as you connect it to your computer via USB-B cable. Once connected via USB-B, turn the on/off switch on the Simple Pro to On. Give Cura 2 up to 30 seconds to a minute to auto-detect and connect to the Simple Pro. Once this takes place you will see a green check mark in the icon of the 3D printer in the upper right hand corner of the window.

Click onto the icon of the 3D Printer. You will now see that the dialog reads “USB Printing”.

A great new feature of Cura 2.5, is the ability to pre-heat the heat bed on your Simple Pro.

In order to enable this you will need to go back to the main screen of Cura which will at first be automatically on “Recommended” settings. Go ahead and click “Custom”. This will show reveal a handful of sections such as Quality, Shell, Infill, etc. You will go to the section titled Material and find the field for Build Plate Temperature. You can adjust that value to the temperature required for whichever filament you are looking to print with (always refer to the manufacturers guidelines regarding filament temperatures). Once you’ve put a value into the Build Plate Temperature field, you can now navigate back to the Printing Tab and pre-heat your heat bed to the temperature identified in the previous step.

You are now ready to begin printing with your Simple Pro with Heated Bed. We recommend that as your heat bed is heating up and reaching temperature that you wipe down the PEI sheet with 91% Isopropyl Alcohol. You can find Isopropyl Alcohol at any grocery/pharmacy in the first aid section.

 

You may be asking

“Wait, can’t I just use the cloud for my new heat bed?”

The answer to your question is yes and no. Unfortunately at this time, the slicer in the cloud is not able to turn on the functionality for the heat bed on your Simple Pro. You can however use a stand alone slicing program such as Cura 2, Slic3r, or Simplify3D to slice your model with heat bed enabled, export it as a gcode file, and upload it to the cloud. If you would like to learn how to do this please visit here.

Otherwise you will need to connect your Simple Pro to your computer via USB-B cable.
