Printrboard G2 Getting Started Guide

Firmware: If you ordered a Printrboard G2 after 5/5/17, your board will ship with the proper firmware.  If you need to flash your G2 for any reason, click here to download .bin files.  To flash the firmware to your G2, follow the steps in this guide.

 

Install your G2 Printrboard and follow the wiring diagrams below.

Connect your Printrbot to your computer via USB B and power the bot ON.  In your Cura Control panel, select Print via USB in the bottom right corner of the screen.  You should also see a green check box indicating connection status at the top right corner of your screen.

Click Print via USB and monitor your printer.  This initial test is only to verify start movements and motor direction.  Your startup sequence should match the video below.  To stop your print, click Abort Print in the bottom right corner of your screen.

NOTE: Your Z offset is no longer calibrated.  You will need to recalibrate.  See "Next Steps" below.

    First off, awesome article. It clears everything up!!

    Will the G2Downloads.zip file be updated every time there is a new firmware, or is there a place we can go to get latest?

    Moses, there are screw terminals on the G2 similar to the F6 to receive the heat plate wires.  However, firmware is not available for heat plate functionality ...mentioned on the product page "The G2 board is capable of running a heat plate, but is not a “drop-in” replacement controller.  In other words, if you have a current Printrbot heat plate (Plus/Simple/Play w heat bed upgrade), you will lose the capability to heat your print bed with this board."

    Oh – Is there a reason why the Beef was left out of the burger? What's the purpose of an upgraded board with huge lack? Sorry I'm confused. But doesn't the new Simple Plus comes stock with the G2 board and now with heated bed? – Thanks

    Is there an "Upgrade" or better board than the F5 available?

    Update: Heated bed can now be enabled on G2.  See comments from github below.  

    For any machine with a heat bed, M100.1 ({he3e:t}) needs to be issued to enable the heat-bed temperature control.

    • If it's enabled and the heat-bed isn't connected it will cause an alarm. So the default is not enabled.
    • If it's not enabled and the heat bed is used (set to a temperature) it will cause an alarm.

     

    For more, please see Supplemental Gcode for Upgrades on Your Printrboard G2.

     

    "Is there an "Upgrade" or better board than the F5 available?"

    F6 is available in microUSB or USB B.  

    • Push-push microSD card socket
    • Independent fan ports – Control your print fan and hot end fan separately.

    For those looking to upgrade and stick w their current workflow, I would recommend F6 over G2.  

    I hope that is helpful,

    Also where do I plug in the Z-Stop, Fans etc.. This board is missing a ton of connectors. Looks like I'm missing that second Board. If there is a second board where the heck do I purchase it cause it's no where on the site. What heck?

    Now Im just baffled on what to do with the USB cable! The USB Port doesn't not fit my PLUS! I see that the Play will need to be Cut/Hacked but says nothing about the Plus. Please don't tell me I need to hack my Bot! :(

    Fear not Moses.  You can push the USB end of a USB B cable through the SD slot of the base of your Plus and "commit" the cable to the bot.  Orient the G2 w the USB B connector away from the USB and SD holes and you will have room to connect USB B.  You will have to keep that cable w that bot.

    Hey Dave! I figured out a way to have it more intergrated. 

    Going to design/3D print a plate to hold the board at a different position with a built in USB port like this https://www.digikey.com/product-detail/en/switchcraft-inc/EHUSBBAXPKG/SC2491-ND/1832374

    Keep you posted!

    So I don't see an SD card slot... I miss that Memo LOL

    Can you point to where I can find a Blueprint/Schematic of the G2 card?

    Thanks!

    Cool find Moses.  Yes, please share w others if you come up something that you like!

    Regarding SD socket, the G2 was originally designed w the Simple Pro (including touch screen) in mind.  The hub touch screen holds the SD card and delivers locally stored info to the G2 on that bot.  So, we did not use real estate for SD on the G2 because it was accounted for elsewhere.  Ultimately, we are heading to hub integration for all of our bots.  Not there yet though.

    As far as blueprints/schematics, the best I can offer is at the top of this article.

     

    thanks,

    Hey Dave, Question. The Hot End connector on the G2 is a 2 pin and I have a 4 Pin connector with two wires going into it. Do you have an adaptor or something I need to get?

    Using the Simpler bin file (G2core170411.bin) found here https://printrbot.zendesk.com/hc/en-us/articles/115000151583-Printing-via-USB-on-Cura-2-with-Your-Printrbot-Simple-Pro works like a charm every time but Im assuming I don't use the simpler bin file on a plus so when I try the one for the Plus from the top of this page - I get this Error.....

    Hi Moses, you can re-pin your existing hot end power connector and place the two wires next to each other or order this small connector.

    Either way, see an example of re-pinning wires in this video.

    thanks,

    Small detail, but try pulling the .bin out of the folder and keeping it directly on your desktop.  Then, pull the file from your desktop onto your firmware updater.

     

    thanks,
