If anyone is interested in beeing able to upload from arduino ide I can upload my hardware folder so you can have a look. It is pretty convenient.
I think I should mention I am on a mac btw.

Update on Printrboard problem connecting to MAC.

Symptoms: Printrboard would not connect in Repetier or Cura.  could not upload firmware and board seemed to be stuck in boot loader mode.
Actions:
1. Checked to make sure there was no jumper or solder connecting the boot pins.
2. disconnected the T-ext, the thermistor for the hot end.
3. followed PxT directions using Pre-configured Arduino to verify, compile and save Marlin.cpp.hex file in temp folder, located using Terminal on MAC.
Google: PxT Wiki Printrbot
4. drag and drop hex file on Printrboard Firmware Uploader and followed the directions carefully.
removed the jumper. disconnect usb and power.  Reconnect.
Opened Repetier and selected port: usbmodem12341 that is mapped in my MAC to usb plug in back of computer.
3DR Simple will use USB location fa13 
I have two other USB locations fa12 and fd14.
>>>>>>>>>>
USB bus fa and a USB bus fd
USB bus fa has USB hub fa1
USB bus fd has USB hub fd1
USB hub fa1 has USB location fa13 (Printrboard for 3DR Simple)
USB hub fd has USB location fd14 (Printrboard for Printrbot Simple)
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Then disconnected 3DR Simple from MAC, turned off the power to it.
powered up Printrbot Simple, connected USB.
Opened System Information. Noticed that the Printrbot Simple will use USB location fd13 (the other one uses fa13)
Opened Repetier and a new serial port was available called usbmodem11
Hurrah!
Now to make sure I always plug my USB connection into the same location.
Probably best to just leave them plugged into the back of the computer and disconnect at the Printrboard.

Yeah. I am back up and working.
Thank you for letting me rant on my problem.
Hope this helps someone else.

YES! I am definitely interested in uploading from IDE directly.

Since posting I have; if I understood correctly, discovered that my board is not an official Printrbot board and have a different bootloader so this may not apply to your board. Here it is anyway, you might consider burning a new bootloader if you think it is worth the hassle.

Inside is a teensy folder. Place it in your hardware folder and make a backup if you have one there already because there are modified files inside. There are backups of the folders containing modified files marked _bak if you want take a look at whats been changed.

After restarting arduino I got this:


And I was happy again smiling smiley

I hope it works for you too, good luck.

Aha, that is the problem. I have official Printrbot Board from Printrbot. It has their boatloader installed.

Why is the one you have in the dropbox folder different?
I would have to buy the hardware to burn a new boot loader and I have never done that before.......not sure I want to.

I have not actually tried going directly from IDE......I should try that.
