I'm having the following issue:

After performing all the compiling and moving over the hex file to the Lincomatic HID bootloader. I hooked up my printrboard rev e. I was able to see the comm ports on my device manager however when I apply the jumper and press the reset button I can no longer view any com ports it completely disappears. Has any had this issue?

Thx in advance for your help!

Lines 91-94 in configuration.h, I changed the bed sensor table from 6 to 1.
#define TEMP_SENSOR_0 6 //{SD Patch}
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1 //{SD Patch}

Lines 162-165 in configuration.h, I uncommented pidtempbed which gives me perfectly flat 115C with the values already in the firmware.
// If this is enabled, find your own PID constants below.
#define PIDTEMPBED
//
//#define BED_LIMIT_SWITCHING

For the ones bothered by the firmware not displaying correctly in RH:

Lines 32-34 in language.h, I have the printrboard and using 81 myself.  The firmware I have from lawsy's github doesn't have that as an option in the language tab.  I just added the extra "|| MOTHERBOARD == 81"

#elif MOTHERBOARD == 62 || MOTHERBOARD == 33 || MOTHERBOARD == 34 || MOTHERBOARD == 81        //{SD Patch}
    #define MACHINE_NAME "Solidoodle"                                    //{SD Patch}
    #define FIRMWARE_URL "http://github.com/mlaws/solidoodle2-marlin/"   //{SD Patch}

I fired up both the bed and the extruder after the bed stablilized temp.  Neither fluctuated and maintained a flat tempurature, which rules out the power supply lacking like I was previously suspecting.

I hope this can help some of you guys.  Happy Printing!

What does your pins.h file look like?

Hmmm, i only got a quick glance this morning at that tab before i left.  I'm going to research a bit about the ins and outs of what does what if i can.  The fan settings i did see were all -1.

I have a Solidoodle 3 with the rev E board.  I used 81 for the firmware per the instructions.  Regular flashing doesn't work, it doesnt seem to see a connection.

Hopefully just one of the settings in there just needs a tweak, when i get back this afternoon I'll be able to try!

Edit:
Went to check out the pins.h more clearly after having time during the day to research a bit.  These printrboards are using a slightly different pin config from teensy.  The firmware had the pin set to 22.  Reflashed it after changing to 16 and I've got over 12v!  So now I'm in business.

#define FAN_PIN            16  // Fan
// You may need to change FAN_PIN to 16 because Marlin isn't using fastio.h
// for the fan and Teensyduino uses a different pin mapping.

For future reference, I looked around to see what code output the version of the firmware but didn't notice anything.  Mine still says marlin v1 solidoodle from mendel-parts.com.  So that's not a sure fire way to check if it changed or not apparently.

After I did it the first time I went ahead and heated the hot end and tightened it a bit per the instructions, meaning the max temp in firmware must have changed to the 320 i set it for.  I didn't do anything except flash it with the bootloader, but now the gcode fan doesn't work.

When I load up RH, it shows the firmware as marlin v1 solidoodle mashup from mendel-parts.com.

I'm only getting at best 0.3v from the fan pins now which worked fine before the flash.  I've tried all kinds of combinations it would let me do with board selection and all.  I'm ending up in the same place each time.  I get no errors and everything seems to work fine.  I've been trying to get a proper reflash now for a number of hours just to regain my fan control

Any ideas?

Awesome work!

That is what I keep getting. Since I cannot find the.cpp.hex file, I decided to run ahead. When I try to upload, it ways this.

When I try SHIFT+Upload:
Binary sketch size: 48,434 bytes (of a 126,976 byte maximum)
avrdude: usbdev_open(): did not find any USB device "usb"

Chill pills are not working right now

Swift response is massively thanked

Awesome! Thanks for the swift reply!
Would aluminum foil work? If not, strip some wire and wrap it on there??

Yes that will work,

Possibly a stupid question. If so, forgive my ignorance:

Jumper. The two long pins in the center of the board, right? There seems to be a black plastic footer where the pins appear to rise out from the board. Do I take the whole thing out? Or just the plastic? Will this require a soldering iron?

So happy I found this thread!! I'm confident up to line 25, but am super scared of bricking

You jump them two pins together (line #3) and then you remove the jumper (line #25) .
hope this helps.

Awesome Jake, I'm glade you got yours to work, on your temp sensor, what did you have yours at a 1 or 6, is 6 the one i us for the sensor that comes with the hotend ?
Thanks Gary

Ok here are the steps i think i took to get this to work. 

you will need a jumper (or a way to short the boot pins)

1) unplug all connectors from the board
2) plug the USB cable into the board, then into your computer
3) put the jumper on the boot pins
4) press the reset button on the solidoodle REV-E motherboard
5) download https://github.com/mlaws/solidoodle2-ma … lin_v1.zip (and yes, this is for updating firmware on a solidoodle 3 REV-E, but the download does say "solidoodle2")
6) download http://www.reprap-usa.com/download/arduino0022.zip
7) unzip the solidoodle2-marlin-Marlin_v1.zip file
8) unzip arduino0022.zip and then open the arduino.exe file (do NOT let the software update itself)
9) once the arduino program is open click "File --> Open" and browse to the folder you unzipped to in STEP-7, open the solidoodle2-marlin-Marlin_v1 folder, then the marlin folder, then open the "marlin.pde" file
10) In Arduino click the "configuration.h" tab and change line 16 to read "#define SOLIDOODLE_VERSION 3 //{SD Patch}"
11) change line 55 to read "#define MOTHERBOARD 81 //{SD Patch}"
12) change line 113 to read "#define HEATER_0_MAXTEMP 310 //{SD Patch}"
13)  note* i didnt change the temp sensor line in the firmware because i am still using the stock thermisistor...
14) hold down the shift button and click "verify" in the upper left corner (the button looks like a play button triangle)
15) wait for compiling to finish
16) look at the output at the bottom of arduino and browse to that folder (i.e. - C:\Users\Jake\AppData\Local\Temp\build6982580482908010905.tmp\ )
17) right click and copy the "marlin.cpp.hex" file.
18) download http://blog.lincomatic.com/wp-content/u … derHID.zip
19) unzip BootloaderHID.zip and open the new folder.
20) right click in the folder you just unzipped and paste the "marlin.cpp.hex" file there.
21) hold down the shift key and right click in the white space of this unzipped folder, then click "Open command window here" from the menu
22) type "hid_bootloader_cli -mmcu=at90usb1286 -w -v marlin.cpp.hex"
23) press enter
24) wait for the process to finish and reboot the board (it should be less than 30 seconds)
25) remove the jumper from the boot pins on the board
26) replace all the cables to the board
27) enjoy your newly flashed firmware!

ps - let me know if this doesnt make sense.

Oh thank you!!! this is what I was trying to find for 2 days of searching. I am back up and running. I did a little different though. I used the firmware from:

http://www.solidoodle.com/solidoodle-mo … -firmware/

and modified the temps.
