Printrbot Plus: Revision 28
Old 3D printer which never worked well. https://web.archive.org/web/20130115210644/http://printrbot.com/shop/plus/ PrintrBot Plus LCThe Printrbot PLUS is the larger printrbot kit–containing an 8x8x8 build volume, laser cut birch construction, an assembled Ubis hot end, and 12mm Z-axis rods in an all-in-one kit. This kit also includes 1 lb of ABS filament. This kit includes everything you need to build the printrbot PLUS:

The Getting Started Guide says that all Printrbots currently ship with 0.4mm nozzles. infoMost of information about it vanished from internet so here is some overview: Rev.B https://github.com/Printrbot/printrboard/releases/tag/revB serial[Sun Mar 18 08:23:50 2018] usb 2-4.4: new full-speed USB device number 61 using xhci_hcd [Sun Mar 18 08:23:50 2018] usb 2-4.4: New USB device found, idVendor=16c0, idProduct=0483 [Sun Mar 18 08:23:50 2018] usb 2-4.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [Sun Mar 18 08:23:50 2018] usb 2-4.4: Product: USB Serial [Sun Mar 18 08:23:50 2018] usb 2-4.4: Manufacturer: Teensyduino [Sun Mar 18 08:23:50 2018] usb 2-4.4: SerialNumber: 12345 [Sun Mar 18 08:23:50 2018] cdc_acm 2-4.4:1.0: ttyACM0: USB ACM device dpavlin@nuc:~$ microcom p /dev/ttyACM0 connected to /dev/ttyACM0 Escape character: Ctrl\ Type the escape character to get to the prompt. start echo:PowerUp Brown out Reset Marlin: 1.0.0 RC2 echo: Last Updated: 2012-02-25 | Author: erik echo: Free Memory: 4907 Pla echo:SD init fail workDir open failed echo:Unknown command:"echo" ok echo:Unknown command:"SD init fail" ok echo:Unknown command:"workDir open failed" ok settingshttps://github.com/Printrbot/Marlin M501 echo:Stored settings retreived: echo:Steps per unit: echo: M92 X62.11 Y64.67 Z2272.72 E536.00 echo:Maximum feedrates (mm/s): echo: M203 X60.00 Y60.00 Z2.00 E14.00 echo:Maximum Acceleration (mm/s2): echo: M201 X2000 Y2000 Z30 E10000 echo:Acceleration: S=acceleration, T=retract acceleration echo: M204 S3000.00 T3000.00 echo:Advanced variables: S=Min feedrate (mm/s), T=Min travel feedrate (mm/s), B=minimum segment time (ms), X=maximum xY jerk (mm/s), Z=maximum Z jerk (mm/s) echo: M205 S0.00 T0.00 B20000 X20.00 Z0.40 E5.00 echo:PID settings: echo: M301 P22.20 I1.08 D114.00 M115 FIRMWARE_NAME:Marlin V1; Sprinter/grbl mashup for gen6 FIRMWARE_URL:http://www.mendel-parts.com PROTOCOL_VERSION:1.0 MACHINE_TYPE:Mendel EXTRUDER_COUNT:1 software bed levelerschematicsPrintrboard_RevB_Schematic150.pngPrintrboard-schematics.pdf Marlindpavlin@nuc:/nuc/PrintrBot$ git clone https://github.com/MarlinFirmware/Marlin dpavlin@nuc:/nuc/PrintrBot$ cd Marlin/ dpavlin@nuc:/nuc/PrintrBot/Marlin$ platformio run -e printrboard dfu modeopen boot jumper, press button

unlock chip using flipIt seems that chip is protected. However, trying to erase and program it did destry data in it (expect bootloader) for some reason, and it seem that dfu-programmer doesn't know how to work with protection features. So, next step is to try atmel's flip under linux but this also doesn't work well.
