This is the new updated Printrboard version F6 with the beefy USB-B connector instead of the original mini-USB. The USB-B connector is the type found on many business class paper printers which is a more reliable long term USB cable connector. The original mini USB connector could find itself getting ripped off the board if the USB cable got snagged on something while moving the printer. Because of this larger connector the access hole in your printer for the cable will likely have to be enlarged. This can be done by using a file or nibbler tool to remove excess material from the printer case.

This board should be usable on most all models of Printrbots as a replacement control board. (Does NOT directly replace the G2 mother board found on the Printrbot Pro. We are working to provide an adapter for this solution..) This version adds a second fan. The first fan cools the printed part while the second fan is programmed to turn on and cool the hot end when its temperature is above 50C. This board is pre-loaded with the Printrbot Simple Metal Marlin firmware installed and tested. Bed size and other parameters can be modified using M-codes and saved in EEPROM. Please see RepRap.com for G and M codes and their usage. Please see the additional information below for more details.

Special Notice on future availability of this version of the product

When the current supply of these boards is exhausted we may not continue to make this same revision available. We are currently looking at other possible boards with newer technology that could provide the same or a higher level of user experience. Board mounting changes and adapter cables might be necessary to get to a plug and play level. We are looking to provide our customers with the best user experience possible with their 3D printers. After a complete evaluation of possible solutions we might just come back to this USB-B revision of the board as it has been extremely reliable. We will keep you posted on our evaluation.

This board should be usable on all models of Printrbots as a replacement control board. Some models may require setting new EEPROM values for such functions as bed size. This version is designed to interface with a proximity type sensor on the Z-Stop. If using a mechanical switch instead of a proximity type sensor, then a 1000 ohm resistor must be connected between pin 1 and pin 2 on the Z-Stop connector. Pin 1 is on the Z-Stop connector end next to the EXP1 header pins. Pin 2 is the middle pin on the Z-Stop connector. This version board also adds a second fan. Fan1 cools the printed part while fan2 is programmed to turn on and cool the hot end when its temperature is above 50C and off when it drops below 50C. This board is flashed with the Printrbot Simple Metal Marlin firmware installed and tested. Bed size and other parameters can be modified using M-codes and saved in EEPROM. Please see RepRap.org and

The processor chip Atmel AT90USB1286 has the factory boot loader installed which requires the Atmel (now Microchip) 'FLIP' utility to flash the firmware into it. Arduino version 1.8.5 with the latest Marlin code will flash the hex file using the FLIP utility. As shipped from Ubis Technology, LLC the board can flash new firmware using this method. It has been tested on a Windows 10 PC laptop with this method. As of this time we have not tested it to flash new firmware with a MAC PC or Linux PC. A search on the web may be helpful to find support for these cases. Please see the additional information below for more details.

Caution: An ISP (In Circuit Programmer) type programmer such as an AVRISP, or an Ardunio made to look like one, will erase the factory boot loader when programming new firmware. This makes the FLIP software method of using the USB cable unusable because there is now no boot loader. Unless the factory boot loader or another boot loader is programmed back into it from that point forward an ISP type programmer must always be used to load new firmware. Fuse settings must be correctly set as well for different boot loaders. Please check back for more updates on programming new firmware as we are able to verify the results.

NOTE: Never plug or unplug any cables, especially the stepper motor cables while power is applied to the board. This can cause destructive surge currents to permanently damage the circuitry. Always apply power only after all connections are correctly made. Remove power first before removing any other connectors. Also manually back driving any of the stepper motors repeatedly while power is off can induce significant currents that can damage the stepper drivers. Avoid fast manual movements of pushing the print bed or extruder travel around. If done, do it slowly and not constant repeating.
