I downgraded ReplicatorG to 0024 and the Firmware to 2.81 per your suggestion and now the machine loses the value from the temperature sensor. Please provide troubleshooting steps.

1. Make sure you have the whiteAnt configuration files correctly placed into your ReplicatorG installation folders 2. Make sure your 12v high amperage power supply (preferably 9-14 amps, but no less than 6 amps) is connected and turned on, and then plug the USB cable into the Arduino 3. Open ReplicatorG 4. Under the "Machine" menu, choose the "Driver" sub-menu, then select "whiteAnt" 5. Under the "Machine" menu, choose the "Serial Port" sub-menu, then select COM port for the Arduino, or re-scan if no ports are showing 6. Click the connect button 7. Under the "Machine" menu, choose the "Upload new Firmware" 8. In the new windows, select the "MakerBot Motherboard v2.X (Gen4) with Mega 2560" 9. Then in next window select "v2.81" 10. In next window. select the appropriate COM Port 11. Then in the next window select upload 12. Once complete, you should get a popup that states, "Firmware update succeeded!", click "OK" 13. Unplug the USB cable from the Arduino, and plug it into the Extruder Controller board 14. Under the "Machine" menu, choose the "Serial Port" sub-menu, then select COM port for the Extruder Controller, or re-scan if no ports are showing 15. Click the connect button 16. Under the "Machine" menu, choose the "Upload new Firmware" 17. In the new windows, select the "Extruder Controller v3.X with ATMega168 (older)" 18. Then in next window select "v2.8" 19. In next window. select the appropriate COM Port 20. Then in the next window select upload 21. Once complete, you should get a popup that states, "Firmware update succeeded!", click "OK" If you followed these steps exactly, please try to redo them a second time to allow for bad data transfer. Also, verify the amperage output of your power supply again. If this still does not resolve the issue, please call us for more assistance.
