The rotator points in the opposite direction and oscillates. A spray of isopropyl alcohol through the holes may also be necessary to shift any grease on the commutator. They can often be restored to operation simply by "tickling" the brushes with the power applied by inserting a squashed wooden toothpick through the crescent shaped holes. The motors from China did not work: The motors brushes have a propensity of lifting off the commutator due to shock and vibration in transit. Use low power, shielding and grounding techniques. Run a couple of turns of the antenna, I2C and USB/RS422 cables through ferrite toroids. Add 0.1uF caps from the motor terminals to the motor chassis. Try overall-shielded cable for the I2C bus. So here are some tips for you to try: Place the sensor on the boom away from the driven elements - or better still on the lift arm. The fact is that every assembly and installation is different and we can't address every situation. We have done a lot of investigation in these areas and have a lot of feedback ranging from there is no problem at all through to unworkable situations. Transmitting as little as 10W into the antenna can lock up, reset or even fry the electronics. RFI and EMC problems: The electronics generates RF Interference, which can be heard in the receiver while tracking satellites. 
It works OK using the USB port with a Linux PC.

A work-around is to use a USB-TTL Converter connected to the TX, RX, GND and VCC pins on the Arduino and changing the code to use the Serial1 port instead of the Serial port.

Easycomm II rotator position feedback does not work on a Windows PC because of a handshaking issue when using Hamlib with the Arduino IDE USB port driver.
Gpredict does not display the rotator position on a Windows PC, but the rotator works fine. The bug has been reported, but the only solution for the time being is to use Gpredict version 1.4. It no longer gracefully handles the read error encountered by HAMLIB when polling the rotator via the USB port. Something has changed in Gpredict since version 1.4. Gpredict versions later than 1.4 crash when engaging the rotator control via HAMLIB. Some readers have re-tapped the holes to 4mm. For ease of tightening the shaft hub mount, the two small grub screws were replaced with 3mm cheese-head or cap screws. However, using a second shaft hub for the azimuth mounting is by far the best and cheapest mounting method. We have tested the following 4-screw steel shaft coupler from eBay and can report much better stability with it. It seems never tight enough: The rotator wobbles from side to side and at high elevation angles the lift arm hits the tripod upright. We have found that the original soft-brass shaft coupler used for the azimuth mounting wears out after repeated assembly/disassembly. 
All good ideas! We added Help and a Pause command.
Better serial monitor support: A help command. The sensor needs to be attached to the antenna boom and the rotator mounted on a sturdy tripod. The rotator azimuth and elevation motors just turn continuously. Cut a soft drink can for shim to pack the gap. Yes, frequently 1/4" is sold as 6mm and vice-versa. Trouble finding a suitable satellite antenna: We use the Arrow II 146/437-10W from here. Micro usb tv antenna driver#
eBay parts dead on arrival: 1 motor, 2 driver boards (reordered).Ordering the wrong parts on eBay: 2 motors (reordered).The m command does not work: The m command won't work properly until the calibration is completed.

Original version of software assumed the EEPROM was initialised.
