I'm running a 12 volt 3 amp power supply. Then I have a 12 volt to 6 volt DC step-down to power my EZ-B4 and servos. After the robot runs a little while sometimes the servos stop responding. But most often If I run a script to put the robots arm on its hip, sometimes it will work. Other times the arms will start to move and then the EZ-B4 will disconnect and then reboot.
I have also seen that after running a while the servos in the arms will start to run slow and not quite make it to there assigned spot. While the servos in the neck keep right on going like normal.
So I was thinking we did not have enough AMPS for all the servos. See I have 2 servos in each shoulder, one servo in the elbow, two servos in the wrist and one in the hand for a total of 6 servos in each arm. + 2 servos in the neck.
Test 1 I started to look at the power supply. Maybe we do not have enough AMPS. So I grabbed one of R2D2's 12 volt 18 amp hour battery. R2 was not vary amused to see one of his battery's wandering off. While the servos ran a tad bit faster I soon ran into the same problems.
Any ideas? confused
You can use this to bypass the ezb for power... Cheaper than @Dave's option (if you have a adequate power supply and/or battery)... It supports up to 8 servos...Servo power board
@Josh also has a great option too with his 3amp inline variable voltage regulators....
I'll definitely be getting a handful of Josh's regulators.
Hi all, sorry i am a noob at this, it's my first time.
My problem is that my ez-b 4 is disconnecting, i have looked into nearly all the threads here and have upgraded to a lipo battery 2500mah so more than sufficiant power. The strange thing is that if i open a new project the board connects fine and never cuts off, but when i load the JD project and try to connect it gives me the following:
Attempting connection on 192.168.1.54:23 Connected to 192.168.1.54:23 Reports EZB v4 OS With Comm 1 EZ-B v4 ID: 67-50-0-0-46-255-57-59-54-38-38-38 Setting battery monitor voltage: 7 Setting battery protection: True Setting i2c rate: 300000 EZ-B voltage is 8.184497646 EZ-B temperature is 24.44489368264605312C Connected Comm Err: System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at EZ_B.EZB.M3jweGrVXK(Int32 , Byte[] cmdData) BbytesToExpect: 2

Can someone please help me out i am really giving up here it has been 3 days now stress

This is the battery i am usingI am on Windows 10 ent. 64 bit 64 gb Ram no antivirus running and firewall disabled
It isn't a battery problem. It is an I2C problem.
Check the cable to the JD Eyes and make sure it has a good connection.
Find the JD-No Eyes sample project and try that (or just try a connection with no project loaded).
If any I2C object tries to initialize and can't find the device, the EZ-B will lock up and disconnect.

I'm guessing due to the strange 3rd party battery that you 3D printed a jd and don't have the rgb eyes.
Remove the rgb animator from the project before connecting to the ezb.
Hi guys and thanks for your help, i am sorry i opened another thread on this topic but as i said i am really new at this and new to the forum so when it sent me a mail that i had helped another member well i guessed it was the wrong place to post. I had already loaded the no rgb project but still had the same problem. I think in the mean time i have found out the problem. i have a shorted servo. i disconnected it resetted everything and it seems to move without any problem.
Once again thanks for the help and again sorry for the double thread
