Can you post a close up picture of the Z48 controller so I can check out the wiring because this is nearly always the problem. See if you can include the receiver in the same shot. I have attended a number of robot workshops where we have had pupils building the Z48 Super Antweights and every fault was wiring that was easily corrected once identified. The most common problem was the RC lead incorrect.

Hi Paul,
Here are a couple of photos of the board and reciever.
Thanks

Hi Will,
The PCB end looks fine but I cannot be sure of the receiver end. Can you just check that (looking at the photo) the top pins are 0V, middle pins are +5V and the lower pins are the signal ones. One way of telling this is you may be able to see a pcb track that links all of the top pins together and another track that links all of the middle pins together. What make of receiver is it?
Also check that you have the jumper in position (see step 7 in the Super antweight instructions). Other things to check are removing one of the connections from the receiver and putting a servo on there just to prove the radio transmitter and receiver.
Check your motor connections, check you have a healthy 4.8V connected to the receiver battery connection.
Let us know your results and hopefully we can sort it from there. It is highly unlikley there is a controller fault as they are all tested before leaving us.
Regards

Hi,
i have checked that the reciever leads are plugged in correctly ( 0v,+5v and signal) and still nothing. I have even tried with my futaba R147F reciever from the featherweight but it still doesn't move.
the batteries i have used for testing are a fully charged AA futaba Rx pack.
And the reciever in the photo is a GWS 6 channel 40mhz one.
Thanks

Will,
Did you try the servo test? |

Hi,
I have just tried the servo and the servos work fine. Immediately after I plugged the board back in and still nothing.
Thanks

Will,
Okay, send it back to us and we will check it out. If it is faulty we will of course refund your postage and send out a replacement.

Will,
I personally tested it on our demo Z48 Super antweight and it performed without fault. This suggests that the fault is some where in your set-up.
Does anything get warm on the controller?
Do you have a voltmeter that you can check the voltage on the controller - you should have 5V between the red +ve and black -ve wires and also between the orange +ve and grey -ve wires (these are the wires from the receiver).
