Ez-B Communication Error - Flaky Connection?

Product - Revolution:SIX

Product is in brand new condition. We took the plastic off the box this morning (it was supposed to be a Christmas gift for our son). We read through the online getting-started tutorial(s) and are now trying to setup the robot.

When we we turn on the power the servo motors twitch, as expected, but the EZ-B says "communication error" repeatedly.

When I apply downward pressure to the EZ-B I hear a start-up chime, and a blue light begins to flash. Then I can see the EZ-B WIFI connection from my computer and connect to it. I can correctly connect to the EZ-B from the builder software.

However, as soon as I release the downward pressure on the EZ-B the wifi connection disappears.

The EZ-B seems quite loose in the base plate. I can rotate it horizontally by a small amount, it's definitely not snug. Is this a QC issue? Again, product is in new condition. Two adults attempted to assemble this. Nothing was dropped or treated roughly.

The question to ask is if your power led goes out when "no pressure is applied". Because this may entirely be an issue with the computer wifi and virus scanner software or firewall.

The led in the lower left quadrant goes out when I stop pressing down. There is a blue led in the upper left quadrant that is always on when the power switch is turned on.

Does the ezb make a chime when the power is turned on?

If the blue led is always on, then that means it has power. The led requires power to glow, much like the lights in your home. So that's good news - it rules out any power related concerns. Additionally, the fitment of the dagacon shell vs roli or other shells isn't an issue. Each shell fits the ezb slightly tighter or looser by design.

No, the EZ-B doesn't chime when the power is turned on. A voice says "communication error". However, if I apply pressure, I do hear the chime and the blinking blue LED in the lower left quadrant turns on. At this point the "communication error" warning goes away, and I can connect to the wifi.

If I release the pressure, the lower left led goes away and so does the wifi connection.

I have a feeling one of two things has happened during shipping.

  1. the connector that connects the top and bottom pcb within the ezb has vibrated loose. The ezb would need to be opened with 4 philips head screw driver and pressed by hand back together.

Or

  1. the magnets within the ezb shell have vibrated loose and need to either be removed entirely or re-glued with a super glue. There's no reason they couldn't be entirely removed for convenience to get up and running quicker.

Thanks for the tips - we're out of town for a few days so it will be a few days before I can try these out and update the thread.

Hello again,

Today we took apart the ez-b shell as suggested. We see two magnets in the lower shell, neither of which are loose.

We tried pressing the top and bottom pcb boards together (they already seemed very tight) and re-assembling, but the issue was not resolved.

Then we took off the upper part of the ez-b shell, turned on the power and tried pressing on the top board to get the led light to blink (and chime). Pressing on the upper right corner of the board is the most effective. Pressing on the center works as well, but more force is required.

Attached are a few pictures of the upper-right corner of the the ez-b. The bottom plastic screw post has some damage, and there is a connector pin pointed horizontal. Is that normal? Or has the pin been bent?

Thanks, Rhyan
