Cicatrix Build Diary

Thats the same conclusion I came to, perhaps I should have tried that test sooner than now.

I'd have to ask David Weston about that Jamie, I cant even tell by looking at it as I have never another XXL so nothing to compare it to. Hopefully he'll read this and reply but if not i'll send him a PM about it. Its also had the terminals torn from the board so its not exactly a showroom model even if it is a real XXL

.

If any events do spring up in the near future, however doubtful that may be, at least the performance will be slightly improved from how it was at RL Edinburgh, mainly because the XL is doing all the work though. Hopefully David/RL will be able to help though

Have you checked the calibration on the XXL?

**Anttazz** · 7th August 2011, 19:30

I forgot to do that, so I just tried it and the XXL is now not playing at all. Will try to work out why that might be tomorrow but i'm getting a bit too annoyed with it today so i'm going to give in.

No joy today either, the XXL is just clicking and not responding at all to any input at all. Just seems to make the motors click over and over again while the XL works perfectly. Not sure how to fix it?

What BEC are you using? The ones built into the esc? ... Might be worth disconnecting your XL (front half of the robot) and seeing if just the rear XXL will drive independent of the front... If it does I'd suggest cutting both BEC links and trying the setup with a fully charged RX pack.... Failing that contact rick maas... He's our local robotpower repair guy, he's re-built and customised the sidewinder in 540 for me and repaired the XXL in 360 for me before at a really good price.

I'm using an external Turnigy BEC and both BEC wires have been cut on the ESC's. I'll try disconnecting the XL and see if the XXL can drive the rear motors without anything else being connected and see what happens there.

Right, I think its definitely busted, took a video of what its doing.

I did as Dave suggested, disconnected all of the XL/front half of the robot and that is the outcome, it just seems to be clicking repeatedly. It does this all the time, with or without the calibration jumper on. Isn't responding to any signals, that is all it does.

From the instruction manual:
Slow blink - searching for required radio channels especially at startup

I take it your radio etc is working fine? Tried it with a different radio system or an rx battery instead of a BEC? All the receiver leads on the Scorpion still properly connected? (just to definitely rule out everything else)

It might be something to do with my dodgey soldering, but I can't see any problems other than that. The clicking is it moving the motors very slightly although you can't really see that in the video.

I don't have an rx battery, but I did try it using the XL's BEC and got the same result. As for the radio, I was using it on Daiske yesterday and it was working fine and also works fine on the XL when they are both wired up. As for the receiver wires I haven't checked them but I will give them a look over.
