Cicatrix Build Diary

Re: Cicatrix Build Diary

I had considered Eric Jr. but was opening the floor up to other people too. That could be another interesting way to look at it Jamie, Will be interesting to see qhqt springs up from that.

Wasn't expecting to tell anyone about it so didn't think it would become important, but it came up in the general flow of the build thread. It won't be soon anyway so plenty of time to look for some ideas, anyones suggestions would be gratefully received

Re: Cicatrix Build Diary

Also forgot to add that to the thread that both Daiske and the team Battle Rat have both found new homes respectively.

Happy to see them both find loving homes and even more happy that Daiske hasn't been broken up into its constituent parts and from what I have heard will be working for a great cause.

Re: Cicatrix Build Diary

Finished the rewiring after getting hold of more connectors today.

I think the problem has been the XXL because it is still not functioning properly. Tried to demonstrate it with a video.

The XL is pink/red and the XXL is green:

apart for the problem its looking great!

Re: Cicatrix Build Diary

From that it definitely looks like the XXL. We thought it was currently limiting at first, but the fact that the XL isn't suffering from the same issue despite being rated for only half the current handling capacity suggests that isn't the case.

Can't really offer any words of wisdom beyond that I'm afraid, apart from maybe getting in touch with Robot Power. But then, it's a modified XXL rather than the official RP XXL isn't it? Dunno how much help they'd be willing to provide in that case

Re: 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

Re: Cicatrix Build Diary

Have you checked the calibration on the XXL?

[Anttazz]

Re: Cicatrix Build Diary

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.

Re: Cicatrix Build Diary

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?

Re: Cicatrix Build Diary

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.

Re: Cicatrix Build Diary

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.

Re: Cicatrix Build Diary

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.

Re: Cicatrix Build Diary

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)

Re: Cicatrix Build Diary

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.

Re: Cicatrix Build Diary

I can't think what the problem is. You had it running at the air museum didn't you ?

I would suggest getting Rick Maas to look it over.
