Re: how many people have had failing jaguars

We had one die for no obvious reason today. Worked in the pits, then once we got on the field, nothing. No light, good power, good pwm. Luckily, we had a spare already mounted and wired to the distribution block.

Re: how many people have had failing jaguars

2 Regionals, 27 regular matches, and over a dozen practice matches and all three of our Jags are still running strong.

Re: how many people have had failing jaguars

854 toasted one on the practice field minutes before a match 1075 was set to play against them in Waterloo... I helped them swap it. I wanted to beat them on the field, not off it. (We did... 64-30)

Re: how many people have had failing jaguars

Ours died rather early in the build season. A stroke of luck, considering what I've been hearing and reading from other teams.

Re: how many people have had failing jaguars

We had one fail during a match at the Dallas Regional. Thankfully our design incorporates a redunant system and we were able to continue in the match with one dead speed controller!

Re: just wondering

Ours failed at Cleveland- we we pulling x amount of current through them and for some reason they would shut down. The Luminary Microsystems rep couldn't offer an explanation why. This happened twice, so we pulled them and replaced them with victors and have not had a issue since.

Talking Re: how many people have had failing jaguars

From what I understand a lot of people have been blowing up Jags this year. One cause that I heard was common was that when you sent either a 1 or -1 value from the joystick to the motor the jags would blow up. Although this was an easy problem to fix (just set the values to .99 and -.99) our team opted out of using the jags this year because this was all unknown and we figured "why not use the extra victors we have lying around while we still can."

Hope I could help

Re: how many people have had failing jaguars

Yeah, victors are smaller, and less breakable. But jags are smoother and offer so many more options.

Re: how many people have had failing jaguars

We blew out a jaguar after 5 tries using our winch to lift ourselves up.
Swapped it with a victor and no problems since then.

Do you have any explaination why, or is this just imperical data.

We dont have any explanations other than the fact that after repeated tries, no problem since, all else the same.

Re: how many people have had failing jaguars

We just blew one of our Jags about an hour ago. It started smoking, a part melted inside, and now it only drives in one direction. We'd rather not request a new one from TI, so if anyone from the GTA has a spare, we'd greatly appreciate it if you sent it our way.

Why not request one? It is simple, they ship them quickly, and want the bad one back to analyze. And no cost to your team!

Frankly, I was 'down on Jags' until I sent 2 back, and experienced their tech support.

Re: how many people have had failing jaguars

Revus - I'm not sure why you wouldn't want to send it back. They'll replace it for free with no hassle (unless you did something insane like drilled a hole through it).

Re: how many people have had failing jaguars

1075 smoked 3 Jags on ship day (Black Jags, too). Can't see any particular reason why. We're working on getting them replaced.
