Connectors touching back of board and blocking holes


#1

The long strap connectors are touching the back of the board, and if you put pieces on 2 specific pegs on either side, they get caught up when they try to rotate. The kind folks at TT are sending new connectors in case they are bowed, but I don’t think that is it. Is your board ever so slightly bowed? Anyone else with this issue?

ETA: Just found this post that describes the same issue. Bit can not move in one place

I’ve noticed the back boards warp slightly if left in the stands for more than a day or two, which impairs ball flow. I have to leave them face down on a flat surface, with a weight on them to get them flat again

We had the same problem; our solution was to place some spacers between the board and the connectors, just enough to lift the connectors away from the holes a smidge.


We also had problems with the supports sliding a little on the board. We used the same spacers to create a more positive space for the supports.
Perhaps the next iteration of TT will include slight improvements to this; meanwhile, it’s not too hard to hack a solution.

Hi MichelleSherer,

I’m actually working on solving this problem right now. I think we’ll end up remaking the mold for the board and switching to a different type of plastic that doesn’t shrink so much as it cools. In the meantime, I think the solutions above are good. When I run across a board that has this problem, I usually take the long connectors off the back and bend them a bit so they match the curvature of the board. Since you have more connectors coming in the mail, I guess you don’t have to worry about breaking them.

Hope that helps!

Hi, Paul and Michelle.

Introduction - I’m a physics and IT teacher in Melbourne, Australia and working at Lauriston Girls’ School.

Just got my TT out of the box and reached Challenge 3 when I hit the same problem. Second green ramp from the bottom fouls against the black connector rod. A bit annoying so early into TT but it looks like your support community is an active one.

What is the best fix, do you think? I can bend the connector rod but I don’t want to risk breaking it.

Cheers

Paul

The replacement rods they sent fixed the problem!

Hi,

I resolved the problem on my board by taping two small pieces of foamboard under the rod at the top and bottom. This holds the rod away from the actuator that protrude through the board. Now works fine.

Regards,

Doug

Thanks, Doug. I think I’ll go the same way. I gave a rod a bit of a Ben but it might straighten up over time.

Cheers from Melbourne

That’s great to hear. So I guess in your case, it wasn’t the board, it was that the connectors weren’t straight. Good to know. Thanks for posting!
