Installed the mod with light today. Works perfect. Great addition to a already great game. Thanks for making this possible.

Setting difficulty for chest MB too easy? No need to hit targets after first lock?

Balls seem magnetised.
The release mech lid on the left of the chest doesn’t seem to open far enough. You might need to bend/adjust some metal parts there.
The chest not opening full: it seems that the initial pull down from the rod doesn’t do anything. That might mean that the first 0,5 cm pulling down of the rod doesn’t “touch” the tab of the lid at the top. Solution: mount the nut lower on the rod or make the rod shorter.

Side notes: your lid closes very fast. It looks better (to me) when it closes and open slowly. This is adjustable.
Second: your light seems to pulse, you choose a purple color and the brightness is set to low. All this can be adjusted.
Good luck.

Some photos to show the nut on my rod. I can adjust the level of the nut. If I lower it’s position the chest will open further, since the nut will pull down the tab sooner and therefore open the chest lid more.
And a photo of the position of the chest ball release tab.

I like the way mine looks and the way it works.

The chest lid does not open anymore. The UP-switch is working. The DOWN-switch doesn’t register in test. I believe this is normal since it is an extra switch.
The motor finds a rest position once I turn the Wheel a bit. But the wheel does not turn when the UP-switch is engaged.
Any advice?

Game off and on: works again!!!

My chest opens ok, but doesn’t close at all or just about 0,5 cm. The coil works and the fork moves up and down ad it should. In test the forks mech tests ok.
I re-adjusted the rod. But the problem is sometimes gone but comes back after a few up and down cycles.
Any advice on how to solve this? I now have a unlit open chest when it is supposed to be closed and unlit.

#1315 1 year ago

I removed the rod from the servo: only movement to open the chest, no movement in the other direction (to close).
Any thoughts anyone?

#1317 1 year ago

I already replaced the switch that is attached to the mod: no difference.
The regular switch that detects the “up” position works fine.
I believe the servo is 50% broken: it only moves in 1 direction. Or the program is partially malfunctioning.
What is the servo part number?
How can I re-install the software on this mod?

Replaced servo: problem solved.
