much trial and error but finally got it!

Nice walkthrough ^^ Thanks for testing ;)

here's one of mine, where you build your own mechanism.

good map
first glace, very complex.
when I realised the reflector cube dropper area's only function was to respawn cubes, in order.
I tabled that & looked at exit area & the order I needed to activate everything.
then looked at symbols in 3rd chamber,
not that hard, when you don't try to sort all 3 chmbers in your head, at the same time.

very good work :)
no problems found :)
I will leave a link of one of mine, here soon.

Another great map. Interesting concept using a FIFO stack to operate a sequence. Cube delivery mechanism was awesome. Thanks and I'll see ya round the workshop.

@buff00n : Looks like the expected solution ^^ Glad it worked well for you.

The mechanism worked flawlessly for me once I had it figured out. Great ideas as always.

My "program": http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=185743527

Well, after I settled a bit, I changed my vote. But it was still frustrating.

Map updated, the main loop should be unbreakable now ^^

Here is my blind playthrough of this map. You'll find plenty of comments in the demos as you watch them. http://bisqwit.iki.fi/kala/laserprogramming-geneosis-blind-by-bisqwit.zip
TL/DR: Brilliant idea, completely ruined by physics engine randomness = frustrating map, downvote.

You can also try respawning the traveling cube each time so its alignment gets reset each time instead of getting slightly worse each time around.

Hmm well I think I could also do it with a laser for each dropper and a normal cube to cut them ^^

Just a suggestion. swap the working plane (Y as seen from the button possition) of the dropper/ faith plates and the gravbeam/ cube circuit. The relighability of the floating cube circuit drops greatly as the range from the laser recievers incresses. The little random bounce and rotation when the cube meets a light brige can ruin an other wise perfect machine. I gave up using this mechanism for important functions. At minimum distance it repeats fine 98% of the time, but sometimes that's not enough.
I'm still working on the puzzle... Nice work!

Very interesting concept, but this map is hard to solve (for me).

Orange gel is only here to make movements easier ;)
About the unused cube... I should rework this part then ^^"

Yes, I even could walk through the exit door, off course its disintegrates if you do so.
No fancy Ninja trick, just put 4 cubes on the correct place. Place portals on advance and the last cube (number 5 in sequence) on the piston platform. If you like I can upload a position screen dump of the cubes.

By the way: What is the purpose of the orange gel?

Hmmm, you had time to wolk on the transprent panels between two cubes desintegration?

Verry good, used only 4 cubes.
