 The vending barely breaks even, we don't make a profit from sales.
-Web interface to use SOGs: https://vending.waw.hackerspace.pl/ . Acquire SOGs by talking to other members of the hackerspace.
+===== How to use =====
-===== Hardware =====
+Log into [[https://vending.waw.hackerspace.pl/]] using your SSO account. The interface shows you how much credit You have. The currency is SOGs - acquire more by talking to other members of the Hackerspace.
+Choose your Caffeine Spice Type, click "begin transaction" on the web interface. Transaction will expire after some time (how long?), so choose wisely. Enter the number on the keypad on the machine (physical machine, not the web).
+Machine will dispense your chosen Caffeine Spice Type. SOGs will be withdrawn from your account. Enjoy!
+Some bottles are reusable, so don't throw them away.
+===== Troubleshooting =====
+Clean the heat exchange/cooling module every half a year.
+If it's not working (turned off, no lights, etc.) check if it's connected to power in the WC (socket above the sink). If it is, try to disconnect and connect it.
+If it's working in the test mode but doesn't in the regular sales mode, enter the menu and press C+E multiple times.
+"FAULT CONVEYOR?FF" and Test/Normal vend mode doesn't work? Go to CHECK - it should list *some* problem. You need to acknowledge it, I think using E and C+E? Not sure. But this fixed it! Check screen should print "CHECK OK! NO PROBLEMS" afterwards and everything should be back to normal.

+==== Service Log ====
+-01-27 - around 2026-01-21 Y-axis motor started loosing steps when traveling above first shelf. Turns out a counterbalance line slipped off counterbalance pulley, rubbing over its axle. Steel line is supposed to be encased in rubber - but it's has worn off ~50% off its length. Should probably be replaced at some point.
+-01-27 - "XOffset/YOffset output" parameter in Robimator → Configure (remember to "Transmit List"!) changed from +3/+0 to -12/+7 and now vends succeed on first try!
-===== Costs & Clownfunding =====
+-04-16 - as has been fortold in January: the counterbalance line's finally given up. It broke. It's been replaced with a line without rubber encasing, so it should be considered a temporary measure.  Old counterbalance line: 0,8 mm, about 1050 mm length (hard to measure, the line was in two parts) New counterbalance line: 1,0 mm, about 1050 mm length. At the ends an electrical bitsy-bit's been used, as in the picture.
-Acquiring the vending cost us the following:
+Markings on the bitsy-bit: [5,5 - 6 / 12 10], encased in yellow rubber. The rubber's been removed before installation at the end of the line.

-q3k would still like to get 405.07 contributed from someone so that he doesn't spend more than 1000PLN on this.
