Topic: Alpenrost adjusting (4 msgs / 179 lines)
1) From: Adam Jahiel
Thanks for all the help so far...  I ordered my torx security bits and
opened up the bottom of the alp. I pulled out the circuit board a bit.
Looking at it from the bottom, as in how it looks when you just take the
cover off,  I see two white pitch-pots, or whatever they are called. If I
understand correctly, the one towards the middle is what I want to turn, and
I want to turn it counterclockwise to up my heat.  What kind of a tool do
you use to turn it? A big enough phillips to grab the saoft white platic and
turn? How tight are these things? I gave mine a little turn, but I could not
tell if it was turning, or if it was just my screwdriver slipping on the
plasctic.
I'm sure it is not rocket science, but since I have a habit of over-doing
everything, I thought I would stop, write this, and proceed after further
instruction.   It's not really my nature but coffee is at stake here....

This is the instructions Cris Beck posted:
1: lay Alp on it's back (lid hinges down).  Remove bean carrier first 
though..don't want it rattling around.
2: Remove two screws in small access panel  on the bottom (ventilated, =
easy 
to find)
3: Pull circuit board out a bit.
4: On the upper right hand corner, top of circuit board there are two =
white 
cloth covered wires, they have small spade connectors that are soldered 
onto terminals.  Attache ohmmeter to those (don't remember the polarity, =
in 
the next steps if it reads 0 ohms, swap).  Set ohmmeter to lowest =
setting 
(unless it's below 25ohms).
5: There are two trim pots accessible through holes from the bottom of =
the 
board.  The one at the top appears to adjust the time of the 'bean dump' =
process (found out after I tweaked it).  The one nearest the center of =
the 
board adjusts the temperature.
6: Make sure there's nothing flammible touching the top/sides/etc...
7: Turn on Alp.  Check resistance, it should start rising pretty =
quickly.  
If it doesn't reverse polarity.
8: Mine got to 25ohms and then you could tell the heater cycled, and it 
just hung around 25ohms.
9: Turn the pot (might have to remove the gunk they used to sorta lock =
it 
down) counterclockwise (worked for me).
I left mine at 29ohms and roasted 8oz of tanzanian peaberry in 
approximately 16 minutes to what I would call a city roast.
Might need to tweak it down just a bit, but it's much better now!
As alwasy YMMV, do this at your own risk...voids warranty....yadda =
yadda...

Adam, at this point you are way out of your depth, and are in significant
danger of destroying your Alp and any possible warrantee.  Find yourself a
twidget friend, and have him help you.

Yeah, but he doesn't know what a "pot" looks like.  He thinks he's looking
for a "pitch pot."  Danger Will Robinson.
