I've just purchased a MDX and just wondered do you have to adjust the grinder for different beans you purchase? Am I doing something wrong?

Paul,
Every grinder needs to be adjusted, not just for each bean but for the age of the beans, the humidity in the air etc.

The MDX is a good espresso grinder (I have one among other grinders) and it is easily adjusted. There is no one setting to use, only a starting point and you adjust from there.

What troubles are you having?

Hi Paul I noticed you have posted quite a few threads about your new machines and seem to be having a hard time getting good extractions right? I am no expert but after reading your other threads and answering your previous grinder question to the best of my ability :)  "Best setting for nuavo simonelli MDX grinder". I am starting to think you may have more of a bean problem than an equipment problem. I saw that you recently bought beans from costco and are looking for some good chocolaty beans in the Seattle area. The beans from Costco are hit and miss, mostly miss IMHO. Even staleish beans can cause problems both dialing in your grinder and with extraction like horrible sour tasting fast shots and bad channeling. I would suggest buying some fresh beans ASAP it is an investment when you are just starting with a new setup but its really the only way to figure out a good baseline for grind settings, dose and technique. If you use stale beans you will end up going in circles and become more frustrated than you probably all ready are. I live in the Seattle area and have been trying out beans lately and so far I have found a few good ones. If you go to Seattle Coffee Gear in Lynnwood they have a variety of fresh beans but check the roast dates some of the coffees are not local and don't have roast dates. I like Zoka Paladino there are a couple locations one in Walingford and one in University, 12oz bags for $12.50 it is very mild flavored but not super chocolaty as far as I could taste (beginner pallet). I also have tried Middle Fork from SCG $14 for 12 oz both the espresso roast and back pedal blend and they were good in larger milk drinks but very strong and smokey as shots, not my preference. My absolute favorite so far is the Vivace Dolce it has the chocolate taste you are looking for, its nutty and has sweet caramel flavors too. Its fairly forgiving of technique and produced excellent thick redish crema I picked some up at  Walnut street cafe in Edmonds (awesome BTW) it was $12.50 for 12oz bags, Espresso Vivace is on Broadway in Capitol Hill and Downtown on Yale. Your equipment is great the MDX is a fantastic grinder and everyone speaks very highly of the Oscar so stick with it everything will come together.
If you have specific grinder questions Wayne who already posted will be able to answer them for you I am not sure if my dialing in essay I mean post :) was to difficult to follow or helpful at all. Good luck!

Good catch Tricia!
I hadent noticed multiple questions and I didn't connect the costco beans question.

OP.... you have no hope of  working the bugs out on stale coffee!!!!

PLEASE do yourself a favor, buy some fresh...less than two weeks from roast beans! You will drive yourself loony if you don't!

Thank you all for the replies and thanks Wayne for the encouraging words from the other posts.  I've tried stumptowns hairbender at their cafe and found that the espresso shot I bought was bitter, not a lot of crema and a bit sour couldn't really see much crema as if the shot was underextracted.  Bought some beans pulled some shots on my own had good crema but the color was not a redish color so I adjusted the grinder to be a bit finer because the color was slightly brown.  Thought I got a good shot but it drove me crazy to find what was a REALLY GREAT shot and then in the midst of trial and sipping on cups of espresso I ran out of hairbender.  2 Days ago I went to Vivace and bought a bag along with a shot to compare what I should be aiming for.  For some reason I felt like i've gotten two very horrible shots from both stumptown and vivace as I noticed that the shot was not really deep red but dark brown, had only a 1/3 of the espresso cup filled and the shot was a bit bitter.  So I asked the gentleman who poured the shot as to what I had to look for and felt possibly I could be wrong that that was actually the right shot and I was expecting something else.  I went home and set the grinder at the same position as I previously had on the hairbender and tried to replicate the shot. From there on it just drove me crazy because I tried to get crema, have the redish color while trying to aim for a 25-28 sec shot.  After pulling endless amounts of shots I stopped and looked online to find different ways to get that "Perfect Espresso Shot".  I guess in the end I didn't aim for the 25-28 sec range as the gentleman from espresso vivace told me he followed but stopped the shot when it started to blond. All in all it still kills me to see that I still don't actually know what i'm supposed to look for in an espresso shot.  I mean I love some of the shots i've pulled but just drives me crazy to know that it's the the right color or was brewed slightly faster or slightly slower than the recommended time. I feel like I have a the right grind but there are so many variables like the water temp, the amount of pressure of tamping and I keep telling myself shot after shot there is a better shot if you do this or that.  That's why I sometimes feel instead of spending so much money on bags of beans which goes by in 2 days why not just pay for an espresso shot at a cafe, but then again after having bad experiences with shots I think to myself why not do it yourself.  So i'm just going through a vicious cycle, on one hand I don't want to spend so much money on beans and the just stop and go to a cafe.  Hence the reason why I bought costco's beans because i can practice and have many trials but then again like you guys said I should use fresh beans.  I'm just in a big fat dilemma, hope you guys understand my frustration now.  Any input or suggestions will help greatly thanks for reading!

I guess to sum up what I just said is, I still haven't tasted a GREAT espresso shot yet to compare my shots to.

Great espresso tastes great (to you). It doesn't necessarily look great. Why are you so focused on reddish crema?
The only reason crema should be of concern should be in terms of mouthfeel - or espresso porn photo shoots where taste isn't an issue.

Espresso cups are often 60-90ml and so 1/3 of a cup is standard for many "3rd wave" cafes. If you want a shot of espresso that fills a demitasse with lots of reddish crema that doesn't taste bitter... I think you are wanting too much.

great to see your post. Hopefully I am not digressing here but ...  the amount of coffee-in-the-cup changes dramatically with the same setting on my MDX. Here some background. I have a T-80 Fiorenzato with a collar and notches to set the grind. Since weighing the coffee-in-the-cup I found I had to make a 'blend' of two notch settings. So I thought a stepless grinder would make it easier to achieve consistent results.
So I bought a used MDX grinder a few weeks ago. It was only used for six weeks. It was shipped postal system in the original box. It appeared to arrive in perfect condition. After some days I finally found a setting of  6.5 to 6.75 was very close. ( my goal 45 grams of coffee in the cup in 30 seconds.)
Here is the problem: With the knob at 7.0 opposite the stationary '0' I get the following weights of coffee-in-the-cup (ie successive double shots) ; 55g, 49g, 37g, 3.3g. Even when the knob is NOT moved the weight of coffee drifts dramatically.
It is hard to imagine as simple and robust as grinders are that any damage occurred during shipping.
Any thoughts?Next step is to see if a screw is loose holding the top burr.

BTW: "  ...and just wondered do you have to adjust the grinder for different beans you purchase?" Absolutely!
Recently purchased beans from a different roaster and it took 6 days (two doubles per day) to find the right setting ... on the Fiorenzato).

Are you cleaning the chute between the grind chamber and the doser after every shot?

I use mine at work so it gets cleaned out each time it is used and like when I use a SJ, I use a chop stick to reach into the chute between the grind chamber and the doser every shot. I have seen the coffee come out more or less for every shot depending on the "flow" of the grounds through the chute. With my MDX, I grind per shot, but at work I do not have a scale so I tend to grind a little more than need, dose into the PF then strike the excess from the top of the PF with my chopstick. I can get a fairly constant dose that way but of course, not as accurate as using a scale.

With my SJs, I use a dark room timer to run the grinder a set time for dosing with the bean hopper filled. I again clean the chute but as I DO have a scale at home, I check the dose at the start of the session, adjust the time and clean the chute after each shot with consistent results.

All I can do is tell you what I am doing that works for me. YMMV!

thanks Wayne, I grind about 15 gr (weigh it into the PF afterwards) then empty the doser chamber, but not the chute. Good point. I will try that. The fit of the bean hopper lid is so 'perfect' that sometimes I close the lid quickly to push out some ground coffee out of the chute.
