Subject: HELP! About a used MDX grinder I bought recently
 

I am still pretty new into this home espresso, and is still in the stage of a beginner.

So I recently purchased a used Nuova Simonelli MDX Grinder off of eBay, and after cleaning it very thoroughly,

I tried to test out the grind using the coffee beans I bought

After trying to dial in and adjust the grind I barely notice any difference from the settings between "very coarse" to "fine" in the grind.

the grind stays the same and looks like sugars and salt,

I don't know if I done it wrong, or if the grinder not usable, or the grinder burrs are too dull.

I do notice the difference between fine to very fine, it turns into powder-like, and is too fine for espresso.

but from fine to coarse, it doesn't change much at all, even if I turn the grinder level to max coarse setting.

Is MDX grinder not capable of making coarse grind?

I have no hands on with the MDX but I can tell you it was built for espresso only use.  I'm sure at it's current calibration you can get espresso or maybe drip out of it but if your looking for a course grind for say French Press you may need to re-calibrate the grinder.  Are you just trying to dial in your espresso or are you trying to use the MDX as an all purpose grinder?  When your dealing with espresso range fineness in the grinds they will look almost the same to the naked eye.  The truth is in the espresso pull.  If you are able to choke your espresso machine with it's current burr set then the burrs are still good.

what i meant was when im trying to calibrate my grinder to the coarse setting it still came out espresso grind, even when i calibrate to the very coarse, it still didnt change a bit.
it seems that my burr are locked and wont adjust, probably cause i calibrate it while the grinder are turned off and calibrate it way too fine. I took the hopper off, unscrew and took away the top burr, i noticed that while i move the adjustment setting the burr didnt move a bit. could it be that the burrs are locked? right now whenever i tried to calibrate a bit to the finer setting, the burrs stucks and wont move. :(

As Chris said, it is an ESPRESSO grinder, not a general use grinder, do not expect it to grind very coarse, it is not designed to do that.  Espresso is a VERY fine grind. What kind of coffee brewing are you trying to grind for?
