I recently replaced the burrs in a 10 year old Solis Maestro grinder. (Now branded as a Baratza machine).
It now makes a wonderful fine, consistent grind, but will not adjust to make a coarse enough grind for use in a press.
The replacement outer burr would not fit in my old machine, so I had to remove the old burr from its plastic housing, and put the new burr into that. As well, I also replaced the bin that feeds the beans.
Any ideas as to how to solve this problem? Just about the only coffee I drink is from my press.
"There is NO adjustment on the old Solis mechanism, that is why we created
one when we did our own gearbox. He should remove the cone burr again and
remove any washers under the white paddle wheel. This will allow the cone
burr to ride a little lower hence increasing the distance between the
burrs and giving coarser grind."
That's incredible, that you actually know and e-mailed the engineer! I thank you for taking the time, and for your help. I thank Kyle also. I would agree, that is definitely awesome after sales service, to get advice for a 10+ year old grinder.
I dug a little deeper and found some great repair manuals on the Baratza site. But Kyle is right, my machine is a tiny bit different. There is no adjustment screw, and also there is no silicone seal in my grinder.
I am going to completely disassemble it, and I'll see if Kyle's advice helps. Also, it is possible that I went wrong when I replaced the new outer burr holder with the old one. Perhaps if I have the machine apart, and am more persistent, I'll be able to fit the new one that came with the new burr, and that might make the difference there.
Too busy to do this right now, but I will keep you posted.
