Read the three result types differently

Documented support means the cited source names that ingredient or form for the selected model; read the conditions in the result before proceeding. Explicitly excluded means the source rules it out. Not yet confirmed means this site has not verified the exact combination, so it is not an instruction to try a small amount. Follow the source link and check your supplied manual. If neither resolves the combination, ask the manufacturer before milling.

Keep the ingredient form in the question

Dry field corn and unpopped popcorn are separate options, as are dry non-parboiled rice and parboiled rice. Whole hulled oats and rolled oats also have separate entries. A permission for one form does not cover the other. For example, the documented Mockmill 100/200 results distinguish supported dry field corn from excluded popcorn. Changing a selector lets you inspect those differences; it does not change the permissions of the machine you own.

Match the machine and its installed parts

Select the exact model family rather than a similar brand name. WonderMill Electric and Wonder Junior are different systems. For Wonder Junior Deluxe PLUS, the required heads and auger depend on the ingredient, so this checker leaves the combination unconfirmed until the actual configuration is established. Standard Mockmill 100 and 200 records do not describe Lino or Professional versions. Regional units and manual revisions still need checking even when the family name matches.

Make the remaining checks before a batch

A supported result does not measure flour fineness, establish bowl clearance or confirm the contents of an Amazon offer. Read the exact startup, adjustment and collection instructions before adding grain. Use the first-batch guide to organize that preparation and the notebook to record a permitted batch afterward. Mechanical ingredient support is also separate from dietary suitability; the gluten-free milling guide explains why sourcing and prior machine use require their own consideration.
