For anyone confused about the Maker's functions, "Produce" makes anti-creeper at the chosen rate (1x, 2x, 4x). "Charge" produces anti-creeper, but keeps it inside the maker. The bar fills up to show how much anti-creeper is inside. Click the burst buttons to release this creeper all at one time, or 10% at a time. "Vacuum" sucks up anti-creeper at whatever rate, and converts it back into ore so you can use it somewhere else. However, it only converts anti-creeper into ore if you have enough ore storage to hold it. If not, it won't absorb your creeper. Hope that clears some things up.
