Hey Butch,
try to avoid putting two very different topics into one thread. Other users who search the forum will not find that “How does loading and running programs work” matches your new topic “Using full Z axis height”. Better create one thread for each topic, or join an existing thread that has the same topic. For this, please use the forum search engine to find those, your question regarding full Z height / Raising the machine’s feet has already been discussed before. In order to find the most recent posts for a certain topic, change the result list from “Sort by Relevance” to “Sort by Latest Post” on the top right of search results. Most recent threads will then be listed on top of the list.
Moving this to a new topic:
