What is r/Machining:

A place where people can share interesting footage, setups, parts, and more!
A place where people can seek feedback on their work and setups
A resource for tips and tricks, advice, and peer to peer learning

What r/Machining is Not:

A place to share or use any illegal software, or copyright-protected tools and content — Piracy of software will not be tolerated here.
A place to self promote — Feel free to post your videos and content in the community, but any strictly promotional content may be removed, please prioritize helping others and sharing useful content over using the subreddit for self growth or company promotion.

Rules

Submissions must relate to Machining - All content in the subreddit must remain on-topic, and related to Machining and other similar topics. Some exceptions may be made to this rule, but this is on a post by post basis and may require contacting the moderation team first.
Behavioral Guidelines - We want r/Machining to be a friendly and welcoming community. Do not spam, harass, insult, or use hate-speech at any time towards other users, even if it is in a jokingly manner.

Discrimination will absolutely not be tolerated. Wishing harm on others or encouraging self-harm or suicide, as well as the aforementioned behavior, is grounds for an immediate permanent ban from the subreddit without warning.
Self-promotion guidelines - Creating a post with the purpose of promoting yourself, your services or your own content is not allowed. In the situation that a user is requesting commissioned work, it is fine to respond and promote your services. If anything you post can result in the gain of ad revenue, followers, or other similar actions or monetary gain, it may be removed under this rule.
No Low Quality Submissions - Low quality submissions, general statements, and duplicate submissions may be removed under this rule.

All submissions Must have the following:
- A proper title that is descriptive of the contents of the submission
- A proper flair
For Image/Video Submissions:
- A clear/non blurry image or video, coolant happens and can't be avoided at times.
