Editing Othermill CNC (section)

=The Hardware=

The Othermill is a high performance portable desktop CNC mill with 0.001" precision. The marketing refers to this as "6 mill trace-and-space", meaning you can design SMD circuits with 6 mill resolution of detail for millable features, dependent of course on your milling tool's precision.

This was purchased from Other Machine Company using [[User:Tdfischer|tdfischer]]'s employee discount on top of it being a scratch-and-ding refurb for $2699 using the Noisebridge [[Equipment Fund]].

The Othermill is powered by a [https://synthetos.myshopify.com/products/tinyg TinyG controller board], which is a 100% Open Source and Open Hardware motion controller for CNC machines. The code is GPL'd and available [https://github.com/omco/tinyg on github.com/omco/tinyg]. The TinyG speaks serial at 115200 baud using a pair of USB serial ports on one device. One port is used for the TinyG JSON api, the other is used for regular GCode. Read up on the TinyG documentation to learn more.

It also has electrical circuit touchoff, meaning you can issue a G28.2 probe movement in a direction and the machine will report (via JSON ;() where it made contact with the spoilboard/t-slot bed. This operates on electrical conductivity with the Y bed, so don't get smart and think you can probe non-conductive materials with it!
