An overview of the construction and use of a soundproof CNC Mill enclosure, or How I Learned To Stop Worrying and Love the Proxxon MF70
The Proxxon MF70 is a tabletop 3-axis micro mill. It’s also a pretty loud machine, which makes applications in “urban” environments difficult and the possibility of noise complaints rather high. Hence, the plan…
- a soundproof, or as proof as it gets, box
- CNC conversion of the mill (3 nema17 steppermotors and arduino grbl board)
- remote control over the network with cncjs running on a Raspberry Pi
- visual feedback with the ledstrip (machine state, door state, …)
- camera feed
- laser marker
Getting some wood, taking dimensions, PU foam hell…
Resoldering the RGB controller for the ledstrip, so it can be controlled from the Raspberry Pi (BCM 17, 27, 22 & Ground). The reed-switch at the door is connected directly to BCM 23 & Ground (the magnet is embedded in the top of the door). And a salvaged laser… could come in handy later on.
The Sound of Silence
With little to no experience in soundproofing anything, I decided to use my ears… Foam, padded walls and uneven surfaces seem to do “a” trick.
In addition: a primitive, but effective locking mechanism…
Some motor action.
