CNC milling an HDPE enclosure for a 14.4V 95Wh battery pack to use as a DIY v-mount camera battery. SAFETY NOTE: if you're not comfortable with the failure modes of these types of batteries, don't build one!

Tool stickout and workholding can help you mill more quietly, but also important are the mounting of the mill on your bench and the speeds and feeds you're using. Sometimes a deeper, more aggressive cut is quieter! The software I'm using is custom built, but it's similar to software called "Millalyzer." UPDATE: it's now hosted at cutcalculator.xyz Sorry for the poor audio quality, I was using t...

When you've built your own mill, you need to square it up beyond what most mill owners need to do. Here's my set of steps to ensure all axes and surfaces are sufficiently square and parallel.

The X axis bearings constraining the lead screw failed in an odd way. I replaced one with a double angular contact bearing that I've used successfully elsewhere. Most ballscrews you buy come with a fixed side and a floating side. The floating side allows axial motion, the fixed side does not. The fixed side is implemented on those by machining the end of the ballscrew with a shoulder plus a bol...

CNC milling a DIY camera tripod quick release adapter shift plate for my Canon EOS-M.

Here are my steps for bCNC (units are inches): * zero out axes just above the pcb * probe down to zero * zero out z * jog up on z 0.1 * go to autolevel * click margins * change N resolution * change z min max to -0.1 0.1 * set probe feed to something like 1 * click scan * go to probe * enter WPOS x and y into probe pos entry * click probe * zero z * in autolevel, click zero * jog up on z 0.1 * ...

Parts list is here: pastebin.com/raw/qTwZPJzE Note that the base width in the video isn't what I used. My base is 7 inches wide, not 6, because I got a good deal on an off-cut. I wanted to show prices for building it new, so that's why I put 6 inches width for the base; the supplier I looked at didn't have an option for 7 inches wide.

More Mill Upgrades: No More Aluminum Extrusions

A comparison of an FDM PLA 3D printed electronics case versus the exact same case CNC milled out of plastic.

WARNING: loud obnoxious chatter sounds! Other stuff I tried that didn't make the video: * higher/lower RPM * higher/lower feedrate * conventional milling This is the source of the text excerpt about coatings: www.radical-departures.net/articles/understanding-the-elements/
