The shop is buzzing, literally, We’ve been running Othermills all week to find the best speeds and feeds for each material and bit combination.
Alana’s brass scorpions. The one on the left was cut using a v-cutter and the one on the right with a 1/16th flat end mill.
The fun side effect of this is that we get to make lots of great projects. The picture to the right shows a scorpion etching in brass that Alana’s mother asked her to make.
We are taking full advantage of the fact that our hardware team is a bit ahead of the software team right now. As we designed the Othermill, we noted where we could make design changes in later versions to improve speed, quality, noise, reliability, etc. We are implementing those changes now.
The most important improvement is a wholesale rethink of the spindle design. While the old design was good, it had a few drawbacks, mainly a limitation on the bit shank size. The new spindle includes an ER-11 collet holder. There are ER-11 collets available in lots of imperial and metric shank sizes, increasing the number of tools you can use with the Othermill. In addition, we’ve redesigned the belt drive to be even quieter and longer lasting.
The updated spindle design undergoing testing two weeks ago.
As promised we got our first shipping package test back and it was not acceptable. So we’re going back to the drawing board, and we’ll test an updated package design next week. It is incredibly important that our packaging provide adequate protection while the Othermill is in transit, so we’re going to keep testing until we get it right.
